Anionic
Polyacrylamide (APAM)
The PAM products are used in various industrial waste treatments as
coagulants and flocculants. The main fields involve:
Beer industry/pharmaceutical industry/papermaking industry/Mining
industry/Petrochemistry industry/Textile printing and Dyeing/Chemical
industry/Food processing industry/Waste water (containing oil) treatment industry,etc.
Wastewater treatment is necessary in many kinds of industrial fields,
the selection of Polyacrylamide varies according to the type of wastewater, and
the treatment process.
In the primary waster treatment(floation or sediment),we use a
combination of inorganic additive and flocculant. In some specific cases, We
must adjust the PH in order to obtain a better result.
In the last step of dewatering process, the use of one kind of organic
flocculent is enough to meet the needs. Most used products are cationic
Polyacrylamide. Only in some specials cases, anionic Polyacrylamide are used. The
products will be chosen according to each process by technicians.
