PDADMAC - homopolymer DADMAC
PDADMAC is the abbreviation for polydiallyldimethylammonium chloride. This chemical compound is an organic polymer.
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.
