Water treatment is a process for treating sewage or modern wastewater and converting it into more acceptable form for a specific end-use. The end utilization of this treated water might be drinking, mechanical water supply, water system, waterway stream support, water diversion or numerous different uses, including being securely returned to nature. Water treatment expels contaminants and undesirable parts, or diminishes their fixation with the goal that the water ends up noticeably fit for its coveted end-utilize. WATER TREATMENT includes four fundamental procedures which are boiler water treatment, cooling water treatment, water purification and treatment of wastewater effluent. This operation involves both physical and chemical modification of waste water. The chemicals which are employed for treating waste water are termed as waste water chemicals. Water Treatment Chemicals have been classified mainly on the basis of their application areas:-
Boiler Water Chemicals
Industrial boilers and steam raising plant are used extensively in many commercial, manufacturing and industrial processes. The main objective of boiler treatment chemicals is maintenance of boiler systems so that it functions appropriately. The main factors hindering boiler operation are scale formation, metallic corrosion, boiler water carryover and sludge deposition. Boiler water chemicals provide holistic solution to these problems. These include single-shot multifunctional treatment products, scale and corrosion inhibitors, oxygen scavengers, alkalinity builders, sludge conditioners, condensate line treatments and more.
Cooling Water Treatment Chemicals
Water is utilized broadly as an exceptionally proficient coolant in numerous industries where cooling is required. To guarantee such cooling frameworks are effectively kept up and work at ideal proficiency it is essential that the right cooling water conditions are set up and after that kept up constantly. The chemicals which help in accomplishing these conditions are termed as cooling tower chemicals. Chemicals for cooling water treatment includes highly effective biodispersants, corrosion inhibitors for both hard and soft water, and advanced multi-functional scale and corrosion inhibitor formulations, oxidizing and non-oxidizing biocide to control microbial growth and alagae blooms in re-circulating water.
Reverse Osmosis Chemicals
Reverse osmosis, regularly abbreviated as RO is a membrane filtration process that is used extensively for the desalination and purification of water. RO chemicals make sure that reverse osmosis plants and desalination plants are operated at peak execution. Advanced formulations of RO chemicals helps in upgrading operational efficiency of RO membrane. It has turned out to be beneficial in optimizing membrane life expectancy and in reducing total costs. RO membrane cleaners and detergents, scale inhibitors and antiscalants, corrosion inhibitors, biocides, antifoulants, de-chlorinators and flocculants are the chemicals listed under RO chemicals products.
Wastewater Treatment Chemicals
Waste water treatment chemicals mainly include coagulants and flocculants. Coagulants basically work for essential settling of suspended solids in effluent water and flocculants cause secondary setlling of particles. Alum (Ferric/Non-Ferric), Ferrous Sulfate, Ferric Chloride, PAC (Poly Aluminum Chloride) is mainly used as coagulants. Flocculation is accomplished with Polyelectrolytes, for example, Polyacrylamides (Anionic, Cationic and Non-ionic), Polyamine, PolyDADMAC and so on. Coagulants Flocullants are used for clarification,floatation and sludge dewatering of pharma and biotech wastes.
