Abstract:
A system for treatment of waste from a plurality of waste-generating sites, said waste containing water and contaminants, said contaminants including flow-impediment contaminants, said system comprising:a plurality of pretreatment units, a collection line, a plurality of gathering stations and a final treatment facility; each of said plurality of pretreatment units capable of receiving waste from at least one of said waste-generating sites; each said pretreatment unit comprising pretreatment means for removing said flow-impediment contaminants from said waste; said collection line providing fluid communication of said pretreated waste from each said pretreatment unit to one of said plurality of gathering stations; each of said plurality of gathering stations located remote from each of said plurality of pretreatment units; said collection line further providing fluid communication of said waste from said plurality of gathering stations to said final treatment facility; said plurality of gathering stations each comprising a pump chamber and a pump; said collection line comprising a plurality of line segments; each said pump chamber operationally connected to at least one of said plurality of line segments to receive said waste; each said pump operationally connected to one said pump chamber and at least one said plurality of line segments to transmit said waste toward said final treatment facility; said final treatment facility remote from each of said plurality of gathering stations; said final treatment facility comprising final treatment means for treating remaining contaminants contained in said waste; each said pump selectively operable to communicate said waste from one of said plurality of gathering stations through one of said plurality of line segments; a sensing system and a feedback system operationally connected to selected measurement locations of said system; said sensing system capable of identifying data concerning the waste at a selected measurement location; said feedback system capable of processing said data to determine a quantity of waste to be pumped from a gathering station; and said sensing system and said feedback system operable to selectively retain waste at selected gathering stations and to selectively pump waste from other selected gathering stations.
