Water is a transparent and nearly colorless chemical compound that is the main constituent of Earth's streams, lakes, and oceans, and the fluids of most living organisms. It has a density of 1 g/cm3 and boils at 100°C and melts at 0°C. Water has the chemical formula H2O.
Water
Glaciers are melting rapidly due to climate change, which will have significant environmental consequences. Rising temperatures have caused glaciers and snow cover to decline sharply in some regions over the past decades. This glacier melt poses problems for rivers and winter tourism industries that rely on natural snow. Solutions proposed include using more environmentally-friendly practices for artificial snowmaking and limiting various forms of pollution from ski resort activities and tourism to protect threatened species.
Pollution
Water evaporates from bodies of water and rises into the atmosphere with heat. As the warm air cools and expands higher in the sky, the water vapor condenses into droplets which grow larger. When the droplets become too heavy, they fall to the ground as rain, snow, sleet or hail. Air pollution occurs when fossil fuels are burned, releasing nitrogen and sulfur oxides into the atmosphere. These gases can dissolve into acid rain and particles can reduce visibility and impact health. Water covers most of the earth but is found in oceans, ice caps, snow, and underground. Many areas face water shortages in summer and rural populations must travel long distances to collect water. Water availability determines what species can survive in an area
Water
This document discusses the water cycle and where water can be found. It explains that there are three states of matter: solid, liquid, and gas. It then outlines the water cycle, describing the processes of evaporation, condensation, and precipitation, and how water is recycled through these processes as it moves from the sea to clouds to rain or snow back to the ground. It emphasizes that the water on Earth is limited and stresses the importance of conserving water.
Global Warming
This document provides an overview of a session on global warming, including its definition as the observed increase in average temperatures of the Earth's atmosphere and oceans, primary causes as carbon dioxide emissions from human activities, and effects such as rising sea levels and increased extreme weather events. Prevention methods are also discussed like using renewable energy and public transportation to reduce carbon dioxide emissions.
Ice
Since 2002, Antarctica has been losing over 100 cubic km of ice per year due to global warming. Icebergs form when glaciers break apart, with pieces that range greatly in size floating away. While only the tip is visible above water, most of an iceberg's mass is submerged, posing a hazard if they roll over and cause waves.
Ppt s2u4 water and land
Most of the Earth is covered in water, including oceans, seas, rivers, lakes, underground in caves and rocks. Water exists in three forms: liquid, solid (ice) and gas (water vapor). The water cycle describes how water evaporates from the oceans into clouds, falls as rain or snow over land, and flows into rivers and lakes before returning to the oceans to repeat the cycle. Rivers have three courses - upper, middle and lower - before reaching the sea. Water is essential for life and is used for drinking, washing, cooking and by plants but must be conserved and not wasted.
Save the environment
The document discusses several major problems facing Earth's environment including increasing global temperatures caused by greenhouse gas emissions, melting polar ice caps and rising sea levels. Air pollution depletes the ozone layer and emits gases like carbon monoxide that damage the ozone. Acid rain from air pollutants harms plants and buildings. Deforestation reduces rainfall leading to droughts while pollution negatively impacts human health. The document calls for tree planting and conservation to protect the environment.

