Polyacrylamide in Water Treatment - Sinofloc Chemical
The use of sewage flocculants will use of cationic polyacrylamide as a sludge dewatering agent. 2, polyacrylamide ion degree choice: for the dewatering sludge, can be different degrees of flocculants through a small experiment to select the best suitable polyacrylamide, so that you can get the best flocculants effect, But also to minimize the amount of drugs, cost savings.Get Price

The Use of Cationic Polymers as Primary Coagulants in Water
Similar results were obtained for a river water, where a cationic polyacrylamide (CPAM) of high charge was also effective. Chitosan performed reasonably for both waters, despite low charge and MW. Weakly basic polymers could be binding NOM via hydrogen bonding to free amino groups. Organic polymers generally did nearly as well as alum for both waters, taking out 86–100% of the colour that alum does, and performing even better when other particulates were present. Mixtures of alum andGet Price
The use of cationic, anionic and nonionic polyacrylamide
Drinking water treatment: many Chinese waterworks water from rivers, sediment and mineral content is high, compared with turbidity, although after precipitation and filtration, still can not meet the requirements and need to adding flocculant, dosage is 1 / 50 of the inorganic flocculant, but the effect is several times the inorganic flocculant for the organic polluted river water, using inorganic flocculants and company of cationic polyacrylamide with better effect to use can be.

Cationic Polyacrylamide Flocculant/ Powder - Sinofloc Supplier
If the impurities in the water particles larger, and with a certain charge, then the treatment performance of cationic polyacrylamide alone sometimes is good. If the impurities particles are small and non-charged, then it shall be added inorganic flocculants first and then add cationic polyacrylamide powder. An experiment is usually taken before answer this question. Without adding inorganic flocculants, add polyacrylamide directly to see if the impurities in the water flocculation can beGet Price

Properties of Polyacrylamides
One of its largest uses is waste water treatment. When added to waste water, it causes suspended particles to aggregate and to precipitate. In municipal and industrial waste water treatment it can be used in all liquid-solid separation processes including primary sewage treatment. PAMs are also used to treat water from mineral mining operations. Another common use is oil extraction and recovery. When water is injected into the well, PAM assists in pushing oil locked in reservoirs towards theGet Price
