Waste Activated Sludge Anaerobic Contact Waste Stream Treatment Process-Recycle
US Patent:
2006002, Feb 9, 2006
Filed:
Aug 5, 2004
Appl. No.:
10/913822
Inventors:
Stephen Hough - Santa Ana CA, US
Balakrishnan Narayanan - Concord CA, US
Balakrishnan Narayanan - Concord CA, US
International Classification:
C02F 3/30
US Classification:
210605000, 210624000, 210195300
Abstract:
The waste activated sludge anaerobic contact waste stream treatment recycle method and system for treating a waste stream may have an influent waste stream communicated to an anaerobic contact element. A waste activated sludge produced from a second influent waste stream process may be introduced into the anaerobic contact element and mixed with the influent waste stream for processing therein. The anaerobic contact element may be maintained for conditions to facilitate the uptake of soluble organic pollutants and to form a fluid having a particulate matter contained therein. The resulting fluid may have the particulate matter separated from the fluid to produce a treated effluent and a waste sludge. The waste sludge may be further separated to retain a first portion as a recycled sludge to the anaerobic contact element and to output a second portion as an effluent waste sludge.
