Apparatuses and methods for improved operation of a fluid purification system. The apparatuses and methods may include an evaporator chamber and a filter chamber and include directing compressed air into the air inlet of an evaporator chamber, drying the compressed air before directing the compressed air into the air inlet of the evaporator chamber, reducing pressure at the air outlet of the evaporator chamber to less than atmospheric pressure, collecting material exiting the evaporator chamber through the air outlet in a particulate bottle, and drawing air from the particulate bottle into the air inlet of the evaporator chamber.

A filter element comprising a filter media having a first end and a first endcap coupled to the first end of the filter media. The first end-cap includes a flexible first endcap body having a first endcap rigid reinforcing member internally embedded therein. The first endcap rigid reinforcing member may comprise a wire mesh screen and the filter media may comprise a pleated filter media. The filter element may further comprise a second end-cap coupled to a second end of the filter media. The second endcap may include a flexible second endcap body having a second endcap rigid reinforcing member internally embedded therein.

A filter cartridge includes a threaded sleeve having a seal holder recess and seal member. The filter cartridge is for removably threading onto a filter head that includes threads for connection to the filter cartridge by way of the threaded sleeve. The filter head includes a ramp that engages the seal member to form a seal. The force needed to make the seal is a torque of less than 10 N-m.

Fibrous porous filter elements formed by joining two fibrous porous sections, porous filters comprising the joined sections, filter baskets and filter devices comprising the elements and filters, methods of making the filter elements and filters, and methods of filtration using the filter elements and filters, are disclosed.

The present development is a septic tank or wastewater treatment tank outlet filter cleaning device. More specifically, the device is an outlet filter cleaner for a slotted filter used to reduce solid waste transfer into a septic tank effluent. The device comprises a central shaft with at least one cleaning disc, wherein the cleaning disc comprises a body which is mounted on the shaft and wherein a plurality of fingers protrude from the body, preferably in locations substantially identical to the positions of the openings in the wall of the tube.

In one aspect, a modular filter assembly for filtering fluid that flows in a flow direction therethrough is disclosed. The assembly includes a first housing section having a first filter element; a second housing section having a second filter element; and a connector disposed between the first and second housing sections. A housing includes the first housing section, the connector, and the second housing section. The flow direction is through the first and second filter elements in series.

A cleaning system for a vehicle oil circuit is provided, including a heat exchange unit. The heat exchange unit includes an oil inlet channel, a first container, a second container and an oil outlet channel. The first container is located within the second container. The first container defines a first space communicated with the oil inlet channel and the oil outlet channel, and the first container and the second container define a second space therebetween and non-communicated with the first space. The oil inlet channel guides an oil from the vehicle oil circuit to the first space, and the oil outlet channel discharges the oil from the first space. The first space receives the oil, and the second space receives a detergent. When the oil is in the first space, a heat of the oil is transferred to the detergent through the first container.
