The cylindrical side vessel has an over-flow outlet 8 so graywater can overflow and bypass the closed valve and flow directly to the sewer or onsite wastewater system in the event that the free outflow of graywater is restricted from either clogging of the mesh filter or other blockage, without restricting or limiting the continued normal free outflow of graywater from the building's plumbing fixtures.

Abstract: In a method of filtration, a liquid to be filtered is brought into contact with the surface of a filter medium and is passed through the filter medium. A supernatant liquid layer is created on the surface of the filter medium, and the upper level of the liquid layer is suitably controlled. A hydraulic path is organized in the liquid layer, and a stream of the liquid to be treated is brought to the inlet of the hydraulic path. Liquid that has passed through the filter medium is recovered for n cycles by reinjecting the liquid into the supernatant layer at the outlet of the hydraulic path, producing in a section of the path a meeting of two opposed streams. The treated liquid is then drawn off after n cycles.

Abstract: The invention relates to a method and apparatus for filtering a liquid. The filtering is conducted using one or several filter elements in the filter housing, the operation being based on the alternation of filtering stages and air flushing stages. According to the invention, upon transferring from the flushing stage to the filtering stage, the filter housing is filled with liquid so that the liquid pushes the flushing air in the housing from the upper end of the housing into a separate air container so that air is compressed to a higher pressure in the container. During the filtering stage, air remains in the container, and after the filtering stage, air compressed in the container is allowed to push liquid out of the filter housing with its pressure. Further, the connection between the air container and the filter housing can be arranged so that air compressed in the container participates in the backflushing of the filter elements.

Abstract: A liquid filter mainly intended for oil or fuel in internal combustion engines, in which the filter comprises a replaceable filter cartridge (17). The filter cartridge is housed in a housing having an essentially central symmetry comprising a housing base and a cover which is designed to be screwed on. In order to avoid leakage residual liquid when the filter housing is opened, especially if the liquid filter is mounted horizontally, a drain screw (22) is actuated before the housing is opened, and in order to achieve the highest possible degree of drainage, the drain screw is moved to the lowest possible position by rotating a threaded member (11) by at most 360°. Upon rotation of the threaded member, a sealing ring (13) ensures tightness in the base (10) of the housing in an area “a”. After all the liquid has drained out of the housing through the drain opening (23), the filter housing can then be opened to enable replacement of the filter cartridge without danger of leakage.
