    摘要： An improved method and apparatus for treating wastewater in a recirculating filter is disclosed. Solids are removed from the wastewater by gravitational separation and the wastewater is flowed to a tank. At least a portion of the wastewater is flowed from the tank to a filter comprised of filter media and flowed through the media to produce a filtrate. The amount of wastewater in the tank is sensed. When the amount of wastewater sensed is at least a predetermined amount, a fraction, less than all but more than none, of the filtrate is returned to the tank. When the amount of wastewater is less than the predetermined amount, more than the fraction of filtrate is returned to the tank by decreasing resistance to flow of the filtrate to the tank. The apparatus includes a tank and a filter interconnected by a conduit for conducting liquid from the tank to the filter. A conduit assembly interconnects a filter outlet and a discharge conduit for conducting liquid from the filter to the discharge conduit. The conduit assembly includes a shunt conduit connected to the tank for shunting at least some liquid from the filter to the tank bypassing the discharge conduit by selectively varying resistance to flow of liquid in the shunt conduit.

    摘要： A method of improving the quality of septic tank effluent is disclosed. Sewage wastewater having a significant concentration of waste solids is flowed to a septic tank. In the septic tank the solids are allowed to separate from the wastewater to form a relatively clear horizontal liquid layer between sludge and scum layers. At least a portion of the liquid layer is flowed from a recirculation outlet through an aerobic filter to produce a filter effluent. The filter effluent is flowed to the septic tank. A septic tank effluent is discharged from a septic tank discharge outlet which is spaced apart from the inlet and which is in fluid communication with the liquid. The septic tank effluent has reduced levels of total nitrogen, BOD and total suspended solids.

    摘要： An on-site wastewater treatment system distributes septic tank effluent over a particulate media filter bed through a distribution manifold at a sufficient volumetric flow rate relative to the cross-sectional area of the distribution conduits to inhibit undesirable biological growth in the conduits and in the filter by creating a scouring effect in the conduits. This effect prevents clogging of the conduits and maximizes the even distribution of effluent in the filter. A mesh fabric intercepts the downward flow of the effluent in the filter to further aid in the even distribution of effluent in the filter. Orifice shields also aid in such distribution by preventing clogging of orifices embedded in the filter media. A high pressure switch in the distribution manifold and a high water alarm in the filter pump basin indicate when required maintenance is necessary, and the switch controlling the high water alarm temporarily disables the septic tank pump as well. A flush system is provided to easily remove any clogging solid material from the distribution manifold.

    摘要： A method of filtering solids from the effluent from a wastewater collection container such as a septic tank is disclosed. A mesh screen filter is immersed in wastewater having a concentration of waste solids which have been allowed to distribute into a scum layer and a sludge layer with a horizontal layer of liquid therebetween. The filter is surrounded with a housing, and the interior surface of the housing is exposed to the horizontal layer of liquid through a plurality of apertures in the housing. Liquid from the horizontal layer flows through the apertures into the housing and thereafter the liquid flows from one side of the filter to an opposite side thereof through a mesh screen filtering surface area greater than the interior surface area of the housing. Thereafter, the liquid flows through a liquid effluent outlet of the container. This filter is very efficient and consequently provides a high quality effluent, while resisting clogging and resultant collapse of the mesh screen surface area.

    摘要： Treating wastewater by receiving wastewater having a reduced concentration of waste solids into a secondary containment space and allowing the waste solids to distribute into a lower horizontal sludge layer, an upper horizontal scum layer, and a relatively clear horizontal layer of liquid therebetween; flowing the liquid from the relatively clear layer through at least one filter element enclosed in a housing the top of which is submerged below the wastewater level of the secondary containment space; and thereafter flowing the filtered effluent out of the housing. In some embodiments, the filtered effluent may be discharged from the secondary containment space using an effluent pump configured with a conventional flow inducer or, alternatively, using an effluent pump sealably configured with a shortened flow inducer thereby allowing discharge of the filtered effluent to a wastewater level below that of the pump's intake.