Climate Change
Global warming is causing rising temperatures that are melting glaciers and sea ice, raising sea levels and threatening islands. The climate change is disrupting wind and water patterns, bringing more extreme weather like typhoons and drought that damage land and crops. Greenhouse gases like CO2 in the atmosphere are trapping heat and need to be reduced through global cooperation to slow the temperature increase and protect our planet.
Global Warming Revision
Global warming is causing both positive and negative impacts for the UK. Potential positive impacts include longer growing seasons and the ability to grow new crops in southern parts of the country. However, negative impacts outweigh the positives, such as many coastal areas being flooded by rising sea levels, loss of farmland and natural areas, and increased extreme weather events. International agreements like the Kyoto Protocol have aimed to reduce greenhouse gas emissions to mitigate global warming, but signing and enforcement among countries has been a challenge.
Effects of melting glaciers
Glacial melting contributes significantly to various global issues. As glaciers shrink due to climate change, they no longer help regulate the planet's temperature and provide fresh water. This leads to fresh water shortages, reduced agricultural production, electricity shortages from lack of hydroelectric power, excessive flooding, sea level rise that displaces coastal communities and destroys habitats, and the release of toxic pollutants that were stored in glacial ice. If glacial melting continues unabated, its effects will further exacerbate climate change in a dangerous feedback loop.
Ocean acidification will-the_reef_survive-non-narrated[1]
The burning of fossil fuels releases 11 billion tons of carbon dioxide into the atmosphere each year, which dissolves into the ocean and causes ocean acidification. Ocean acidification threatens shell-forming organisms as a small pH change equals a large acidity change, reducing the concentration of carbonate ions needed by corals and plankton for shell formation. Experiments show yeast producing carbon dioxide that dissolves in water, lowering the pH and demonstrating how ocean acidification occurs.
Global Warming
Global warming is caused by greenhouse gases such as carbon dioxide, CFCs, methane and HCFCs released from activities like deforestation, agriculture, and industrialization. This leads to extreme weather, rising sea levels as ice caps melt, ecosystem damage like coral bleaching and extinction, and problems like desertification and infectious diseases. Individual actions like using less energy, traveling efficiently, afforestation, and conserving resources can help address the climate crisis.
20091121 Globalwarming Sw Group03
The document discusses the issue of global warming and water management. It mentions Al Goure, a politician who wants to change water consumption worldwide. Researchers agree with his views about the problems that will occur if no action is taken. The 54th state and government will attend a climate meeting in Copenhagen to reduce carbon emissions by 20-30% globally. Global warming is leading to melting glaciers and rising sea levels, threatening water access and food production for many people. Expensive infrastructure projects will be needed to address the effects, and some island nations may disappear entirely, presenting economic and security challenges.

The document discusses evidence of global warming in Antarctica. It notes that the Antarctic Peninsula has warmed 2.5 degrees Celsius over the past 50 years, much faster than the global average. This rapid warming led to the Larsen B ice shelf, the size of Cornwall, breaking off in 2002. While temperatures have increased on the peninsula and parts of the West Antarctic ice sheet are thinning, the East Antarctic ice sheet does not show signs of warming. Global warming is also affecting the Southern Ocean by causing earlier sea ice melt and more ice-free areas in summer. This is impacting the Antarctic marine ecosystem as warmer waters reduce phytoplankton and krill populations.
Catalonia
Catalonia has been partially submerged due to rising sea levels caused by climate change. The climate has also warmed, lengthening summers and making winters hotter. As temperatures increased, Scotland is now able to produce wine and champagne by cultivating vineyards, whereas the climate was previously too cold. Snow and animal habitats are disappearing as temperatures rise and deserts expand.
Global Water Cycle in Hawaii
The document discusses the global water cycle, explaining that water is essential for life and circulates around the Earth in a continuous process. It describes the major components of the water cycle, including evaporation, transpiration, condensation, precipitation, infiltration, and collection. The water cycle is driven by energy from the sun, which causes water to evaporate from oceans, lakes, and other bodies of water before condensing in clouds and falling as precipitation only to be collected and start the cycle again.

Global temperatures have risen since 1880 due to increased greenhouse gases, with the top 10 warmest years occurring in the last 12 years. The oceans have warmed by 0.3 degrees Fahrenheit in the top 700 meters since 1969. Both the Greenland and Antarctic ice sheets have been losing over 150 cubic km of ice per year since 2002, and glaciers around the world are retreating.

Global warming is causing ice caps and glaciers to melt due to rising temperatures on Earth and in the oceans, which is raising sea levels and putting coastal communities at risk of flooding. Some ways to help stop global warming include planting trees to produce oxygen, walking instead of driving to reduce greenhouse gas emissions, and taking showers to conserve water.
THE POLAR ICECAP AND GLOBAL WARMING.pptx
Polar ice caps are large dome-shaped sheets of ice found near the North and South Poles that form due to the low temperatures in these high-latitude regions. Global warming is causing the polar ice caps to melt as increasing greenhouse gas emissions, especially carbon dioxide, trap more heat in the atmosphere. This is happening at an alarming rate, with the Arctic sea ice declining by almost 13% each decade and the oldest and thickest Arctic ice declining 95% over the past 30 years. The melting ice caps will have widespread impacts such as rising sea levels, more severe weather events, disruption of global food systems, and threats to wildlife and indigenous communities.

