A mobile sewage treatment and water reclamation system for rapid deployment to augment existing wastewater systems and provide interim service in lieu of permanent facilities, includes: (a) denaturing stage wherein raw sewage is first ground into suspendable grit, its pH first lowered to kill acid-sensitive bio-organisms, then raised to kill base-sensitive bio-organisms, and then neutralized; (b) clarifying stage employing an inverted-cone tank to circulate the solution after injection with chemicals to flocculate small particles for collection in a layer for siphoning off; and (c) disposal stage wherein clarified water passes through media filters to remove remaining solids and odors, the effluent water being clean enough for irrigation, aquatic life and discharge into waterways; and wherein sterile sludge is pressed into semi-dry solids, then dried, crushed, powdered and bagged for use as high-nitrate biomass fertilizer or for fossil-fuel power co-generation applications. |
