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 …

There are two main types of flocculants used in the treatment of coal mine wastewater: inorganic flocculants and organic flocculants. In coal mine coal washing and wastewater treatment, polyacrylamide (PAM) is one of the most common types of organic flocculants. The following is a specific classification and its application in coal mine wastewater treatment: 1. …
