A wastewater treatment system includes inner and outer relatively telescopic units, the outer telescopic unit including an outer container having a bottom wall and a peripheral wall collectively defining a generally upwardly opening chamber, a filter exteriorly of the peripheral wall and defining therewith a first downstream settling zone, control openings in the peripheral wall for controlling wastewater flow through the first settling zone generally in response to the level of wastewater in the first settling zone, the inner telescopic unit including an inner container having a chamber defined in part by a peripheral wall, the peripheral walls being in relatively spaced relationship to each other and therebetween defining a second settling zone, a third settling zone within the inner telescopic unit chamber, and the inner and outer telescopic units each being a distinct unitized structure which permits the same to be bodily telescopically assembled and disassembled.
A wastewater treatment outer unit telescopically assembled relative to a wastewater treatment inner unit to define therewith a wastewater treatment mechanism comprising an outer container, said outer container including a bottom wall and a peripheral wall collectively defining a generally upwardly opening chamber having an upper peripheral edge, filter means exteriorly of and spaced from said peripheral wall and defining therebetween a settling zone, control means in said peripheral wall for controlling wastewater flow through said settling zone generally in response to the level of wastewater in said settling zone, means for unitizing said filter means and said outer container, and means for supporting said wastewater treatment inner unit in said outer unit in axially spaced relationship to said bottom wall.
A wastewater treatment inner unit telescopically assembled relative to a wastewater treatment outer unit to define therewith a wastewater treatment mechanism comprising an inner container, said inner container including a top wall and a peripheral wall collectively defining a generally downwardly opening chamber having a lower peripheral edge, a plurality of stacked baffle plates within said chamber defining a settling zone, means for unitizing said baffle plates and said top and peripheral walls wherein said inner unit can be bodily telescopically assembled and disassembled relative to said outer unit, means for supporting said inner unit within and in axially spaced relationship to said wastewater treatment outer unit, means for discharging wastewater from said chamber through said top wall, and means defined by said top wall for directing discharged wastewater in a generally radially outward direction.
