Polyacrylamide for pharmaceutical wastewater needs higher quality
Pharmaceutical factory wastewater is complex and special, high-quality polyacrylamide flocculant used mostly in sedimentation and dehydration treatment, not the general quality of polyacrylamide flocculant good suspension of impurities in the sewage flocculation up completely. Especially the use of sludge removal water cationic polyacrylamide, suggested using high quality imported cation. Among them, the cationic polyacrylamide imported from Hao Nuo has good effect on the dewatering of biochemical sludge in pharmaceutical factory.
In the treatment of sludge from pharmaceutical plants, cationic polyacrylamide is usually used. Why would you recommend manufacturers to use better cations? Because the effluent from the pharmaceutical factory is not only high in organic pollutants, but also contains a variety of factors that inhibit microbial growth. Only the better suspension of the suspended sediment in the sewage can be discharged.
For pharmaceutical wastewater, the cationic polyacrylamide product with higher ionic degree should be selected. If the concentration of organic ions is very high, the effect of ion degree more than 60 is best. If it is electrolytic treatment or previous air flotation treatment, according to the quality of sewage water, the key technical indicators are to see the pH value to determine the choice of polyacrylamide.
