Dewatering Cationic Polyacrylamide Flocculant Granular For Municipal Sewage Sludge

Cationic Polyacrylamide Flocuclant For Dewatering Of Municipal Sewage Sludge​​

Cationic polyacrylamide PAM is a high molecular polymer. Because it has a variety of active groups, it can have affinity with a variety of substances and form hydrogen bonds through adsorption. Mainly used for flocculation of negatively charged colloids. It has the functions of removing turbidity, decolorization, adsorption and attachment. It is suitable for printing and dyeing, papermaking, food, construction, metallurgy, mineral processing, coal powder, oil field, aquatic product processing, fermentation and other industries. High wastewater treatment, especially suitable for dewatering treatment of industrial sludge such as urban sewage, urban sludge, and paper sludge.

Different flocculants are used for municipal sewage according to different treatment methods. If the main body of the process adopts the biochemical method, that is, the dewatering of the excess sludge (which may contain part of the primary sludge), only cationic polyacrylamide flocculant is needed as the sludge dewatering agent. If the main body of the process adopts physicochemical methods, such as primary strengthening, loading magnetic separation, etc., generally, polyaluminum chloride is first added for conditioning, then anionic polyacrylamide is added, and then cationic polyacrylamide flocculant is added for dehydration. The specific dosage depends on Depends on the quality of the sewage.

Cationci Polyacrylamide flocculant application field

1 For sludge dewatering, CPAM products of the corresponding brand can be selected according to the nature of the sludge, which can effectively dewater the sludge before it enters the filter press. The mud cake is loose and thick, the dehydration efficiency is high, and the water content of the mud cake is below 80%.

2 For the treatment of domestic sewage and organic wastewater, the cationic polyacrylamide product exhibits a positive charge in a complex or alkaline medium, which makes the negatively charged sewage and the suspended particles in the sewage flocculate and settle, which is very effective for the treatment of sewage. Clarify. For example, 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., use cationic polyacrylamide than anionic polyacrylamide The effect is good, and 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.

3 Flocculant is used to treat tap water with river water as the source of water, with low dosage, good effect and low cost, especially when used in conjunction with inorganic flocculant to treat tap water in other basins of the Yangtze River and Yellow River. High-efficiency flocculant for plants.
