Patent abstract
A method for removing inert solids from low-yield wastewater treatment processes. The method includes combining wastewater with bacteria-laden sludge in a mainstream reactor to form a mixed liquor, separating the mixed liquor into a clear effluent and activated sludge, returning a first portion of activated sludge to the mainstream reactor, treating a second portion of activated sludge in a sidestream bioreactor prior to returning the second portion of activated sludge to the mainstream reactor, and employing a screening device within the wastewater treatment process to remove inert solids.
