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.
