Long-chain polymer flocculants, such as modified polyacrylamides, are manufactured and sold by flocculant producers. These can be supplied in dry or liquid form for use in the flocculation process. The most common liquid polyacrylamide is supplied as an emulsion with 10-40% actives and the rest is a non-aqueous carrier fluid, surfactants and ...
Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2-). It has a linear-chain structure. It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated.
Polyacrylamide flocculants are used in the primary settlers as well as in the sludge dewatering stage. For industrial water treatment, SNF provides heavy metal chelatants, dispersants and scale inhibitors.
4x speed video of floc settling after adding flocculant polymers during a jar test. In colloidal chemistry , flocculation is a process by which colloidal particles come out of suspension to sediment in the form of floc or flake, either spontaneously or due to the addition of a clarifying agent .
Acrylamide (or acrylic amide) is an organic compound with the chemical formula CH 2 =CHC(O)NH 2.It is a white odorless solid, soluble in water and several organic solvents. From the chemistry perspective, acrylamide is a vinyl-substituted primary amide (CONH 2).

Anionic polyacrylamide (PAM), a synthetic petroleum by-product, is a flocculant that is applied as pellets or in solution to the soil surface in fire-affected areas. PAM binds soil particles, increase soil stability and infiltration, and reduce soil erosion.
Particle agglomeration can be induced by adding salts or other chemicals referred to as coagulant or flocculant. [1] Scheme of particle agglomeration. Particles are dispersed individually in a functionally stable suspension, while they agglomerate in a functionally unstable suspension.
