摘要: The present invention provides a method for removing secondary fiber contaminants from paper mill process waters comprising adding polyvinyl chloride, cationic polymeric coagulant and flocculant to containing in an amount sufficient agglomerate the larger particles sizes, water by dissolved air flotation clarification technique. addition of particulate chloride combination with prior DAF causes become preferentially coated particles. This coating is what subsequent removal be more effective.
