water treatment
Water treatment is the Process of removal of contaminants from untreated water to produce drinking water that is pure enough for the most critical of its intended uses, usually for human consumption. Substances that are removed during the process of drinking water treatment include suspended solids, bacteria, algae, viruses, fungi, minerals such as iron, manganese and sulfur, and other chemical pollutants such as fertilizers.Preliminary treatment of wastewater generally includes those processes that remove debris and coarse biodegradable material from the waste stream and/or stabilize the wastewater by equalization or chemical addition. Primary treatment generally refers to a sedimentation process ahead of the main system or secondary treatment.
In domestic wastewater treatment, preliminary and primary processes will remove approximately 25 percent of the organic load and virtually all of the nonorganic solids. In industrial waste treatment, preliminary or primary treatment may include flow equalization, pH adjustment or chemical addition that is ex-tremely important to the overall treatment process.
Waste water treatment can involve physical, chemical or biological processes or combinations of these processes depending on the required outflow standards.
Conventional water treatment concepts blended with Modern technology is offered by Canadian Clear in their pressure sand filter, activated carbon filter, de-mineralizes, softener, iron removal filter, fluoride removal of plants, ozonators, ultra violet sterilizers, ultra filtration, micro filters, nano filtration, electro deionization, reverse osmosis system and so on.
Canadian Clear advanced research and development wing has developed systems for various applications in prime industries like off shore oil rigs, fertilizers, hospitals, refineries, etc.
We have an offer of effective water treatment plants which are automated to remove several captions and anions from the contaminated water. Our plants are entirely free from virus attacks and bacterial elements. These systems are durable, automatic, reliable and trustworthy to offer efficient and safe operation.

Filtercon consumer presentation without sound
The document discusses hydromagnetic conditioning systems that use magnetic fields to prevent scale buildup in pipes and equipment. It explains that most scale-causing substances are diamagnetic, meaning they do not have a permanent magnetic moment and can lose their polarity over time. When this happens, the substances clump together and form scale. However, exposing diamagnetic substances to a magnetic field causes them to regain their magnetism through induced polarization. This prevents the substances from clustering together and forming scale, keeping them suspended in fluid systems instead. Hydromagnetic conditioning systems provide optimized magnetic energy to induce this polarization and prevent both new and existing scale buildup.
CONVENTIONAL METHOD – WASTE WATER TREATMENT.pptx
Water is a precious resource and without it life is not possible on earth
Water is getting polluted day by day due to excessive and careless use so the percent of available drinking water is reducing
There are many ways which causes water pollution and the effects of it are very harmful for all living and non-living objects
In general, sewage contains dissolved solids, suspended solids, nutrients (N, P), sulphate, chloride and heavy metals (Fe, Cu, Co, Zn, Pb, Ni), bacteria and viruses.
This 0.1% contains organic matter, microorganisms and inorganic compounds.
Of the solids present in sewage, 70% are organic and 30% are inorganic in nature.
The organic fraction contains proteins (60%), carbohydrates (20%) and fats (10%).
The inorganic fraction contains grit, salts and metals.
The Sewage Treatment Process essentially includes three stages. What are the three stages of sewage treatment and How does each stage work?
The three stages can be divided into primary, secondary, and Tertiary. In each step, water is purified to the next level to access clean water for humans and the environment.
1.This stage essentially includes the process of sedimentation. The water is held in the large sedimentary or rainwater tanks where the settleable solids are removed. Since the sedimentation tanks work on the principle of gravity, the solids settle at the bottom, and the lighter solids float in the tanks. Anyhow, let's move forward to stage 2 of secondary treatment. After the sludge settles at the bottom, the water is then released for its secondary treatment.
2.In this process, waste is broken down by aerobic bacteria and incorporated into the wastewater system.
3. Tertiary treatment is also known as polishing and disinfecting the water with the highest standards. This stage is critical to producing the water to a particular specification such as technical water, mineral water etc. It is also used to treat the water in public systems.
1.the incoming wastewater passes through screening equipment where objects such as rags, wood fragments, plastics, and grease are removed. The material removed is washed and pressed and disposed of in a landfill. The screened wastewater is then pumped to the next step: grit removal.
2. In this step, heavy but fine material such as sand and gravel is removed from the wastewater. This material is also disposed of in a landfill.
3. The material, which will settle, but at a slower rate than step two, is taken out using large circular tanks called clarifiers. The settled material, called primary sludge, is pumped off the bottom and the wastewater exits the tank from the top. Floating debris such as grease is skimmed off the top and sent with the settled material to digesters.
4. In this step, the wastewater receives most of its treatment. Through biological degradation, the pollutants are consumed by microorganisms and transformed into cell tissue, water, and nitrogen.
5. Large circular tanks called secondary clarifiers
Science ACE--NEWater
Wastewater is collected and purified through a multi-step process to produce NEWater. The process includes wastewater treatment using sand filters, microfiltration to remove solids and microorganisms, reverse osmosis to remove viruses and other particles, and final ultra-violet disinfection to make the water potable. Filtration methods like microfiltration and reverse osmosis use semi-permeable membranes to separate purified water from wastewater, while ultra-violet disinfection sterilizes the treated water without separation. It took 30 years to develop this purification process to reclaim wastewater as a source of drinking water.
Treatment of water for drinking purpose
This document discusses the treatment of water for drinking purposes. It outlines the microorganisms commonly found in domestic water supplies and describes the multi-step water treatment process. The primary treatment involves coagulation, flocculation and sedimentation to remove solids. Secondary treatment uses filtration to remove remaining particles. Tertiary treatment employs disinfection methods like chlorination and ozonation to kill microbes. The overall process aims to produce potable water that is safe for human consumption.
Sewage treatment
This document provides an overview of the sewage treatment process. It begins with an introduction to sewage treatment and its importance. It then describes the various stages of treatment - preliminary (screening), primary (settling), secondary (trickling filters or activated sludge), tertiary (additional filtration), and solids processing (digestion or composting). The final effluent is disinfected before discharge while solids are disposed of in landfills. The document outlines the key objectives, processes, and equipment used at each treatment stage.

