Uses of cationic polyacrylamide:
(1) cationic polyacrylamide can be used for sludge dehydration according to the nature of the sludge, which can be effectively dehydrated before the sludge enters the filter press. During dehydration, large flocs are produced that do not adhere to the press cloth and do not disperse during the press filtration process. Thick mud cake, high dehydration efficiency, mud cake moisture content below 80%.
(2) For the treatment of domestic sewage and organic wastewater. This product in compatible or alkaline medium positive electric, sewage suspended particles with negative charge flocculation precipitation effect, make it clear. Such as food and alcohol production wastewater, paper waste water, urban sewage treatment plant wastewater, beer wastewater, monosodium glutamate plant wastewater, sugar wastewater, high organic content of wastewater, feed wastewater, textile printing and dyeing wastewater. The effect of cationic polyacrylamide is several times or dozens of times higher than anionic, non-ionic polyacrylamide or inorganic salts, because such wastewater is generally negatively charged.
(3) cationic polyacrylamide used as flocculant, used to treat tap water with river water as the source of water. It has the advantages of small dosage, good effect and low cost, especially when used with inorganic flocculant. It will become a flocculant for water plants in the Yangtze River and Yellow River basins.
(4) reinforcers and other additives for paper making.
