We received one of our clients’ inquiries about the usage of polyacrylamide, mainly asking whether different ionic types of products can be mixed together? Polymersco agree that polyacrylamide products according to their molecular structure and functional monomers are very different in the application of the general situation is not mixed, such as cationic and anionic type if mixed them together, the effect will be greatly reduced, or even inefficient and lead to the final failure.
Polymersco agrees that In the field of water treatment, it is normal to use two or three products together, for example, inorganic flocculants represented by polymeric aluminum chloride are often required in the latter part of the process with anionic or cationic polyacrylamide, while in the field of municipal wastewater treatment, anionic polyacrylamide is sometimes used in the first stage of treatment, but cationic polyacrylamide is used in the sludge dewatering stage. Both are in different sections of the same system, so if the two products are added to a single process at the same time, the effect may not be worth the loss.
Some customers think that amphoteric polyacrylamide is anionic and cationic composite, polymerso here to make a relevant explanation, amphoteric polyacrylamide is not made products directly mixed together on the line, the product is made of cationic monomer, acrylamide monomer, hydrolysis agent terpolymer copolymer from the linear polymer, with good decolorization, adsorption, turbidity removal, bonding, and other functions. It has good decolorization, adsorption, turbidity removal, adhesion, and other functions. The product is an amphoteric irregular polymer with both cationic and anionic charges on the molecular chain.
In industrial applications, there are many polyacrylamide products with different specifications, but there is always one that is suitable for you, so polymersco recommends that the most economical solution is to find the corresponding one through selection.
