Water treatment is the process of treating water to make it suitable for an end-use, which may be reuse, drinking, industry, medicine, or discharge. Various types of water such as sea water, ground water, municipal drinking water, makeup and process water, and industrial waste water can be treated using different types of chemicals to achieve a specific result. Our keys areas of focus in this large, highly diverse, and complex space, include the following:
Pretreatment consists of treatment of makeup water for use in an industrial system. Methods utilized in pretreatment include membrane and filtration systems operations (generally using carbon filters, birm, sand filters, microfiltration, ultrafiltration, multi-media filtration, and various others) and water softening (generally using demineralizers, dechlorinizers and ion exchangers).
Boiler Water Treatment
Boiler water treatment refers to treatment of raw water intended for use in boilers, boiler feedwater, steam condensate being returned to a boiler, or boiler blowdown being removed from a boiler. This type of water treatment is focused on removal or chemical modification of substances potentially damaging to the boiler and consists of varying types of treatment used at different locations to avoid scale, corrosion, or foaming. Scale deposition and corrosion can be seriously problematical when it comes to the function of a boiler system. They can significantly reduce a system’s efficiency, and compromise a boiler’s reliability. To ensure that boiler systems are correctly maintained and operate at optimum efficiency, it is essential to regularly treat the water with certain chemicals. Boiler water chemicals include single-shot multifunctional treatment products, deposit and corrosion inhibitors, oxygen scavengers, descalers, alkalinity builders, condensate line treatments and more.
Cooling Water Treatment
Water is used extensively as a highly efficient coolant in many commercial, manufacturing and industrial process activities where cooling is required. The purpose of a cooling system is to remove heat from heat-producing equipment or processes, and water is the most common medium to transfer heat. As is the case with boiler systems, scale, corrosion, fouling and microbiological contamination can adversely affect the efficiency of a cooling system and hence ongoing water treatment of cooling systems is an integral part of process operations in many industries. Whether a cooling system is open-recirculating, closed-loop, or once-thru system, it is essential that the correct cooling water conditions are established and then maintained at all times. Cooling water treatment chemicals include dispersants, deposit and corrosion inhibitors for both hard and soft water, descalers, as well as biocides and algaecides.
Waste Water Treatment
Wastewater is produced as a by-product of industrial or commercial activities (such as in iron and steel industry, food industry, pulp and paper industry, chemical manufacturing, and many others). Treated industrial wastewater (or effluent) may be reused or released to a sanitary sewer or to surface water in the environment. Chemicals used to treat wastewater include defoamers, emulsion breakers, anionic and cationic flocculants, biocides and disinfectants, neutralizing agents, heavy metal precipitants, sludge conditioners, odor control agents, cleaners, reducing agents, and filter aids.
