Abstract
A process and system for pretreating, gathering, transmitting and finally treating waste produced at multiple locations includes pretreating the waste proximate the generation site, gathering the pretreated waste and transmitting the waste to a final treatment facility. One or more gathering stations, with sensing and feedback mechanisms, allow for controlled injection of waste to collection lines, and segments thereof, to control system demand through the collection line and to final treatment facility. The pretreating step includes removing particulates that impede the flow of waste through the collection lines.
Claims9
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.
