PDadmac - DADMAC homopolymer product

PDADMAC is the most commonly used organic coagulants in water treatment. Coagulants neutralise the negative electrical charge on particles, which destabilises the forces keeping colloids apart. In water treatment, coagulation occurs when a coagulant is added to water to “destabilize” colloidal suspensions.This product (technically named Polydimethyl-Diallyl-Ammonium Chloride) is cationic polymer and it can be completely dissolved in water.

Polydiallydimethylammonium chloride (shortened PDADMAC or PolyDDA) is a homopolymer of diallydimethylammonium choride (DADMAC).
The molecular weight of polyDADMAC is typically in the range of hundreds of thousands of grams per mole, and event up to a million for some products. polyDADMAC is usually delivered as a liquid concentrate having a solids level in the range of 10 to 50%. It is a high charge density cationicpolymer.
The charge density makes it well suited for flocculation.

Properties
The polymer body contains strong cationic group radical and activated-adsorbent group radical which can destabilize and flocculate the suspended solids and the negative-charged water soluble matters in the waste water through electro-neutralization and bridging adsorption.
It is very effective in flocculating, decolouring, killing algae and removing organics It is use in latex waste clarification , oil-water seperation, iron congulation. The product enjoys small dosage but can cause big flocs, rapid precipitation and low turbidity residue, and it can also produce small amount of sludge. It is adaptable to wide range of pH value, between 0.5 and 1.4.
It can be widely used to treat source water and sewage water.

Water treatment coagulants are comprised of positively charged molecules that, when added to the water and mixed, accomplish this charge neutralisation. inorganic coagulants, organic coagulants or a combination of both are typically used to treat water for suspended solids removal.

In a colloidal suspension, particles will settle very slowly or not at all because the colloidal particles carry surface electrical charges that mutually repel each other. A coagulant (typically a metallic salt) with the opposite charge is added to the water to overcome the repulsive charge and “destabilise” the suspension.

PolyDADMAC is smelless, tasteless and harmless.
