Abstract

PURPOSE: To utilize the waste liquid containing proteins, fats, hydrocarbons, etc. as valuable resource, and to reduce the BOD and COD of the liquid within or below the permissible level for discharge, by concentrating the liquid with a separating membrane, and fermenting the permeated liquid with yeast.
CONSTITUTION: Liquid containing proteins, fats, hydrocarbons, etc. e.g. waste liquid obtained by recovering starch from potato, etc., or waste liquid of soybean processing, etc. is treated with a separation membrane such as a reverse osmosis membrane, ultrafiltration membrane, micro-filtration membrane, etc. The permeated liquid is sterilized preferably by heating under pressure, fermented with a yeast selected according to the kind of the content of the permeated liquid, and separated into the fermentation product and the liquid component.
