What is Cationic PAM?
Cationic polyacrylamide series products are linear high molecular polymers made of cationic monomers(DM, MDC, CPF, DMDAAC, DMAEMA, etc) and acrylamide copolymerized, granulated, dried, and crushed. With decolorization, adsorption, turbidity, adhesion, sludge dewatering, and other functions. Cationic polyacrylamide is mainly used for desliming. Different desliming equipments are suitable for cationic polyacrylamide with different ionic degrees.
Cationic polyacrylamide is mainly used to flocculate colloid with a negative charge, which has the functions of turbidity removal, decolorization, adsorption, adhesion, etc. it is suitable for wastewater treatment with high organic colloid content in dyeing, papermaking, food, construction, metallurgy, mineral processing, coal powder, oil field, aquatic products processing, and fermentation industries, especially for urban sewage, urban sludge, wastewater treatment and so on dewatering of paper sludge and other industrial sludge.
Polyacrylamide(PAM) has Anionic type, Cationic type and Nonionic type, which have many uses regarding to some industries.
1. Sludge dehydrating agent: activated sludge method is commonly used to treat urban and industrial sewage. Biochemical sludge is often a colloid with strong hydrophilicity and high organic content, which is extremely difficult to dehydrate. It is easy to separate because of its low dosage, high dehydration efficiency.
2. Papermaking additives: in the papermaking industry, it can directly produce an electrostatic bridging effect with inorganic salt ions, fibers, and other organic polymers, so as to enhance the physical strength of the paper, reduce the loss of fibers or fillers, speed up water filtration, and play the role of reinforcement, retention, and filtration. It can also be used for white water treatment, and can also play an obvious flocculation effect in the deinking process.
3.Treatment of sewage and organic wastewater: This product presents positive electricity in an acidic or alkaline medium, so it is very effective to flocculate and clarify the sewage with more suspended particles carrying a negative charge. Such as wastewater from alcohol factories, brewery, monosodium glutamate factory, sugar factory, meat factory, beverage factory, textile printing, and dyeing factory, etc. For this kind of wastewater, the effect of cationic polyacrylamide is several times or tens of times higher than that of anionic polyacrylamide, nonionic polyacrylamide, or inorganic salt.
4. Flocculant for water treatment in Waterworks with rivers as water source: less dosage, good effect, and low cost, especially when combined with inorganic flocculant
5. Oilfield chemicals: such as clay anti-swelling agent, thickening agent for oilfield acidizing, etc
