Systems and methods for treating a stream comprising hydrocarbons and an aqueous-based liquid are provided. The systems and methods may utilize a media composite comprising a mixture of a cellulose-based material and a polymer. In certain systems and methods, the media composite is capable of being backwashed. The stream comprising the hydrocarbons and aqueous-based liquid may be separated by contacting the stream with the media composite. In certain system and methods, the stream comprising the hydrocarbons and aqueous-based liquid may be coalesced by contacting the stream with the media composite.

The filter medium is a filter medium which uses a liquid containing oil and water as a separation target, and has a channel for the liquid. The filter medium includes a base constituting the channel, and one or more of nitrogen-containing fluorine compounds which are provided on at least a portion of a surface of the channel. The nitrogen-containing fluorine compound includes an oil-repellency imparting group and any one hydrophilicity imparting group selected from a group consisting of an anion type, a cation type, and an amphoteric type, in a molecule.

A filtration system and method is disclosed. The filtration system includes a separation system with a primary process vessel with a main body enclosing an internal volume, and a removable end cap coupled to one of the ends of the main body. The primary process vessel includes fluid apertures enabling a fluid stream to enter or exit the inner volume. The separation system includes a filter support positioned in the inner volume, and a filter assembly coupled to the filter support. In some embodiments, the separation system is fluidly coupled to another separation system.

A filter structure (100) for fuel fluids comprising a first filter wall and a hydrophobic wall, characterised in that the hydrophobic wall is made of a material having a mean static angle that is equal to or greater than 90°, a receding contact angle θ.sub.rec that is less than 90° and a hysteresis H, between an advancing contact angle θ.sub.av and a receding contact angle θ.sub.rec, that is comprised between 50° and 80°.

A filter device may include a filter housing and a filter element defining a longitudinal axis disposed in the filter housing. The filter element may be configured to be penetrated by a fluid flow in a radial direction from a raw end to a pure end of the filter element. A water separator may be disposed at the pure end of the filter element and arranged axially spaced from the same. The water separator may have a hydrophobic and annular diaphragm extending in an axial direction of the filter element configured to be penetrated by the fluid flow from a raw end of the water separator in a radially outward to a radially inward direction with respect to the longitudinal axis to separate water from the fluid flow.

Provided are systems and methods to effect separation of solids from fluid runoff from poultry and produce treatment trains. The systems include separation panels that operate using the Coanda effect so as to effect separation of solids without the need for electricity or moving parts.

A filter element and methods of use and forming are provided. The filter element provides water coalescing and separation functions downstream from particulate filtration functions.
