ABSTRACT:
A system and related method for the treatment of dairy and other food processing plant wastewaters provides recoverable by-products from two separate stages and a final water effluent clean enough for direct discharge or process reuse. The system provides an effective alternate to conventional wastewater treatment and includes, as its operating steps which provide useful by-products, dissolved air flotation and membrane separation. The recoverable by-products from these two unit operations are high in amino acids and provide sufficient nutritional value to permit their use as animal feed or fertilizer products.