Acid rain powerpoint presentation[1]
Granite, red sandstone, and pea stone will be tested to see which holds up best against acid rain conditions. Samples of each material will be submerged in vinegar to simulate acid rain and their masses measured before and after 24 hours. It is hypothesized granite will deteriorate least since it is most resistant to weathering. The experiment will help recommend the best material for a new statue given the area's acid rain levels.
Acid Rain for 3rd & 4th Graders
The document discusses acid rain and its causes and effects. It explains that burning coal releases pollution into the air which mixes with water in clouds. When the polluted clouds rain, the rain is acidic. Acid rain harms the environment and has damaged structures like the Statue of Liberty over time by eroding the copper. The pH scale is shown to illustrate normal rain is around 5.6 while acid rain is around 4.3, and national pH levels have improved slightly from 1990 to 2010.
A survey about consuming water in 150 households
This survey asks Slovenian residents about their household water usage, including the number of taps, major appliances using water like showers and dishwashers, the approximate monthly usage in cubic meters, and whether tap water or bottled water is consumed. The survey is part of a Comenius project from 2013 to 2015 conducted by Matija Gregorič and Nik Tomić from Izola, Slovenia to better understand local water usage and promote environmental stewardship.
WATER SURVEY
The students at IES Comarcal high school conducted a survey of water usage to determine if their school is waterwise. They measured water used in taps, toilets, and green areas. For green areas, they found the school has more exotic plant species than native ones and uses a drip irrigation system, but it is not used properly. They also found leaks in the irrigation system. For taps and toilets, water flow was adequate but no posters encourage water conservation. The students calculated average annual water usage per person and concluded the school generally uses appropriate water measures but could improve by repairing leaks, using the irrigation system, and adding conservation posters.
Water means life
Water is essential for life, but pollution threatens our water supplies. To protect water, individuals need to conserve water at home by turning off taps and taking shorter showers. Littering should also be avoided, as trash can blow into waterways and prevent natural water cleaning by microorganisms. While wastewater treatment plants help clean dirty water, more facilities are still needed in some areas to prevent untreated water from flowing directly into the sea. Overall, greater efforts are required by all to safeguard water for future generations.
meet
This document summarizes the minutes from the first student meeting of the Comenius environmental protection project held in Izola, Slovenia from March 24-28, 2014. It describes the participating teachers and students from Spain, Italy, Slovakia and Slovenia. The schedule of activities included school tours, presentations on natural areas of each country, choosing a logo, and excursions to Strunjan Nature Reserve, Piran, Sečovlje Salina Nature Park, and Škocjan Caves. Cultural performances and meals representing each country's cuisine were part of a cultural night event. The concluding teacher discussion focused on the success of hosting students and whether the number of participating students should be adjusted for future meetings.
noise pollution
The document discusses noise pollution, its sources and effects. It notes that while sound is important, noise can cause unpleasant effects and health issues for humans and animals. The document describes a study by students who measured noise levels at various locations in their school, finding some classrooms exceeded recommended exposure limits. It concludes with some potential solutions like soundproofing rooms near noisy areas and restricting loud vehicles and machinery near living areas.
The sleet
The document describes freezing rain, or ice storm, which occurs when rain falls from warm air into sub-freezing temperatures, coating all surfaces in ice. This can cause heavy damage by snapping trees, wires, and poles under the weight of the ice. After an ice storm, the author and others gathered fallen wood to craft birdhouses and beehive panels.

Intermittent lake
The document summarizes an intermittent lake located in Pivka, Slovenia near city hall. The lake fills with water for 6 months each year from April to October, reaching depths of 5-7 meters long and 0.5 km wide. Though no fish live in the lake, 13 species of non-vertebrates survive the dry period as eggs and reappear when water returns. During the dry period, the lake bottom is covered in grass and is used for growing wheat due to unsuitability for farming. The document also briefly describes a farm visit where they observed horses, beehives, and tadpoles in a small pond.

Formulas were developed to calculate CO2 emissions from factors like kWh of electricity used, liters of water consumed, kg of paper waste, and km traveled by various vehicles. The results will help the school identify behaviors to modify and lower its carbon footprint.
Water 3 f
Water is essential for life, making up 71% of the Earth's surface and 60% of the human body. However, only 1% of the world's water is freshwater available for human use. Many regions face water crises due to uneven distribution and climate change impacts like increased temperatures and decreased rainfall. Countries in Southern Asia, the Middle East and Northern Africa are particularly vulnerable, with daily water consumption as low as 20 liters per family compared to 165 liters in Europe. While Italy is not lacking in water supplies, issues like temperature increases, precipitation decreases, pollution and infrastructure losses result in periods where 15% of the population has less than 50 liters available per day.

