Cationic polyacrylamide has many advantages

2023-02-24 11:08:04


The efficacy of cationic polyacrylamide has been recognized both inside and outside the industry, especially in the flocculation precipitation of industrial wastewater. Because of its curative effect, this medicine is widely used. In sewage treatment, the treatment of colored sewage is relatively difficult.

First of all, let’s look at the treatment methods of nonferrous metal wastewater in the past. It is understood that before polyacrylamide was widely used, colored sewage was treated by activated carbon decolorization or other methods. However, cationic polyacrylamide is currently a common treatment agent for this type of sewage. Why use cationic polyacrylamide instead of other ionic polyacrylamide? The main reason is that cationic polyacrylamide is particularly excellent in flocculation and decolorization. Cationic polyacrylamide has good adsorption and bridging properties. Molecular chain extender properties can not only adsorb suspended matter, but also adsorb pigment in precipitated wastewater.

Compared with the decolorization effect of activated carbon, cationic polyacrylamide has many advantages. Only once can the chroma and suspended matter content of the wastewater meet recycling or discharge standards. This is also the reason why cationic polyacrylamide is more popular in the nonferrous wastewater treatment industry.
