Classification of polyacrylamide Polyacrylamide can be divided into nonionic, anionic and cationic polyacrylamide. Non-ionic: (NPAM), neutral, uncharged. ① Neutral or acidic sewage is more commonly used, such as mineral processing wastewater, stone factories, engineering mud, and printing and dyeing factories. ② The flocculation effect mainly relies on a large number of molecular groups on the …
Micro-electrolysis technology is currently an ideal process for treating high-concentration organic wastewater, also known as internal electrolysis. In a nutshell, it uses the 1.2V potential difference generated by the micro-electrolysis material filled in the wastewater to electrolyze the wastewater without electricity, so as to achieve the purpose of degrading organic pollutants. When the system is …