Water covers 70% of the Earth's surface and there is about 1.5 billion cubic kilometers of water on Earth. 97% is salty seawater, 2.1% is locked in ice caps, and less than 1% is freshwater. The water cycle involves evaporation, condensation, and precipitation that allows water to circulate through the biosphere. Water is essential for life and takes the form of liquid, solid (ice), and gas (vapor) on Earth.
Science primary 4 states of water
The Egyptians were the earliest recorded people to treat water over 1,500 years ago by boiling, heating in the sun, or using heated iron to clean water. They also filtered boiling water through sand and gravel.
Water exists on Earth in solid, liquid, and gas forms and is essential for all living things. It moves continuously through the water cycle by evaporating from bodies of water and the ground, condensing in the sky as clouds, and falling back to the ground as precipitation.
Today, cities treat drinking water through processes like chlorination to kill germs and make water safe for human consumption.
Water
Water is essential for life and can be found in rivers, lakes, oceans, and as water vapor in the air. It exists in three forms: solid ice, liquid water, and gas water vapor. Water has unique properties like being a universal solvent, having a high heat capacity to store heat, and existing as a liquid between 1-100 degrees Celsius. Its molecular structure of two hydrogen atoms and one oxygen atom gives water polar properties that allow it to dissolve other polar substances but not nonpolar ones.
03 unit 4 water
This document discusses where water is found on Earth, including oceans, seas, lakes, rivers, groundwater, icebergs, and mountain peaks. It explains that most water on Earth's surface is salt water, while only 3% is fresh water. The water cycle is described as the movement and changes of water between oceans, atmosphere and land through evaporation, condensation and precipitation. The document also addresses how humans use water for drinking, hygiene, cooking, cleaning, agriculture and recreation, and provides tips for conserving water such as turning off taps, fixing leaks, and only running full loads of laundry or dishes.
Geography presentation
The document discusses water resources and the hydrological cycle. It begins by defining the hydrological cycle and discussing its major processes. It then explains that water exists in three forms - solid, liquid, and gas - due to climatic variations. Water is essential for life but must be preserved and used carefully. The document further analyzes the hydrological cycle and how water circulates between the oceans, atmosphere, and land in vapor, liquid, and solid forms. It also notes that while water is abundant globally, freshwater availability does not always meet demand.
Water
Water is made up of hydrogen and oxygen molecules and covers over 70% of the Earth's surface. It exists in three states - solid, liquid, and gas - and is essential for all living things. The water cycle describes how water is constantly recycled as it evaporates from bodies of water into the air, condenses into clouds, and falls back to the Earth as precipitation. It is important to conserve our limited water resources through practices like reducing consumption and matching water levels to load sizes. Singapore has campaigned to lower daily water usage and aims to reduce consumption to 140 liters per person by 2030.

