The amide group of polyacrylamide can form hydrogen bonds through affinity and adsorption with many substances. Relatively high molecular weight polyacrylamide forms bridges between the adsorbed ions to form flocs and accelerate the sedimentation of particles. Compared with traditional inorganic flocculants, it has many varieties, can adapt to various conditions, small dosage, high efficiency, less sludge and easy post-treatment.

【Storage, transportation and precautions】 Polyacrylamide itself is not toxic. Only when the inhaled amount is greater than five thousandths, it is harmful because the absorption of nutrients by the gastrointestinal mucosa is blocked. Residual acrylamide monomers in water purification flocculants are toxic, and food applications should be strictly controlled. Storage and transportation should pay attention to moisture-proof.
【Package specification】Dry powder 25kg/bag, inner bag with PVC film, outer bag with kraft paper bag.

●Urban sewage treatment
In the first-stage treatment section of urban sewage, the sewage is usually pretreated by adding inorganic coagulants first, and then adding anionic polymers to improve the flocculation efficiency and reduce the content of tiny particles in the water body. In the activated sludge treatment section and the digested sludge treatment section, it is usually better to use medium and high power cations.
● Industrial sewage treatment Because industrial sewage involves many industries, the properties of industrial sewage in different industries are different. In general, cationic and Non-ionic sewage containing high organic matter or acidity, and a large amount of suspended solids or alkaline sewage are selected. Anionic and nonionic.

● Jianghe raw water treatment
The raw water of rivers contains a lot of suspended solids, so it should be pretreated with inorganic flocculants, and then flocculated by adding low-residue polyacrylamide products.
