Secco polyacrylamide for sewage treatment of sand washing plant

2022-12-19 17:58:52


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.
