ABSTRACT:
A method for solubilizing particulate or colloidal materials in wastewater treatment comprising the steps of cultivating aerobic bacteria in the presence of oxygen in an activator solution containing a food source until the level of the food source drops below 50 mg/l of soluble chemical oxygen demand (sCOD) and said bacteria begin producing increased amounts of enzymes which solubilize particulate or colloidal materials thereby producing activated bacteria and thereafter contacting said activated bacteria or enzymes with said particulate or colloidal materials under conditions which solubilize said particulate or colloidal materials. The method is particularly useful for solubilizing particulate and/or colloidal materials containing insoluble starch, grease, fat and protein with enzymes such as amylase, lipase and/or protease.
