Polyacrylamide for Electroplating Plant Wastewater Treatment
Case name: electroplating wastewater treatmentSewage problem: electroplating wastewater mainly contains heavy metal ions that cannot be degraded by nature, and the pollution of the environment is quite serious
Solution: Use polyacrylamide for treatment of electroplating plant
Treatment results: to meet the discharge
Electroplating wastewater with polyacrylamide features include flocculation, PAM can make the suspended material through the electric neutralization, bridging adsorption, flocculation. Adhesion, through mechanical, physical and chemical effects, it can play the role of adhesion. Reducing resistance, PAM can effectively reduce the friction resistance of the fluid, adding trace PAM in water can reduce the cationic 50-80%. Increase the tone, PAM in the neutral and acid conditions have the effect of increasing the phase, when the PH value of more than 10 PAM is easy to hydrolyze the semi-network structure, thickening will be more obvious. Polyacrylamide flocculation precipitation is the occurrence of a chemical reaction that generates a substance that is insoluble in the solution in which the reactant is located. From the literal meaning of the word is to precipitate under the action of gravity to remove. Suspended material in the sewage, which is a physical process, easy to implement, good results, is one of the important technology of sewage treatment.
