Distillery in the process of brewing will produce a lot of wastewater, the sewage mainly consists of yellow water and pot water, if not treated discharge will pollute the environment。
Distillery sewage needs to be treated to discharge, then distillery sewage need to add what agents to treat it?
Distillery sewage will generally use polyacrylamide to treat sewage.
The use of polyacrylamide is focused on the initial sedimentation tank stage. General use of polyaluminum chloride + anionic polyacrylamide use, so that impurities in the water can be physically precipitated, so that the water is clear.
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
