专利汇可以提供Treatment of fermentation waste liquid专利检索，专利查询，专利分析的服务。并且PURPOSE: To economically perform treatment of the title waste liquid with capableness of decoloration by filtering fermentation waste liquid obtained after utilizing waste molasses with a membrane such as a reverse osmosis membrane or an ultrafiltration membrane treated by charging.
CONSTITUTION: In a method that waste molasses in used for culture or fermentation, etc., and is subjected to membrane filtration, firstly waste liquid is pretreated by precision filtration and centrifugal filtration, etc., in accordance with necessity. Then it is subjected to membrane filtration with a charged above membrane in which electric chargeable synthetic high molecules incorporating insoluble polyamine and sulfonic acid group such as polyaminosulphone is stuck and filled to a skin layer. By such a way, waste liquid can be concentrated to 10 times or more and decoloration not less than 70% is enabled and this treatment is utilizable for fermentation industry such as bread yeast industry and alcohol industry.
