Polyacrylamide (PAM) for water treatment

Polyacrylamide Application：

Municipal wastewater treatment

More than 90% of urban sewage is water, and the rest is solid material. They generally contain suspended solids, pathogens (including bacteria, parasites, and viruses), organic matter, and phytonutrients (nitrogen and phosphorus). Depending on the source of pollution, urban sewage may also contain a variety of inorganic pollutants and organic pollutants. PAM chemical is mainly used in the settling gas flotation process and the sludge removal process in water treatment applications.

Sugar industry treatment process

PAM application for sugar cane refining in three main aspects:

• Sugarcane juice clarification: about 105℃， bagasse precipitation-filter cake,14-20 Brix.

• Syrup concentration: 85-90℃， so that the syrup is concentrated to 65Brix

• Sewage treatment: squeezer / generator cooling water, equipment cleaning/ floor cleaning/ boiler dust removal waste water, evaporation/crystallization condensate, etc.

Paper industry waste water treatment process

Polyacrylamide is mainly used in the treatment of papermaking wastewater in the sedimentation tank, air flotation tank, and advanced treatment. Generally, inorganic flocculants are used in combination with polyacrylamide. The sedimentation tank is mostly used with anions, and the air flotation tank is mostly used with cations.

Dyeing plant treatment process

It is recommended to use medium molecular weight and medium or low charge cationic PAM. It should be combined with other products (coagulant) to do the dying of plant waste water treatment.
