Application of stripping agent:
1: Decoloring agent is used in sludge dewatering.According to sludge characteristics,the corresponding model of stripping agent will be applied, for the purpose of effective sludge dewateringbefore pressure filtration.Larger floc formed in dewatering shall not be stuck with filter cloth, and not dispersed in pressure filtration. Filter cake is thick, dewatering efficiency is high, and cake moisture content is about 80% or less.
2: Decoloring agent is used in the treatment of domestic sewage and organic waste water.Stripping agent showing the electropositivityin acidic or alkaline media plays a role in flocculation and clarification of waste waterwithsuspended particles carrying negative charge.For example, in a variety of waste watertreatment, cationic polyacrylamide is effectivelyseveral or tens times anionic, nonionic polyacrylamide or inorganic salt, because such waste water generally carries negative charge.
3: In the event of flocculation aid in tap water originated from river water, it features less dosage, better effect and lower cost, especially ideal for the combination of inorganic flocculant.
4: In paper making, Decoloring agent, as enhancer or another additive,is used to enhance retention rate of filling material and pigment and paper strength.
5: As oil field aid, such as clay expansion prevention aid, acidification thickening agent.
