Water Treatment and Chemicals

PGA Engineering Co., Ltd. focuses on water treatment packages and conditioning chemicals for more than 15 years, and we are driving innovations to make our chemicals better applied to circulating water system, boiler and heating water system in fields such as steel & iron, paper making, petroleum, printing and dyeing, power plant, medical industries and etc.

Our chemicals category includes:

Scale Inhibitors, Corrosion Inhibitors, Chelating Agents, Polymers and Dispersants, Biocide and Algicide, Oxygen Scavenger, RO Membrane Chemicals and other Cleaning Agents, which cover wide ranges from single to complex agents.

Industrial wastewater treatment

Industrial wastewater treatment covers the mechanisms and processes used to treat wastewater that is produced as a by-product of industrial or commercial activities. After treatment, the treated industrial wastewater (or effluent) may be reused or released to a sanitary sewer or to a surface water in the environment. Most industries produce some wastewater although recent trends in the developed world have been to minimize such production or recycle such wastewater within the production process. However, many industries remain dependent on processes that produce wastewaters.

Boiler water treatment

Boiler water treatment is a type of industrial water treatment focused on removal or chemical modification of substances potentially damaging to the boiler. Varying types of treatment are used at different locations to avoid scale, corrosion, or foaming. External treatment of raw water supplies intended for use within a boiler is focused on removal of impurities before they reach the boiler. Internal treatment within the boiler is focused on limiting the tendency of water to dissolve the boiler, and maintaining impurities in forms least likely to cause trouble before they can be removed from the boiler in boiler blowdown.

Cooling water treatment

Besides treating the circulating cooling water in large industrial cooling tower systems to minimize scaling and fouling, the water should be filtered to remove particulates, and also be dosed with biocides and algaecides to prevent growths that could interfere with the continuous flow of the water. Under certain conditions, a biofilm of micro-organisms such as bacteria, fungi and algae can grow very rapidly in the cooling water, and can reduce the heat transfer efficiency of the cooling tower. Biofilm can be reduced or prevented by using chlorine or other chemicals.

Physical Treatment
