FINAL PROJECT REPORT
This document discusses using algae for wastewater treatment. It begins by noting that most of India's cities lack proper sewage treatment, polluting water sources. Algae-based treatment offers advantages over conventional methods like lower costs, energy requirements, and sludge production. It can also produce useful algal biomass. The objective is to evaluate two algae species, Chlorella and Scenedesmus, for removing nutrients from municipal wastewater. If effective, algae cultivation could replace or enhance conventional treatment while providing biomass for products like biodiesel.
Water Pollution and its control through biotechnology
Water pollution occurs from both point and non-point sources and can be physical, chemical, or biological in nature. It affects plants and organisms in bodies of water. Biotechnological control of water pollution uses aerobic and anaerobic treatment processes. Aerobic processes use microorganisms like Pseudomonas and algae to break down pollutants, and occur in suspended growth systems like activated sludge or attached growth systems like trickling filters. Anaerobic processes use microbes like Peptococcus anaerobus and Escherichia coli to treat waste in the absence of oxygen in digesters.
Water
Water is essential for life and makes up most of the Earth's surface and human body. It is used for drinking, industry, and agriculture but can become polluted. The biological oxygen demand (BOD) test measures pollution by determining the amount of dissolved oxygen consumed by bacteria breaking down organic wastes over 5 days. Higher BOD levels indicate more pollution and risk to aquatic life since less oxygen is available. BOD is used to monitor water quality and identify sources of pollution.
Phycoremediation – a clean technology for water pollution abatement
A brief review focuses on significant role and potential of algae in pollutants removal from the waste water.
Drinking water
The document describes the multi-step process used to treat drinking water. It involves pre-filtration to remove particles, addition of chemicals like chlorine for disinfection, natural and slow sand filtration to remove bacteria, and final storage and preservation of the treated water. The goal is to remove pathogens, chemicals, and other contaminants to produce safe, clean drinking water for human consumption.
Oxygen demand
The document discusses adverse effects of oxygen demanding waste. It defines biochemical oxygen demand (BOD) as the amount of oxygen required by aerobic microorganisms to decompose organic matter in waste. High BOD levels can deplete oxygen in water bodies, harming aquatic life. The document outlines several factors that can contribute to high BOD, such as temperature increases promoting faster microbial growth, and eutrophication from excess nutrients causing algal blooms. Improper waste disposal such as littering and inadequate treatment of sewage and industrial runoff introduces oxygen-depleting organic matter into the environment.
oxygen consuming wastes
This document discusses various parameters used to measure oxygen-consuming waste in water, including biochemical oxygen demand (BOD), chemical oxygen demand (COD), dissolved oxygen (DO), total organic carbon (TOC), and total suspended solids (TSS). It provides definitions and explanations of each parameter, their significance for assessing water quality, and common methods for analysis. Sources of oxygen demand are identified as natural processes like respiration and decomposition, as well as agricultural and urban runoff. High levels of oxygen-consuming waste can lower dissolved oxygen and negatively impact aquatic life.
Water impurities, bilological, chemical, physical
Water is never completely pure due to dissolved minerals and gases from the air, soil, and rocks. Common impurities include calcium, magnesium, iron, and contaminants from human and industrial activities. Impurities can dissolve in water and make it unsafe. The quality and type of impurities varies based on the water source, such as surface water, groundwater, or water from storage reservoirs. Impurities are usually measured in parts per million and can include physical contaminants like sediment, chemical contaminants, and biological contaminants like bacteria, viruses, and parasites.

Concentration Distribution and Ecological Risk Assessment of Polycyclic Aroma...Scientific Review SR
The ecological risk assessment of 16 USEPA priority polycyclic aromatic hydrocarbon (PAHs) in water and sediments of Kolo creek, Niger Delta Nigeria was assessed the samples were collected from November, 2018 to June, 2019 from seven locations (A-G) along the creek. The samples were extracted using standard methods and analyzed using gas chromatography (model: HP5890 S). The concentrations of the PAHs in the water and sediment samples ranged between 0.000 - 9.239 µ/L and .002 – 374.35µg/Kg respectively. All the compounds analyzed were detected in all the sampling places, even area far from the flow stations. Hence, the urban runoffs, sewage discharges, and agricultural activities are implicated. Four rings hydrocarbon were present in higher concentration when compared to other PAHs in all sampling sites, with benz (a)anthracene having the highest values in both matrixes. Similarly, lower molecular weight (LMW) PAHs were present in lower concentrations in all sampling sites and they are known to exhibit higher lethal toxicity than the larger PAHs. HMW were present in high concentrations than LMW and are persistent in the environment as a result of their increase resistance to oxidation, reduction and vaporization as molecular weight increases. Similarly, The PAFs of the investigated creek is less than 5%, suggesting existences of minor ecological risks that are insignificance. However, the TEQs detected in high molecular weight showed that there is possibility of cancer to those who may be exposed to the bottom sediment. The indices measured in this habitat may put more pressures to the aquatic organisms and cause drastic changes to their ecosystem which may lead to species extinction.Water Treatment and Purification using Moringa Oleifera Seed Extract
Water is the most abundant chemical and important natural resource. Various concentrations of water at given place contributes to water quality. The suitability of water and its specific use are evaluated by examining its quality parameters. The adverse health effects have been observed in developing countries due to drinking contaminated water. The natural resources have serious threat due to development and urbanization in countries. People are made to use low quality water because of high cost of treated water which results in exposing them to waterborne diseases. The seed extract of Moringa oleifera is used for purification of drinking and wastewater due to presence of soluble cationic coagulant. It has capability to reduce the turbidity from water. In the present study, the collected water samples were examined with various physical, chemical and biological parameters. Obtained values of each parameters were compared with standard values set by World Health Organization.

