Polyacrylamide for food processing wastewater treatment
In the process of food factory wastewater treatment, we first filter the large sediment in the wastewater with a grille, then the wastewater flows into the wastewater sedimentation tank,and the PH of the wastewater is adjusted to be neutral, so that its pll value reaches the range of 6-9. In the neutral range of water quality, the role of polyacrylamide can be maximized.There are many processes of wastewater treatment in food factories,large and small. We need to use polyaluminium chloride and polyacrylamide in the sewage precipitation stage to achieve the best sewage treatment effect.Aftera series of treatment processes,the final sewage is treated into clean water, and the impurities deposited at the bottom of the clean water tank need to be pressed by the filter press.Achieve the purpose of solid-liquid separation. In the process of sludge pressure filtration, if the direct pressure filtration is used, the effect may not be good, resulting in the phenomenon of mud escaping or high water content ofmud cake.In the sludge dewatering stage,we need to use polyacrylamide to modify the sludge.
