  • Wastewater pretreatment, gathering and final treatment process
    Patent number: 6669839
    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.