BY PRODUCT AND WASTE UTILIZATION IMP TOPIC
The document discusses waste and by-product utilization. It covers two main topics: (1) the microbiology of waste and residues of chemicals like insecticides, pesticides, and fungicides, and (2) tertiary waste water treatment processes like filtration, phosphorus and nitrogen removal, and disinfection. Microorganisms play a key role in waste degradation, and bacteriological analysis is used to analyze water quality. Tertiary treatments further remove contaminants through physical processes like filtration and chemical processes like chlorination.

The document summarizes the process of treating water for drinking purposes. It discusses three levels of treatment: primary, secondary, and tertiary. Primary treatment includes coagulation, flocculation, and sedimentation to remove solids. Secondary treatment is filtration to remove additional particles and microorganisms. Tertiary treatment is disinfection through methods like chlorination or ozonation to kill remaining pathogens. The overall water treatment process aims to remove solids, organisms, and chemicals to produce potable water safe for human consumption.
2.4-water-purification.pdf
The document discusses various methods for water purification at both small and large scales. At a small scale, methods include boiling, filtration through muslin cloth, and chemical treatment with substances like bleaching powder or chlorine tablets. Large scale methods include slow sand filtration and rapid sand filtration. Purified water and distilled water are produced through additional filtration and boiling processes, respectively, and are used for various applications where high purity is required like in pharmaceutical, medical, and laboratory settings.
WASTE WATER TREATMENT
The document discusses waste water treatment. It defines sewage and its classes. Sewage contains domestic and industrial waste waters. Treatment is necessary to prevent hazards and pollution. Methods include single dwelling unit treatment with septic tanks and municipal treatment processes. The municipal process involves primary treatment to remove solids, secondary treatment using biological methods like activated sludge to reduce organic compounds, and sludge processing. Activated sludge treatment uses aeration of sewage to form flocs to oxidize organic matter. The sludge is further treated through anaerobic digestion or composting.
Water recovery from sewage by absolute water
1) The document describes a process called vermi-filtration that uses earthworms and microorganisms to treat sewage and recover water for human consumption.
2) The process involves two steps - a biofilter system that uses vermiculture and microorganisms to treat raw sewage, followed by a membrane filtration system to obtain drinking water from the treated water.
3) Testing shows the treated water meets WHO and BIS drinking water standards, while the reject water from the membrane can be used as liquid fertilizer due to its nutrient content and low BOD levels. The process provides a decentralized and sustainable solution to water scarcity and wastewater treatment.

