Foshan polyacrylamide polyacrylamide rich students Certified

Anionic polyacrylamide industrial wastewater treatment for suspended particles, representing a high concentration of particles with a positive charge, water PH value is neutral or alkaline water, iron and steel plant wastewater, waste paper production, beer production wastewater, metallurgy plant waste water, coal washing waste water sewage treatment works best. Drinking water treatment applied to water from rivers, sediment and mineral content, more muddy. Textile auxiliaries used in the textile, carpet industry sizing, quick-setting cement, synthetic resin coatings. Photosensitive polymer, a binder, a dispersant. Paper additives used for clarification of liquid caustic soda, fiber dispersing agent, can improve the freeness, filler retention agents, paper strengthening agent, it can be used to improve the filtration rate and white water recovery. Starch factory and the loss of starch ethanol plant alcohol recovery starch factory wastewater containing starch lot, allow starch particle coagulation and sedimentation, and then the precipitate was filtered through a filter press into a pie machine, can be used for feed. Alcohol alcohol plant can also be used polyacrylamide dehydration, pressure filtration for recycling. Dyeing with polyacrylamide use: dosage concentration polyacrylamide more dilute solution, the better, the more dilute the concentration of dosing solution enables the rapid expansion in the water, thoroughly mixed, to prevent excessive concentration of colloids protection phenomena affect and effect. But the concentration is too thin can cause huge dosing device. General dosing concentration in thousandths of concentration appropriate. Currently, the leather dyeing wastewater treatment or physicochemical method based, but not ideal. Although dyeing wastewater treatment methods Some methods for leather dyeing wastewater, but compared with the biological chemical method were running high cost, therefore, from a business point of view, research and development of a compact, fast processing speed and stable operation of new high anaerobic reactor, is the most cost-effective leather dyeing wastewater treatment. l, when used, dubbed 0.1 a 0.2% aqueous solution concentration to use neutral salts debris-free water is appropriate. 1, when used, dubbed 0.1 a 0.2% aqueous solution concentration to use neutral salts debris-free water is appropriate. 2, when dissolved, the cationic polyacrylamide products even thrown into stirred water, stir speed control in 100,300rPm. Appropriate heating ((60 ℃), can accelerate the dissolution. 3. Adjust liquid to be treated PII value, so that the product fully functional (the amount of PII by selecting the best value and the test of this series.) 4, adding a cationic When polyacrylamide product solution, should speed mixed with liquid to be treated, there floc, the stirring speed to slow down in order to facilitate and accelerate the growth of floc settlement.
