Cationic polyacrylamide is used in sewage treatment. It is a polymer organic flocculant and is widely used in industrial enterprises. Currently, in the industrial industry, most of them are used in the sewage treatment industry, because organic flocculants are in acidic or alkaline media, and the positive properties of cations can quickly and effectively flocculate and precipitate sewage.
Application of cationic polyacrylamide in wastewater treatment
Powdered polyacrylamide is often used in organic wastewater, usually to flocculate and settle the negatively charged sewage with suspended particles in the sewage. According to the cationic acidic or alkaline medium in the flocculation device, relying on the presentation of positive electricity is extremely effective for rapid clarification of sewage. In addition to powdered polyacrylamide, polyaluminum chloride and anionic polyacrylamide moldings are also increasingly used in organic wastewater treatment.

Engineering treatment of alcohol factory wastewater, brewery wastewater, MSG factory wastewater, sugar factory wastewater, meat product factory wastewater, beverage factory wastewater, textile printing and dyeing plants and various sewage plants The wastewater contains various organic solvents, inorganic and organic sulfides, hydrocarbons, chlorine, oil, mercury and other environmentally harmful components. It can be flocculated with polyacrylamide before being discharged. It can also be used as a mud treatment agent in the oil field development process, a selective water blocking agent, a water injection thickener, a softener in the textile printing and dyeing process, an antistatic agent and a general sterilization and disinfectant.
Cationic polyacrylamide is used for water purification, water
oil system demulsification, oily wastewater treatment, wastewater recycling and sludge dehydration. Polyacrylamide can effectively reduce the frictional resistance of fluids. Adding a trace amount of polyacrylamide to water can reduce resistance
