Classification of polyacrylamide

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 …

What is micro-electrolysis suitable for?

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 …

5 major misunderstandings in the selection of polyacrylamide (PAM)

5 major misunderstandings in the selection of polyacrylamide (PAM) 1: The larger the molecular weight, the better the effect Many users mistakenly believe that the higher the molecular weight of PAM, the better the flocculation efficiency and treatment effect. However, in fact, the best flocculation effect under different water quality conditions may correspond to a …

How to accurately select the type of PAM flocculant in sewage treatment?

How to accurately select the type of PAM flocculant in sewage treatment? Suspended solids (SS) and turbidity: For sewage containing a large number of fine, difficult-to-sediment suspended particles, high molecular weight, high hydrolysis degree anionic PAM should be selected, because it has good bridging adsorption and net capture effects, and can effectively condense and precipitate …
