PAM Cationic Polyacrylamide Flocculant Polymer Coagulant For Water Treatment

Cationic Polyacrylamide Flocculant Coagulant Polymer CPAM Sewage Purifying Agent​

Cationic polyacrylamide (CPAM) is white powder in appearance and is a linear polymer compound. Because it has a variety of active groups, it can interact with a variety of substances and adsorb to form hydrogen bonds. The molecular weight ranges from 3 million to 12 million. The ion degree ranges from 10% to 60%. Good water solubility, soluble in water in any proportion, insoluble in organic solvents. The effective PH value ranges from 1 to 14. It has the characteristics of polymer electrolyte and is suitable for the treatment of negatively charged and organic-rich waste water.

For sludge dewatering, the corresponding type of cationic polyacrylamide can be selected according to the nature of the sludge, which can effectively dewater the sludge before it enters the filter press. Large flocs are produced during dehydration, which do not stick to the filter cloth and do not spread during the filter press process. The mud cake is thicker and the dehydration efficiency is high. The water content of the mud cake is below 80%.

For the treatment of domestic sewage and organic wastewater, cationic polyacrylamide presents a positive charge in an acidic or alkaline medium, which makes it flocculate and settle with negatively charged suspended particles in the sewage, which is very effective for clarification. For example, in the production of grain alcohol wastewater, papermaking wastewater, municipal sewage treatment plant wastewater, beer wastewater, monosodium glutamate factory wastewater, sugar refining wastewater, high organic matter wastewater, feed wastewater, textile printing and dyeing wastewater, etc., it is better to use cationic polyacrylamide than anion. The effect of non-ionic polyacrylamide or inorganic salt is several or several tens of times, because this kind of waste water is generally negatively charged.
