How anionic Polyacrylamide is used in industrial wastewater treatment?

Industrial wastewater treatment Anionic polyacrylamide has good effect on the treatment of wastewater with suspended particles ,high concentration, positive charge and neutral or alkaline pH value, steel plant wastewater, electroplating plant wastewater, metallurgical wastewater, coal washing wastewater and other wastewater.

What is the effect of cationic polyacrylamide?

The effect of cationic polyacrylamide is several times or tens of times higher than that of anionic, non-ionic polyacrylamide or inorganic salt, because this kind of wastewater generally has negative charge. 2. Application of anionic polyacrylamide (1). Industrial wastewater treatment

Is polyacrylamide ionic or cationic?

Due to its excellent flocculation, thickening, and enhancing properties, polyacrylamide is widely used in various industrial fields such as water treatment, paper making, petroleum, coal, and mining metallurgy. Based on its ionic characteristics, polyacrylamide is mainly divided into three categories: anionic, cationic, and non-ionic.

What is polyacrylamide used for?

Polyacrylamide has effects of flocculation, thickening, drag reduction, adhesive, colloidal stabilizing, filming and preventing scale. It is widely used in papermaking, mining, coal washing, metallurgy, oil exploitation and other industrial sectors and is also a important chemical for water treatment. Figure 1 The synthetic route of polyacrylamide.

How cationic polyacrylamide is used in sludge dewatering?

Cationic polyacrylamide can effectively remove these contaminants through charge neutralization and bridging effects. Additionally, cationic polyacrylamide is widely used in the sludge dewatering process to improve dewatering efficiency and reduce the water content of the filter cake.

Can nonionic polyacrylamide be used as a sewage treatment agent?

Nonionic polyacrylamide can be used as a sewage treatment agent for acidic slurry, making the suspended particles flocculate and precipitate. * You have to Login or Register to download this file.
