ABSTRACT:
A process and system for waste water treatment including a concentration means positioned at the front of the treatment system in order to concentrate the starches and sugars contained in a waste stream. In a mixing vessel, the concentrate stream is treated with a variety of additives in order to increase consumption of the biological components and to produce a stream having a predictable and predetermined level of soluble starches. The waste stream is solubilized by subjecting the stream to heat and enzyme treatment such that the starches and complex sugars are converted to simple sugars. In a fermentation vessel, a carefully selected yeast strain is introduced into the waste stream and permitted to feed on the sugars. The operating conditions in the vessel (e.g. pH, temperature, oxygen supply, and mineral supply) are carefully controlled to enhance consumption of the biological components in the waste stream. The final product is a marketable grade yeast and a clean water stream for environmentally safe disposal.
