Most of our daily food contains starch, and the main raw material of starch production is some organic crops, so how to deal with the impurities and waste water after starch production?
Starch wastewater mainly comes from raw material treatment, soaking, crushing, screening, starch separation, washing and drying.Starch wastewater contains a lot of soluble organic pollutants, some inorganic compounds, and a certain amount of volatile acids and ash.
Most of the sewage produced by starch manufacturers need to go through the corresponding sewage treatment before discharge, commonly used agents are polyacrylamide, polyaluminum chloride and so on.
Cationic polyacrylamide (CPAM) is a linear polymer compound, because it has a variety of active groups, and many substances affinity, adsorption form hydrogen bonds. Mainly flocculating negatively charged colloid, with turbidity removal, decolorization, adsorption, adhesion and other functions, suitable for dyeing, papermaking, food, construction, metallurgy, mineral processing, coal powder, oil fields, aquatic products processing and fermentation industries organic colloid content is higher wastewater treatment, especially suitable for urban sewage, urban sludge, paper sludge and other industrial sludge dehydration treatment.
