What is nonionic powder flocculants / polyacrylamides (ndpam)?

Nonionic powder flocculants can be produced with very high molecular weights, giving it the capability to form large, rapid-settling, good-compacting flocs. We produce nonionic powder flocculants / polyacrylamides (NDPAM) in a standard range plus in high and low molecular weights.

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.

What is flocculant in chemistry?

It is used to describe the action of polymeric materials which form bridges between individual particles. Bridging occurs when segments of a polymer chain adsorb on different particles and help particles aggregate.flocculant carrys active groups with a charge which will counterbalance the charge of the particles.

What are polymers used in flocculation?

Polymers are chemicals used in flocculation. Flocculation is the process of agglomerating destabilized particles into bigger flocs. In wastewater flocculation and sludge treatment, colloidal particles are flocked in order to aid their removal or to help sludge dewatering.

What are the types of industrial polyacrylamides?

The types of flocculants, in other words industrial polyacrylamides, are cationic, anionic or nonionic polyacrylamides. Kemira’s polyacrylamides of wide range of charge and molecular weight are sold in dry powder or emulsion format and have excellent performance.

What are anionic polyacrylamides used for?

Anionic polyacrylamides are used, among other things, for water clarification and process water recycling. Anionic polyacrylamides are easier to polymerize to very high molecular weights. We produce anionic powder flocculants / polyacrylamides (ADPAM) with anionic charge density ranging from 0-100%.
