In today's increasingly deteriorating environment, polyacrylamide, as a water disposal flocculant, has made great contributions to China's water environment management. It is the best choice for many occupations to manage sewage. Polyacrylamide is commonly used as water source Is polyacrylamide suitable for cleaning, papermaking, textiles and other occupations?
Special polyacrylamide for sand washing field, anionic polyacrylamide is usually selected as sand washing flocculant. Anionic polyacrylamide is a water-soluble polymer. Because its molecular chain contains a certain number of polar groups, it can absorb solid particles suspended in water, bridge the particles or neutralize the charges to agglomerate the particles to form large flocs. It is mainly used for the flocculation and sedimentation of various industrial wastewater, such as iron and steel plant wastewater, sand washing wastewater, electroplating plant wastewater, coal washing wastewater and other sewage treatment, sludge dewatering, etc. It can also be used for clarification and purification of drinking water. At the same time, using anionic polyacrylamide products and inorganic flocculant polyaluminum chloride, etc., have a better effect.
If the sand and mud flow washed by the sand washing plant is directly discharged, this kind of sewage will seriously pollute the river water because of the extremely high silt and sand content, and cause great pollution to the environment, but it cannot be without a sand washing plant, because today’s life Health plants are all interlocking and indispensable. Therefore, the use of flocculants to effectively dispose of waste water from sand washing plants has become a top priority!
Anionic polyacrylamide can achieve a very good effect, and its water solubility is good, in the case of using a little amount, you can see an obvious effect, usually only an increase of 0.01~10ppm (0.01~10g/m3)! The sand and mud flow of the sand washing plant, this kind of sewage will severely pollute the river water because of the extremely high mud and sand content, and cause great pollution to the environment. Anionic polyacrylamide can successfully treat waste water from sand washing plants, and its water solubility is good, and it can achieve very good results, usually only an increase of 0.01~10ppm (0.01~10g/m3). Polyacrylamide is a clean water flocculant commonly used in water treatment plants, and can be used in water companies, sewage treatment plants, power plants, paper mills, printing and dyeing plants, textile plants, steel plants, oil refineries, and chemical plants. The sand and gravel plant washes the sand, then separates the sand from the water, recovers the water and reuses it to wash the sand.
