The present invention describes a water filter apparatus (100, 100a) with integrated nutrient enrichment and/or enhancement. Desired nutrients, ions, hydrogen ions, ceramic, stones, metal etc. packed in granules or balls are selectively disposed inside a stick capsule (160), shell capsule (180) or hydrogen capsule (190). One or two stick capsules (160) are located inside a filter element (150). The stick capsule has a tapered end (162) and in association with T-shaped posts (157) formed on an inside of a cap (151) of the filter element, dynamic flow of water along the tapered end (162) induces nutrient-rich water to flow through perforations (165) at the end of the stick capsule (160), mixes/blends the two streams of water before water is discharged through a faucet (144). The filtered water is also enhanced by treating the water through flavor treatment, anti-bacterial, anti-chlorine, activated carbon and so on.

A vehicle includes a water collection system including a deployable channel movable between a stowed position and a deployed position for capturing water, a filter for filtering the water collected by the deployable channel, and a tank for storing the water filtered by the filter.

A coolant liquid processing system includes: a filtration device for filtering a coolant liquid containing sludge; and a detector that detects particles in a treatment liquid filtered by the filtration device.

A filter element for liquid filtration has a hollow-cylindrical filter medium body and an end disk covering an end face of the filter medium body. A central cutout axially penetrates the end disk. An outflow channel for liquid to be filtered or filtered liquid is arranged at the end disk and connects to a liquid collecting space. The outflow channel extends from a radially outward wall surface of the filter medium body to the central cutout of the end disk. The outflow channel is controlled by a drainage device. A filter device with a filter housing provided with such a filter element has a drainage device that controls the outflow channel. A filter device with a drainage device having a first drainage position for draining only water and a second drainage position draining water from a water collecting space and liquid from a liquid collecting space is provided.

A fuel filter has a separating device separating, from a medium flow comprising a first medium and a second medium, the first medium as a separated first medium contaminated with the second medium. The fuel filter has a cleaning device receiving a proportion of the second medium contained in the separated first medium. The cleaning device is arranged upstream of a discharge opening for discharging the first medium from the fuel filter. The cleaning device is provided with an absorbent/adsorbent cleaning material. The cleaning material contains or is made of an organoclay as an active component. The organoclay is a bulk material, wherein at least 50 wt. % of the organoclay has an average particle diameter of greater than 50 m and smaller than 1,000 m.

A separating device for separating an undesired fluid from a multi-component liquid has a region flowed through by the multi-component liquid and at least one membrane disposed in the region to separate a first fluid region from a second fluid region. The membrane has a first permeability to the undesired fluid and a second permeability to the multi-component liquid. The first permeability is different from the second permeability. The membrane is equally permeable to all components of the multi-component liquid. The membrane is permeable to the multi-component liquid and impermeable to the undesired fluid, or the membrane is impermeable to the multi-component liquid and is permeable to the undesired fluid, wherein the multi-component liquid is a liquid multi-component operating medium. A filter with such a separating device and a filter element, in particular for diesel fuel, as well as a liquid system with such a separating device are described.

A multifunctional filter valve is provided. The multifunctional filter valve includes a valve body, a rotatable valve plate, a fixed valve plate, and a driving device. A water inlet, a water outlet, and a drainage outlet are disposed on a side wall of the valve body. The water outlet is configured to connect to a valve. An inner chamber and an outer chamber are defined in the valve body. The inner chamber defines a central drainage chamber, a working chamber, a backward washing chamber, and a blind chamber. A first filter element interface and a second filter element interface are defined at a bottom of the valve body. The combination of fixed valve plate and rotatable valve plate achieves a normal operation mode, a backward washing mode, and a forward washing mode. The multifunctional filter valve has a simpler structure and lower production cost.

The disclosure relates to a fuel filter assembly, a filter element, and a method of draining water from a fuel filter assembly. The fuel filter assembly comprises a filter element with a water collecting space; the filter element being connected to a fuel pipe for feeding an upstream side of the filter element with fuel and for providing filtered fuel from a downstream side of the filter element to a combustion engine or parts thereof; a fuel pump arranged downstream from the filter element, wherein the fuel pump can be operated in a first mode for drawing fuel through the filter element and in a second, reverse mode for feeding fuel back to the filter element; a one-way fuel valve arranged upstream of the filter element allowing for flow towards the upstream side of the filter element; a pressure-actuated one-way drain valve in communication with the water collecting space.

A filtration assembly filters diesel fuel used by a diesel engine and includes a filter element disposed within a housing. The housing includes an unfiltered fuel inlet and a filtered fuel outlet. The filter element disposed within the housing receives fuel from the fuel inlet. The filter element defines a peripheral wall sealably engaging filter media defining an unfiltered side and a filtered side of the filter element. The unfiltered side is enclosed with an impermeable barrier affixed to the peripheral wall and the filtered side is enclosed with a permeable water diffuser through which filtered fuel passes. A water separator assembly is disposed externally to the filter element receiving filtered fuel from the water diffuser. The water separator assembly includes water separator media preventing water from passing into the separator. The separator assembly interconnects to the filtered fuel outlet providing filtered, dewatered diesel fuel to the diesel engine.

A system for preparing nanoparticles by supercritical hydrothermal synthesis is provided. Firstly, a mixture of a first reactant and a second reactant and high-temperature water at an outlet of a heating furnace (10) are mixed and are heated to a reaction temperature, the mixture is connected to a supercritical hydrothermal synthesis reactor (14), and a product at an outlet of the supercritical hydrothermal synthesis reactor enters a heat regenerator (9); hot water at an outlet of a low-temperature section of the heating furnace (10) first enters the heat regenerator, and then enters a high-temperature section of the heating furnace so as to be continuously heated to a set temperature; fluid at the pipe side outlet of the heat regenerator separately passes through a heat exchange coil in a first reactant modulation pool (1) and a steam generator (2) in a waste heat power generation system (20).
