A drain for a fuel-water separator (FWS) bowl is disclosed. The drain may include a valve element configured to float in a first fluid and not in a second fluid, wherein the valve element is in a valve element chamber of the drain, wherein the valve element chamber includes an opening configured to drain the first fluid from the valve element chamber, and wherein the valve element seals the opening when the drain is in an open position and when the first fluid has been drained from the valve element chamber; and a member configured to unseal the valve element from the opening when the drain is in a closed position.

The present invention relates to a system and method for providing a filter to prevent contamination of vacuum pumps during use with freeze dryers. The system and method comprising of a vacuum pump connected to a freeze dryer, the vacuum pump evacuating pressure from the freeze dryer; the vacuum pump connected to a coalescing filter at least partially collects water vapor and the particulate gas, whereby the particulates in the particulate gas are at least partially separated from the gas, the coalescing filter further separating the oil from the water and particulates, whereby the oil is rejuvenated for use with the oil composition; an oil control valve to control pressure in the system and maintain a level of oil in the vacuum pump; a drain valve to enable draining of impurities, and a final filter that injects air into oil exchanged between the sedimentary filter and vacuum pump.

There is disclosed a material for separating a liquid from a mixture of at least two liquids, for example, for separating water from fuel. In one embodiment, the material comprises a fibrous substrate and carbon nanotubes, both of which have at least one functional group attached thereto. There is also disclosed a method for separating one liquid from another liquid using the disclosed material. In one embodiment, the method comprises flowing a mixture of liquids through the disclosed material, and either coalescing or separating at least one liquid by use of the carbon nanotubes.

An oil-water separation apparatus is provided which can easily separate and collect oil from a liquid mixture containing water and oil at low cost. The oil-water separation apparatus includes an oil-water-separating member configured to separate a liquid mixture containing water and oil into moisture and oil, and a liquid reservoir subdivided into an upper region and a lower region by the oil-water-separating member. The oil-water separation apparatus filters the liquid mixture by gravity. The oil-water-separating member includes a base which includes a channel for the liquid mixture. The oil-water-separating member is formed in the base, and the oil-water-separating member contains a fluorine compound which has an oil-repellency-imparting group and a hydrophilicity-imparting group. A drain port for discharging the moisture is formed in the lower region of the liquid reservoir.

A contaminant recovery device comprising a container sized to hold a body of contaminated liquid. A skimming arrangement adaptable to at least temporarily remove contaminants from the body of contaminated liquid and an assembly for inducing a flow in at least part of the body of contaminated liquid at or about the skimming arrangement. The skimming arrangement is adaptable to at least temporarily remove contaminants from around the surface of the body of contaminated liquid.

A filter system (200) includes a housing (210) in which a replaceable filter element (100) is arranged between a pre-filtration side (202) and a post-filtration side (204). The filter element (100) has an element-fixed central tube (150), wherein a closure element (10) is provided on a housing side, the closure element (10) opening a post-filtration-side fluid outlet (250) when the filter element (100) has been inserted, and blocking the post-filtration-side fluid outlet (250) when the filter element (100) has been removed. The filter element (100) has an actuating element (160) for the closure element (10).

Methods and devices for treating lipoaspirate for use in fat grafting procedures are provided and generally include a canister for containing lipoaspirate, a separation mechanism structured to separate both oils and other materials from cellular components of lipoaspirate contained in the canister. The separation mechanism includes filters having different filtering capacities, for example, different pore sizes.

The invention relates to a filter element for filtering a fluid passing through the filter element with a group of first channels, in which each first channel extends from a first end to a second end and each first channel has on its first end an inlet opening through which the fluid to be filtered can flow into the respective first channel and is closed at its second end, and a group of second channels, in which each second channel extends from a first end to a second end and each second channel has at its second end an outlet opening through which the filtered fluid can flow out of the respective second channel and is closed at its first end, wherein at least one first channel is arranged adjacent to a second channel and the first channel is separated from the second channel by a partition wall, wherein the partition wall is formed of a filter medium through which the fluid to be filtered can flow from the first channel into the second channel, wherein the filter medium is a coalescence filter medium.

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.