Conversion of Seawater and Carbon Dioxide into Biofuel/Food and Sweet Water, ...
Ecochip is ‘ecology on a chip’. 100 mg of BIOSANITIZER Ecochip has the same
capability as 1 acre of natural forest, of using inorganic nutrients(salts) and CO2 as
food and produce eco-resources (food/fuel and oxygen).
Summary: BIOSANITIZER Ecochips (bio-catalyst) help us utilise three pollutants (salts, carbon dioxide and warmth) as free raw materials. BIOSANITIZER makes the salts usable, as nutrients for the plants. Salty water, thus, can be utilised to grow crops that produce food, fuel, etc. Shallow wells, then are used to collect the sweet water. Carbon dioxide from the air also gets sequestered during the process. Economic recession, thus, can be resolved through the creation of eco-jobs using this innovation.
Lemna Minor Yousaf Riaz
This document summarizes a study on using Lemna minor (duckweed) to treat wastewater in bio-treatment ponds in Pakistan. The study evaluated the effectiveness of duckweed in removing heavy metals from wastewater ponds constructed at the National Agricultural Research Center. Analysis found that duckweed accumulated higher concentrations of heavy metals like zinc, lead, nickel, manganese, and iron compared to the wastewater. The treated wastewater met parameters for reuse in aquaculture and agriculture, and the plants around the ponds were healthy. The study demonstrated that bio-treatment ponds could be an effective wastewater treatment approach in Pakistan.
pollutant levels of the lake water of Tadie
This document summarizes a study that assessed pollutant levels in Lake Tadie in Mampong Ashanti, Ghana. Water samples were collected from 5 points around the lake and analyzed for physicochemical and biological parameters in a laboratory. The results found that temperature, total dissolved solids, and levels of sulfate, nitrate and phosphate were within recommended limits. However, pH levels and concentrations of iron, lead and fecal coliform bacteria exceeded guidelines. The acidic pH is likely due to runoff of fertilizers and waste from surrounding agricultural and residential areas entering the lake. Overall, the lake water quality has been impacted by human activities in the area.

Three distinct agricultural waste materials, viz., casuarina fruit powder (CFP), sorghum stem powder
(SSP), and banana stem powder (BSP) were used as low-cost adsorbents for the removal of toxic lead(II)
from aqueous solutions. Acid treated adsorbents were characterized by scanning electron microscopy (SEM),
energy-dispersive X-ray spectroscopy (EDX), and Fourier transform infrared spectroscopy (FTIR). The
effects of parameters like adsorbent dose, pH, temperature, initial metal ion concentration, and time of
adsorption on the removal of Pb(II) were analyzed for each adsorbent individually and the efficiency order
was BSP > SSP > CFP. Based on the extent of compatibility to Freundlich/Langmuir/Dubinin–Radushkevich/
Temkin adsorption isotherms and different models (pseudo-first and second order, Boyd, Weber’s, and
Elovich), chemisorption primarily involved in the case of BSP and SSP, whereas simultaneous occurrence of
chemisorption and physisorption was proposed in the case of CFP correlating with the thermodynamic study
results conducted at different temperatures. Based on the observations, it was proposed that three kinetic
stages involve in the adsorption process, viz., diffusion of sorbate to sorbent, intra particle diffusion, and then
establishment of equilibrium. These adsorbents have a promising role towards the removal of Pb(II) from
industrial wastewater to contribute environmental protectionThermodynamic Study of Adsorption of Phenol, 4-Chlorophenol, and 4-Nitropheno...

Study of removal effect on mesocycops leukarti
This document summarizes a study on using various oxidants to remove Mesocyclops leukarti, a type of zooplankton, from drinking water sources in China. Through bench-scale experiments, the authors found that chlorine dioxide was the most effective oxidant at inactivating and removing M. leukarti. A full-scale test at a water treatment plant then showed that pre-treating water with 1.0 mg/L of chlorine dioxide, along with conventional filtration processes, could fully remove M. leukarti from the water. Additional tests revealed that water treated with chlorine dioxide preoxidation contained fewer organic substances and lower mutagenicity than water treated with prechlorination.

IRJET- Organic Wastewater Treatment using Enzyme Immobilization
This document summarizes a study on using enzyme immobilization to treat organic wastewater. Wastewater was collected from a restaurant in Kollam, India containing high levels of biodegradable organic matter and oils/greases. Lipase, protease and amylase enzymes were extracted and immobilized onto clay beads to degrade proteins, starches and lipids in the water. The wastewater was passed through a filtration column then separating funnels containing different enzyme-immobilized clay bead combinations. Analysis showed rough clay beads with mixed enzymes provided the best treatment, reducing pollutants by 65%. Key water quality parameters like BOD, COD and oil/grease were significantly decreased, showing enzyme immobilization
