Abstract: A wastewater treatment system uses a primary treatment vessel and a secondary vessel with a filtration unit therebetween. Continuous backwashing of the filtration unit occurs when a well pump is activated to empty the secondary vessel. A portion of fluid discharged by the well pump backwashes the filter continuously as the secondary treatment vessel is emptied.

Abstract: A wastewater treatment system for domestic sewage uses a primary treatment vessel and a secondary vessel with a filtration unit therebetween. Continuous backwashing of the filtration unit occurs when a well pump is activated to empty the secondary vessel. A controlled portion of fluid discharged by the well pump backwashes the filter continuously as the secondary treatment vessel is emptied.

Abstract: An apparatus for the treatment of wastewater from relatively small structures such as single family residences, dwellings and the like includes first and second vessels connected by a flow line, the first vessel including a wastewater inlet and the second vessel including an outlet for the discharge of clarified water. A transverse baffle divides the second vessel into aeration and clarifier sections, the clarifier section including a transversely mounted inclined plate which prevents the accumulation of solid material in the clarified section and redirects the solid material back into the aeration section. A multiple angle discharge piping arrangement prevents clarified liquid from discharging the apparatus until it has made at least two right angle turns before reaching the discharge piping of the unit.
