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 …

Polyacrylamide is a polymer compound with a linear or cross-linked structure that can be obtained by polymerization. It can form a high molecular weight aqueous solution when dissolved and has good fluidity and stability. The special properties of polyacrylamide make it play an important role in many fields. Application of environmental protection 1. Sewage treatment As an …

There are many methods for water treatment, such as adsorption, chemical oxidation, electrodialysis, biochemistry and ion exchange, etc. As one of the oldest water treatment methods, flocculation precipitation is a more effective and low-cost pretreatment method. Nowadays, it has been widely used in the field of water treatment at home and abroad. The principle of …
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 …
