ABSTRACT:
A method and apparatus for wastewater treatment to minimize solid-waste by-products requiring disposal in a landfill site. The system for carrying out the process utilizes initial screening and dissolved air flotation processes to remove a large portion of the solid-waste matter within the wastewater. The wastewater is then processed by anaerobic and aerobic means to clarify the wastewater to a point where it may be discharged into normal sanitary sewage systems. The solid-waste matter removed during the process is dewatered and composted. The composted matter may be used for land applications such as fertilizing or fill dirt.
