ABSTRACT:
Disclosed is a system for reducing the demand of wastewater volume flowing through a wastewater collection piping system and thereby increasing the effective capacity of the system. A portion of the wastewater is diverted from a sewer main. The solids are separated from the liquid, for example, by a vortex separator. The recovered liquid can be treated and made available for local reuse. The concentrated solids are reintroduced into the main sewage line in a portion that adjusts the wastewater loading in the sewer main to a predetermined amount or predetermined range. Also disclosed is a system capable of reintroducing the concentrated solids into the sewer main in a portion that adjusts the solids loading in the sewer main to a predetermined amount or predetermined range.