water treatment.pptx
This document summarizes Janani K R's presentation on water treatment. It discusses the three main types of water treatment: drinking water treatment, wastewater treatment, and industrial water treatment. Water treatment involves physical, chemical, and biological processes to remove contaminants from water and make it safe for human consumption or industrial use. The goal is to produce clean water and an environmentally safe waste stream. Common treatment techniques include sedimentation, filtration, disinfection, and the use of microorganisms to break down organic materials.
DISINFECTION OF WATER.pptx
Disinfection is the process of killing or inactivating microorganisms in water to make it safe for human consumption. Common disinfection methods include chlorination, ozonation, and UV irradiation. Chlorination, the most widely used method, involves adding chlorine to water to kill bacteria, viruses and other pathogens. It is effective and easy to implement but must leave behind a chlorine residual to prevent recontamination in distribution systems. The amount of chlorine added depends on the treatment method, such as plain, pre- or post-chlorination, with higher doses used when water is heavily contaminated. Proper disinfection is necessary to prevent waterborne diseases.
Filtration Process
Filtration is a process that separates solids from fluids by passing the fluid through a medium that allows only the fluid to pass. The fluid that passes through is called the filtrate. Filtration is used to separate particles and fluids in applications like water treatment, sewage treatment, and chemical engineering. There are different types of filtration like hot filtration, cold filtration, vacuum filtration, surface filtration, and depth filtration that use various methods and filter media depending on the application. Biofiltration is a pollution control technique that uses living materials in a bioreactor to capture and degrade pollutants, and is commonly used for wastewater treatment.

L'indice de performance des ports à conteneurs de l'année 2023
Une évaluation comparable de la performance basée sur le temps d'escale des navires
L'objectif de l'ICPP est d'identifier les domaines d'amélioration qui peuvent en fin de compte bénéficier à toutes les parties concernées, des compagnies maritimes aux gouvernements nationaux en passant par les consommateurs. Il est conçu pour servir de point de référence aux principaux acteurs de l'économie mondiale, notamment les autorités et les opérateurs portuaires, les gouvernements nationaux, les organisations supranationales, les agences de développement, les divers intérêts maritimes et d'autres acteurs publics et privés du commerce, de la logistique et des services de la chaîne d'approvisionnement.
Le développement de l'ICPP repose sur le temps total passé par les porte-conteneurs dans les ports, de la manière expliquée dans les sections suivantes du rapport, et comme dans les itérations précédentes de l'ICPP. Cette quatrième itération utilise des données pour l'année civile complète 2023. Elle poursuit le changement introduit l'année dernière en n'incluant que les ports qui ont eu un minimum de 24 escales valides au cours de la période de 12 mois de l'étude. Le nombre de ports inclus dans l'ICPP 2023 est de 405.
Comme dans les éditions précédentes de l'ICPP, la production du classement fait appel à deux approches méthodologiques différentes : une approche administrative, ou technique, une méthodologie pragmatique reflétant les connaissances et le jugement des experts ; et une approche statistique, utilisant l'analyse factorielle (AF), ou plus précisément la factorisation matricielle. L'utilisation de ces deux approches vise à garantir que le classement des performances des ports à conteneurs reflète le plus fidèlement possible les performances réelles des ports, tout en étant statistiquement robuste.
