Effects of lowering temperature on process parameters of sewage treatment plants Decreased sludge activity: Low temperature will significantly inhibit the metabolic activity of microorganisms, resulting in poor sludge settling performance, slowed biochemical reaction rates, and reduced organic matter removal efficiency. Changes in dissolved oxygen demand: Due to the weakening of microbial metabolic activity, the demand …

There are many polyacrylamide models, and the molecular weight of each model is also different, some products can reach more than 10 million molecular weight, and some products have only a few million molecular weight. The molecular weight of the cationic polyacrylamide is lower than the molecular weight of the anion, then how to determine …
