The waste water of sand washing plant refers to the waste water produced by sand washing enterprises in the production process. The main pollution factors of these wastes are chemical oxygen demand and suspended solids. If the production waste water is not treated timely and effectively, it will not only waste a large amount of water resources, pollute the water quality, affect the road traffic, and affect the normal production and life of nearby residents.
Usually, anionic polyacrylamide water purifier is used to treat sand washing wastewater. The treatment of sand washing wastewater is actually the separation of mud and water. The water obtained after separation is recycled and reused in the sand washing. Anions are commonly used to separate mud by flocculating sedimentation.
Anionic polyacrylamide is a water-soluble polymer. Because it contains a certain number of polar groups in its molecular chain, it can bridge the particles by adsorption of solid particles suspended in water or coagulate the particles through charge neutralization to form large flocculants. Mainly used for all kinds of industrial wastewater flocculation settlement, precipitation clarification treatment, can also be used for drinking water clarification and purification treatment. The effect of anionic polyacrylamide and inorganic flocculant polyaluminum chloride is better.
Polyacrylamide (PAM) is a linear polymer, chemical formula is (C3H5NO) N. It is a hard glassy solid at room temperature. The products are liquid glue, latex and white powder particles, translucent beads and flakes. Good thermal stability. Can be dissolved in water in any proportion, aqueous solution is uniform transparent liquid. After long-term storage, the solution viscosity will decrease due to slow degradation of polymer, especially when the storage conditions are poor.  Polyacrylamide, as lubricant, suspension agent, clay stabilizer, oil displacement agent, water loss reducer and thickener, has been widely used in drilling, acidification, fracturing, water plugging, cementing and secondary oil recovery, tertiary oil recovery. It is a very important oil field chemical.Learn more
Polyferric sulfate is a kind of inorganic polymer coagulant with superior performance. It is a light yellow amorphous powdery solid and easily soluble in water. 10% (mass) aqueous solution is red-brown transparent solution and hygroscopic. Polyferric sulfate is widely used in drinking water, industrial water, all kinds of industrial waste water, municipal sewage, sludge dewatering purification treatment.Learn more
