Abstract
A wastewater treatment system comprises a septic tank which flows liquid effluent through an aerobic filter. The aerobic filter has a textile filter media. In one aspect, the textile filter media has relatively high open area and relatively low or moderate water holding capacity. In another aspect, the filter media comprises a plurality of vertically oriented textile sheets having a relatively small gap between adjacent sheets.
Claims30
A treatment assembly for treating sewage wastewater, comprising:
- (a) a tank having a tank outlet;
- (b) an aerobic filter having a filter media, a filter inlet connected to said tank outlet, and a filtrate outlet;
- and
- (c) said filter media comprising a textile having an open area of at least 88%.
A treatment assembly for treating sewage wastewater, comprising:
- (a) a tank having a tank outlet;
- (b) an aerobic filter having a filter media, a filter inlet connected to said tank outlet, and a filtrate outlet;
- and
- (c) said filter media comprising a textile having a water holding capacity of less than 70%.
A treatment assembly for treating sewage wastewater, comprising:
- (a) a tank having a tank outlet;
- (b) an aerobic filter for treating tank effluent having a filter medium comprised of a plurality of vertically oriented textile sheets, a filter inlet connected to said tank outlet, a spray mechanism connected to said filter inlet and located proximate a top of said filter medium, and a filtrate outlet;
- and
- (c) said filter medium having at least a first sheet and a second sheet horizontally spaced apart from one another and defining a gap therebetween, said first sheet and said second sheet being horizontally spaced sufficiently close together so that substantially all of said tank effluent sprayed from said spray mechanism into said gap passes through at least one of said first sheet and said second sheet.
A method for treating sewage waste water, comprising:
- (a) providing a tank having a tank outlet;
- (b) providing an aerobic filter for treating tank effluent;
- (c) connecting a filter inlet for said aerobic filter to said tank outlet, and connecting a spray mechanism to said filter inlet, and providing in said aerobic filter a filtrate outlet;
- (d) providing a plurality of vertically oriented textile sheets;
- (e) horizontally spacing each of said plurality of vertically oriented textile sheets apart from each other so as to define a respective gap between each respective pair of adjacent textile sheets, each said respective gap having a width such that substantially all of said tank effluent sprayed from said spray mechanism passes through said textile sheets.
