Pam Chemical Water Treatment Sludge Dewatering Flocculant Cationic Polyacrylamide

Cationic polyacrylamide (CPAM) 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. Mainly used for flocculating negatively charged colloids, with functions of turbidity removal, decolorization, adsorption, adhesion, etc., suitable for dyeing, papermaking, food, construction, metallurgy, mineral processing, coal powder, oil field, aquatic product processing and fermentation industries. The treatment of wastewater with high organic colloid content is especially suitable for the dehydration treatment of industrial sludge such as municipal sewage, municipal sludge, and papermaking sludge.

Because cationic polyacrylamide has the following functions:

1. Clarification and purification;
2. Settlement promotion effect;
3. Filtration promotion effect;
4. Thickening effect and other functions.
Therefore, it can fully meet the requirements in waste liquid treatment, sludge concentration and dewatering, beneficiation, coal washing, papermaking, etc.

♦ For sludge dewatering, the corresponding model of cationic polyacrylamide can be selected according to the nature of the sludge, which can effectively dewater the sludge before the sludge enters the filter press. When dewatering, it produces large flocs, does not stick to the filter cloth, and does not disperse during the filter press. , The mud cake is thicker, the dehydration efficiency is high, and the water content of the mud cake is below 80%.

♦ It is used for the treatment of domestic sewage and organic wastewater. It flocculates and settles the suspended particles in the sewage with negatively charged sewage, and the clarification is very effective. For example, the production of grain alcohol wastewater, papermaking wastewater, municipal sewage treatment plant wastewater, beer wastewater, monosodium glutamate factory wastewater, sugar wastewater, high organic content wastewater, feed wastewater, textile printing and dyeing wastewater, etc., the use of cationic polyacrylamide is better than the use of anion, The effect of non-ionic polyacrylamide or inorganic salts is several times or tens of times higher, because this kind of waste water is generally negatively charged.
