There are so many models of polyacrylamide, how should I choose?
According to the ionic type, polyacrylamide can be divided into cationic polyacrylamide, anionic polyacrylamide, and nonionic polyacrylamide.
Among them, cationic polyacrylamide is mainly used in the solid-liquid separation process in industry, including sedimentation, clarification, concentration and sludge dehydration. The main industries used are: urban sewage treatment, paper industry, food processing industry, petrochemical industry, metallurgy, etc. Wastewater treatment in industry, mineral processing industry, dyeing industry and sugar industry and various industries.
The role of anionic polyacrylamide is to use the charge on its molecules to be opposite to that of the sludge particles, and to neutralize the positive and negative charges to destabilize it. Using the long chain effect of its polymer, many fine sludge particles are adsorbed and entangled together to form larger particles. Generally, it has the following functions: sludge dehydration, clarification and purification, sedimentation promotion, filtration promotion, thickening and other functions. It is used in the following fields: sewage flocculation and sedimentation treatment, sludge dehydration and pressure filtration treatment, additive thickening treatment, sand washing, shield tunneling and construction mud treatment, petroleum industry treatment, river dredging treatment, mineral processing production treatment, etc.
When selecting a polyacrylamide product model, you can contact the manufacturer to confirm the required polyacrylamide product model through the industry you are in, or you can confirm the model through sample testing.
