The present invention is directed to a debris catching and removing apparatus and method. For example, bar screens or grids for collecting and removing trash or debris from storm, waste water, or sewage systems, and mounting systems and methods therefore are provided. These apparatus and method may provide a long-lasting, light-weight, and low-cost debris screen screening solutions for removing trash or debris from, for example, storm, waste water, or sewage systems. The invention may be particularly applicable to small lift stations that use submersible pumps or surface mounted pumps that suction waste water from a wet well.

A water circulation system for a pool comprises a water outlet assembly mounted to an inner wall of a pool, and in fluid communication with an external pump through a water outlet pipe. The water circulation system also includes an air inlet assembly mounted to the pool a preset distance from the water outlet assembly, and an air outlet assembly attached to the water outlet assembly and in fluid communication with the water outlet assembly. An air inlet passage connects the air inlet assembly to the air outlet assembly, so external air can enter the air inlet assembly and be introduced to the water outlet assembly through the air outlet assembly. Air is introduced to the water outlet by the air outlet when the water outlet assembly is blocked, reducing negative pressure at the water outlet and reducing risk that a portion of a user's body is drawn against or into the water outlet.

A filter device has at least one filter element (37) accommodated in a filter housing fluid-connected to a fluid tank (1). The filter housing has at least one connection fitting (29) forming a fluid connection to the filter element (37). The filter housing is formed by a filter bowl (13) molded into the tank (1). The bowl bottom (17) has the connection fitting (29) associated with the element receiver.

An internal oil filter is installed at least partially inside a crankcase and/or an oil sump of a compressor. The internal oil filter can receive oil from an oil pressure regulator and filter the oil via filter media. The received oil radially penetrates through the filter media and flow directly into the oil sump from an outside surface of the filter media. This can eliminate the need of fluid lines connecting an outlet of an oil filter to the oil sump and any sealing mechanism therebetween.

A device for the suction filtration of fluids, such as urea solutions for exhaust gas after-treatment systems, has a tank (2) storing the fluid, and a filter element (34) arranged in the tank and provided with a filter medium (32) separating the tank contents from a clean-side inner filter cavity (20). The filter cavity extends from the bottom (10) of the tank (2) to a filling level height (28) and corresponds to a part of the filling volume of the tank (2). On the filter cavity (20), a suction connection (22) discharges the cleaned fluid by a suction pressure corresponding to a system operating pressure. The filter element (34) is provided with a filter medium (32), which is air-impermeable if suction pressures are within the range of a low system operating pressure.

A measurement portion and an antenna are allowed to be provided in a filter device by simply mounting one member. An antenna unit that includes an antenna configured to communicate with an IC tag is provided in a vicinity of a first end face as one end of a case. A sensor is provided inside the case and a back side of the case with respect to the antenna unit.