Water has the chemical formula H2O, making it an inorganic substance. It is the primary chemical component of the Earth’s hydrosphere and the fluids of all known living things (in which it serves as a solvent. It is translucent, flavourless, odourless, and almost colourless. In spite of not supplying food, energy, or organic micronutrients, it is essential for all known forms of life. Its molecules are made up of two hydrogen atoms joined by covalent bonds and have the chemical formula H2O. The angle at which the hydrogen atoms are joined to the oxygen atom is 104.45°. The liquid condition of H2O at normal pressure and temperature is known as “water” as well.
Edu653watercycle
The water cycle describes the continuous movement of water on, above, and below the surface of the Earth. Water evaporates from bodies of water and condenses into clouds, where it falls as precipitation and either runs off into other bodies of water or is absorbed by soil, starting the cycle again. Key processes in the water cycle include evaporation, condensation, precipitation, and runoff. The water cycle is essential to sustaining life and natural systems on Earth.
Water for Grade 6 by Aryana Roy
This document discusses the importance and properties of water. It begins with a riddle and then discusses key points:
- Water is essential for all living things and exists in solid, liquid, and gas forms through the water cycle.
- Humans and other organisms rely on water for biological processes like temperature regulation and digestion, as well as recreational activities.
- Plants need water for growth and photosynthesis, and many animals live in water.
- Water is used for domestic, industrial, and agricultural purposes like generating electricity, transportation, irrigation, and more.
- Water anomalously expands when freezing into ice, allowing aquatic life to survive under ice in cold regions.
Water lecture
Water is essential for life and covers most of the Earth's surface. It exists in three states - liquid, solid (ice), and gas (water vapor). Water is a polar molecule made of one oxygen atom bonded to two hydrogen atoms. Its unique properties, like being a universal solvent and having a high heat capacity, help regulate the Earth's climate and temperature. Water is distributed throughout the universe and is critical for habitability in Earth's "Goldilocks zone" where its three states can exist simultaneously.
What are the physical characteristics of water
Water is the most abundant liquid on Earth, covering about 70% of the planet's surface. It has unique physical properties like a high heat capacity and heat of vaporization. Water exists in three states - liquid, solid (ice), and gas (water vapor) - and its density peaks at 3.98°C in its liquid form. In addition to moderating Earth's climate, water is widely used as a coolant in power plants and heat exchange systems due to its heat transfer abilities.
Unit e fresh & saltwater systems
This document provides information about the distribution of fresh and salt water on Earth. It discusses how 97% of the Earth's surface water is saltwater, while 3% is freshwater. Most of this freshwater (77%) is locked up in glaciers. It also notes that only 0.003% of total water on Earth is potable/drinkable by humans. The document includes visual representations of these distributions and discusses Canada's large freshwater resources.
L'eau qui nous entoure
The document discusses water on Earth. It states that:
- Most of Earth's water is found in oceans and seas, which cover over 70% of the planet's surface. The water in oceans and seas is salty.
- Fresh water is found in glaciers, rivers, lakes, and underground aquifers.
- Water is essential for human life and is used for cooking, drinking, industry, agriculture, and more. It moves between oceans, atmosphere, and land through the water cycle of evaporation, condensation, precipitation, and flow towards oceans.
The hydrospher eb
The document discusses the hydrosphere and properties of water. It notes that the hydrosphere includes all water on Earth, which covers 71% of the planet's surface. It also notes that living things contain water in varying proportions, such as 70% for humans and 99.5% for jellyfish. The document then asks questions about where water can be found on Earth, differences between sea and river water, the water cycle, the importance of conserving water, and ways to save water.
The hydrosphere
Water is found in oceans, ice/snow, underground, in the atmosphere, and within living things. Sea water is salty due to dissolved gases, while fresh water is found in streams, glaciers, rivers, lakes, and underground. The water cycle describes the continuous movement of water on, above, and below the Earth's surface through processes like evaporation, condensation, precipitation, and runoff.
Hydrosphere
The document discusses the importance of water and where it can be found on Earth. Water is essential for life but cannot be consumed from the sea due to its salty composition. The hydrosphere encompasses all water on the planet, including underground aquifers, seas, rivers, lakes, and snow and ice atop mountains. The text also references states of water, the water cycle through song, oceans, and related questions and activities.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

About water
- 1. WATER Let’s know, let’s love, let’s protect our environment Comenius project 2013-2015 By Nejc Grbec and Gašper Jugovac from Izola, Slovenia
- 2. INTRODUCTION In this presentation we are going to talk about water. The authors of this presentations are the two of us: Gašper J. and Nejc G. We hope you will enjoy the presentation
- 3. GENERALLY ABOUT WATER We can find water in 3 different states Water molecule: Liquid state Oxygen Hydrogen Hydrogen Ice Steam
- 4. WATER ON EARTH Water is vital for all known forms of life. It covers 71% of Earth's surface. On Earth, 96.5% of the planet's water is found in seas and oceans, 1.7% in groundwater, 1.7% in glaciers and the ice caps of Antarctica and Greenland and 0.001% in clouds, fog and water vapor (steam). Only 2.5% of Earth's water is freshwater. Water on Earth moves continually through the water cycle of evaporation and transpiration (evotranspiration).
- 5. SEA WATER Sea water contains about 3.5% salt on average, plus smaller amounts of other substances. The salinity of water in major seas varies from about 0.7% in the Baltic Sea to 4.0% in the Dead Sea. It freezes at a lower temperature than fresh water (about −1.9 °C). We can find salt water in seas and oceans.
- 6. FRESH WATER We can find it in lakes, rivers … It freezes at a higher temperature than salt water (0°C) We use it for washing things, cooking , drinking, for agriculture, transport …
- 7. STEAM Steam is a term for the gaseous phase of water, which is formed when water boils (100°C). We use steam for sterilization in agriculture, for cleaning , producing electricity in steam turbines … Old locomotives and machines produced steam, too.
- 8. ICE Ice is water frozen into a solid state. We use ice for sports like: Ice hockey Curling Bobsled Skeleton We can use ice for cooling down drinks, for creating sculptures, for conserving food …
