Flocculants gather the destabilized particles together and cause them to agglomerate and drop out of solution.


Coagulants are used to increase the size of aquatic substances, making them large enough to settle or to be removed by sand, dual layer filtration, or the membrane.

Organic Coagulants

Organic coagulation is more appropriate for solid-liquid separation. Organic coagulant is generally used when a reduction in sludge generation is desired

Polyamine and Polydadmac

Polyamine and Polydadmac are the most widely used classes of organic coagulation chemicals. They function by charge neutralization alone, Polyamines will generally treat higher turbidity raw water (approximately >20 NTU) effectively. Polyamines are also effective in treating many types of wastewater. PolyDADMACs are a specific class of polyamines that fit in this category.
