A filter cartridge (5) with a housing enclosing a filter volume filled to about 80% with a filter granulate (15) is screwed into a joint (7) of a connecting piece (1) by means of a port (12) ending in an outflow opening (13) and being connected to an outlet line formed by a second fitting (3), and surrounded with a distance by a casing (4) that is screwed to the connecting piece (1). An inlet line formed by a first fitting (2) opens into an intermediate volume (6) lying between the casing (4) and the outer side of the filter cartridge (5) in such a way that untreated water enters into the outlet line via the intermediate volume (6) and through the bottom (9) which is perforated by slots (10), the filter granulate (15), the intermediate floor (11) that is likewise slotted and the port (12). In order to reduce the flow resistance, the port (12) is provided with bypass openings (14) to allow untreated water to pass also directly out of the intermediate volume (6) into the port (12).

Systems, devices, and methods for providing nutrient removals in an up flow filtration storm water system for treating water to very high clean levels using filtration media. A filtration media can be supported by a screen above a floor in a vault allows for incoming storm water to pass into a void space above the floor into the screen and filtration media and then out an outlet to the vault. The filtration media can include recyclable and/or natural particles. Layers of river rocks can be placed on top of and below the filtration media. The captured debris can drop to the floor. The long lasting filtration media can be cleaned by being backwashed.

An interface seal assembly for sealing a tubular filter element relative to a first component and a second component of a fluid filtration system. The interface seal assembly comprises an body located between the first and second components, and having: an aperture extending through the body for communicating with an internal cavity of the filter element; a first mounting surface comprising a first seal groove; and a second mounting surface opposite the first mounting surface, comprising a second seal groove. One of the first and second seal grooves has a circular shape, and the other has a non-circular shape. A first seal is located in the first seal groove, for sealing the interface body relative to one of the first and second components. A second seal is located in the second seal groove, for sealing the body relative to the other of the first and second components.

The present disclosure a mechanical filter element (2) for forming a static filter pack (11) to perform mechanical filtration of a liquid. The mechanical filter element (1) has one or more filter cell (19). The present disclosure also relates to a mechanical filter apparatus (1) having a filter chamber (10) containing a plurality of mechanical filter elements (2) for forming the static filter pack (11) to perform mechanical filtration of a liquid. The mechanical filter apparatus (1) is configured to generate a flow of the liquid through the mechanical filter elements (2) during filtration to form the static filter pack (11). Furthermore, the present disclosure relates to a method of mechanically filtering a liquid. A plurality of mechanical filter elements (2) each comprising one or more filter cell (19) are disposed in a filter chamber (10). During filtration, the liquid flows through the filter chamber (10) to establish a static filter pack (11) of said mechanical filter elements (2) to mechanically filter the liquid.

A filter medium layer includes filter media configured to capture suspended solids contained in a liquid to be treated and filtering aids configured to allow the suspended solids contained in the liquid to be treated to pass through the filtering aids. The filter media and the filtering aids are mixed together and the liquid to be treated is filtered by being passed through the filter media and the filtering aids as mixed together. A filter device includes the filter medium layer and a filter tank configured to accommodate the filter medium layer.

The present technology relates to control systems for use with fluid treatment systems. In one embodiment, for example, a fluid treatment system includes a vessel configured to receive a fluid having one or more constituents and to separate one or more constituents from the fluid. The system can also include a tube extending along at least a portion of the vessel and a sensor. The tube can be in fluid communication with a pressurized air source, and the sensor can be configured to obtain a measurement of an operating parameter. The system can also include a controller in communication with the sensor and pressurized air source. The controller can execute one or more algorithms to determine a filter parameter based on the measurement of the operating parameter, compare the filter parameter to a threshold, and, based on the comparison, activate or deactivate the pressurized air source.
