Can cationic polyacrylamide be used for sludge treatment?

In general, cationic polyacrylamide for the treatment of organic sludge, anionic polyacrylamide for the treatment of inorganic sludge, alkaline is very easy to use cationic polyacrylamide, and acidity should not use anionic polyacrylamide, when the solid content of mud is high, the amount of polyacrylamide is usually large.

Can sewage flocculants use cationic polyacrylamide as a sludge dewatering agent?

The use of sewage flocculants will use of cationic polyacrylamide as a sludge dewatering agent.

Which type of polyacrylamide is best for sludge dewatering?

Cationic PAM with weak ionicity is the best for sludge dewatering and is used in paper-making and dyeing industries. The one with strong ionicity is used in the treatment of medical wastewater. Different aspects can help you choose the right type of polyacrylamide. Aspects you should look out for include:

What is cationic polyacrylamide used for?

Cationic polyacrylamides are used, among other things, for the dewatering of sludge from biological treatment processes. Typically, the higher the share of biological sludge in the total amount of sludge, the higher the cationic charge density required in the polymer.

How much cationic polymer should be used in wastewater sludge?

The polymer dosage is commonly based on the active polymer content of the made-up polymer solution and on the dry-solids (DS) content of the sludge. The dosage for an average cationic PAM for digested wastewater sludge can range from 5 to 15 kg active polymer per tonne DS [kg/t DS].

Does Kemira produce cationic dry powder flocculants / polyacrylamides?

Kemira produces a full range of cationic dry powder flocculants / polyacrylamides (CDPAM) in a range of molecular weights. We also offer a full range of cationic inverse emulsion (CEPAM) flocculants of different cationic charge densities and molecular weight variants.
