Poly Aluminium Chloride( PAC)  in all form, is extensively used as an industrial coagulant and Flocculant in different industries. Different grades of PAC are available for different purposes. PAC products are used in water treatment for removal of suspended solid (Turbidity) and other contaminants such as natural organic matter from surface water, Micro – organisms and colloidal particles, silt and clay are stabilized by surface electrostatic charges preventing the particles from coalescing. It is advantageous in water of low to moderate turbidity, possibly because of the greater charge neutralizing capacity relative to alum.

Water treatment agents are chemicals or substances used to improve the quality of water by treating and addressing various issues such as contamination, impurities, odors, discoloration, and harmful microorganisms. Here are some common applications of water treatment agents:

01. Drinking Water Treatment

Water treatment agents are widely used in municipal water treatment facilities to purify and disinfect drinking water. They can remove contaminants such as bacteria, viruses, parasites, and chemicals, making the water safe for consumption.

02. Industrial Water Treatment

Industries use water treatment agents to treat water used in industrial processes. This helps prevent corrosion in equipment, control scaling and fouling, remove heavy metals and pollutants, and improve overall water quality.

03. Wastewater Treatment

Water treatment agents play a crucial role in treating wastewater before it is released back into the environment. They aid in removing organic matter, suspended solids, nutrients (such as nitrogen and phosphorus), and harmful substances present in wastewater.

04. Cooling Tower Treatment

Cooling towers are used in industrial systems to remove excess heat from processes. Water treatment agents are used to prevent scaling, corrosion, and microbial growth within the cooling towers and associated systems, ensuring efficient and reliable operation.

05. Boiler Water Treatment

In boilers, water treatment agents are used to prevent scaling, corrosion, and fouling. These agents help maintain the efficiency and longevity of the boiler by controlling dissolved solids, pH levels, and oxygen content in the water.

06. Swimming Pool and Spa Treatment

Water treatment agents, such as disinfectants (chlorine or bromine) and pH adjusters, are commonly used in swimming pools and spas to maintain water quality, kill harmful bacteria and viruses, and prevent algae growth.

07. Agricultural Water Treatment

Water treatment agents can be applied in agricultural settings to address water quality issues, such as high salinity, pathogens, and organic contaminants. They help ensure the water used for irrigation is suitable for crop production and minimize the risk of plant diseases.

06. Point-of-Use Water Treatment

Water treatment agents, such as activated carbon filters and disinfectant tablets, are used for point-of-use treatment in households and in remote locations where access to clean water is limited. These agents help remove impurities and make the water safe for drinking and other purposes.

It’s important to note that specific water treatment agents and methods may vary depending on the specific water quality issues and treatment goals. Consulting with WPA is recommended to determine the most suitable water treatment agents and approaches for each application.
