Polydadmac
Polydiallyl ammonium chloride is a colorless to pale yellow transparent liquid. It is a water-soluble high-molecular-weight polyelectrolyte that can completely dissolve in water to form a true solution. Because the polymer contains strong cationic groups and active adsorption groups, it can destabilize, coagulate, and disperse suspended particles and water-soluble substances containing negatively charged groups through charge neutralization and bridging adsorption. It has a wide pH range (0.5~14) and is non-toxic, tasteless, and odorless.
These are liquid cationic polymers of varying molecular weights, which can be efficiently used as primary coagulants and charge neutralizers in liquid-solid separation processes across various industries.
This product can be used as a primary coagulant for the purification of drinking water and the clarification treatment of various industrial wastewaters. It conforms to NSF60 standards and is suitable for drinking water treatment processes, with a maximum concentration of 25 ml/L for coagulation and flocculation.
This product can be used as a flocculant, decolorizing agent, and dehydrating agent in drinking water, raw water, and wastewater treatment; as a bactericide, softener, antistatic agent, conditioning agent, and fixing agent in the textile printing and dyeing industry. Furthermore, it can be used as a surfactant in the chemical industry.

Usage and Precautions:
1) It can be diluted in any proportion and added uniformly and continuously to the wastewater treatment system, or diluted 5 to 20 times and added directly to the wastewater, followed by stirring and sedimentation.
2) When treating water and wastewater from different sources, the dosage needs to be determined based on the turbidity and concentration of the water being treated. The optimal dosage can be determined through small-scale trials.
3) The dosing point and stirring speed must be carefully selected to ensure uniform mixing with the materials and to avoid crushing the flocs.
