Abstract: A FOG waste treatment facility includes a slipstream loop incorporating circulation pumps, heat exchangers and anaerobic digesters for continuously circulating actively digesting sludge at a rate to preclude solid settlement accumulation warmed actively digesting sludge is pumped from the slipstream loop through a rock trap into a delivery/input loop both for aiding delivery of FOG waste to, and for partially filing, a receiving/conditioning holding tank. The actively digesting sludge softens and liquefies the FOG wastes offloaded into the holding tank for further treatment at a desired treatment temperature range. The contents of the receiving/conditioning holding tank are continuously mixed by a bottom-top recirculation chopper pump to pre-treat the FOG wastes, and decreasing solids particle size. The produced, flowable feedstock slurry can then be injected back into the actively digesting sludge slipstream loop at a controlled rate.

Abstract: A system and method integrating treatment of waste, polar Fats/Oils/Greases (FOG) with conventional anaerobic wastewater treatment facilities for biologically fueling digestion of solids in, and steady state production of methane from treated wastewater streams that includes a slipstream loop circulating warmed, actively digesting sludge from the base to the head of the anaerobic wastewater treatment facility, a conditioning tank with input screened by a rock trap, actively digesting sludge pumped from the slipstream loop into the tank via the rock trap, before and after FOG wastes are pumped from a hauler tank via a hose connecting to the rock trap into the conditioning tank and mixed with actively digesting sludge in the tank to produce a feedstock slurry rich in volatile fatty acids for injection at a metered rate back into the actively digesting sludge slipstream loop for introduction at the head of the anaerobic wastewater treatment facility.

Abstract: Integrated sewage or digestible wastes, and fats, oils, greases and waxes (FOG) waste treatment methods, systems and facilities include a slipstream loop incorporating circulation pumps, hot water heat exchangers and conventional anaerobic digesters for continuously circulating actively digesting sludge at a rate to preclude solid settlement accumulation as a warm flowable slurry source. The warmed actively digesting sludge is pumped from the slipstream loop through a rock trap into a delivery/input loop both for aiding transport or delivery of FOG waste to, and for partially filing a closed receiving/conditioning holding tank, where the warmed actively digesting sludge softens and liquefies the FOG wastes offloaded into the holding tank for further treatment at a desired treatment temperature range (whether psychrophilic, mesophilic, or thermophilic).
