Abstract
A water treatment system filters out solid material containing carbon, and provides that solid material to a fermenter. Volatile fatty acids are produced within the fermenter. After fermentation, a second filtering operation is utilized to permit passage of water and volatile fatty acids while filtering out solids from the fermenter. The volatile fatty acids are used as a food source for bacteria during secondary treatment of the water.
