When it comes to water purification, there are a number of water purification chemicals that are used in wastewater filtration as well as for water purification. Some of these chemicals include:
Defoamers and antifoamers which are used to control excess foam production in various manufacturing and processing plants. These are also used in wastewater filtration to control foaming of effluent and wastewater. Other applications include cooling systems, fermenting and distillation processes, steam generation, sugar manufacturing, food processing, plastic and adhesives manufacturing, paper production and various others. These chemicals can generally be purchased in a non food grade and food grade versions.
Disinfectants and biocides are especially important in wastewater filtration systems. These water purification chemicals are used to eliminate or control the microbiological activity in the water. To achieve the exact balance necessary, specific biocides are used. Various industries make use of disinfectants and biocides sin various ways such as wastewater filtration, environmental hygiene, disinfection, cleaning, process water treatments and more.
Water purification chemicals used for boiler water are used to ensure maximum efficiency of the boilers as well as steam production where required. These special water purification chemicals have a range of functions including the inhibition of corrosion and scale formation, improves alkalinity, treats condensate lines, conditions sludge and much more.
Closed circuit water systems employ water purification chemicals to improve the efficiency of a closed circuit system which can include the use of seawater, chillers, heaters, low pressure systems and other systems which require the system to remain closed for optimum functioning. These systems use water purification chemicals to remove contaminants, inhibit corrosion, antifoulants, scale inhibitors, de-icing and anti-freeze products as well as chemicals for frost or extreme heat protection.
Cooling Towers often employ the use of specific water purification chemicals to enhance the cleaning process, disinfecting and removing inorganic scale as well as specific biocides where required. Other chemicals may include biodispersants, water softeners, water hardeners as well as corrosion and scale inhibitors.
Some of the treatments even employ the use of micro-organisms which are biodegradable, safe and completely non-hazardous to people or the environment. These are often used in wastewater filtration systems, aquaculture as well as some industrial and manufacturing plants. Other chemicals you may come across in water treatments are acid and alkalinity builders, de-chlorinators, heavy metal precipitants, fuel-oil conditioners and more. Potable water treatments can include scale and corrosion inhibitors, biocides, odour removal, disinfectants and so forth to ensure the water is safe to drink.
Reverse osmosis is used to remove salts from water and purify it, either for drinking or to return to a specific system. These can include membrane cleaners, scale inhibitors and removers, detergents, cleaners, corrosion inhibitors, biocides, de-chlorinators, antifoulants and flocculants. This process is designed to assist with efficiency in operations of various industrial and manufacturing companies as well as reduce the number of issues usually encountered due to corrosion, lime scale and so forth. There are many other chemicals and processes used in order to keep systems functional or improve the overall quality of water in a specific system.
