The present invention relates to systems incorporating, and uses of, hydrothermally dehydrated carbonaceous products, particularly from waste sources, that when activated provide for effective filters in water streams. The activated particles have high microporosity and provide an improved and affordable approach to decontamination of water sources. The invention further includes preparation of such systems, including steps of hydrothermal dehydration, optional carbonization, and physical activation.

A floating dispenser holder having a platform supporting a dispensing cartridge in a dispensing condition and a canopy extending over the dispensing cartridge located on the platform.

An illustrative expendable or reconstructable ozone generator cartridge for an aqueous ozone delivery device, for example, for antimicrobial sanitizing and/or medical treatment, includes a housing for a water ozonating manifold, at least one ozone generating cell coupled to the manifold, and optionally a data logging and authentication feature. Advantageously, a water inlet, an aqueous ozone outlet, and an electrical connector of the ozone generator cartridge are simultaneously pluggable into and unpluggable from a docking station of the aqueous ozone delivery device, for example, a hand or implement washing and sanitizing device or a medical treatment device.

A car washing system comprises a filtering unit, a pure water pipeline, a waste water pipeline, a washing pipeline, an optional first branch line, and a second branch line. The filtering unit comprises an RO filter membrane, a filtering pipeline and a booster pump. One end of the filtering pipeline is connected to the inlet of the RO filter membrane. The booster pump is set in the filtering pipeline. The pure water pipeline is connected between a pure water outlet of the RO filter membrane and one end of the washing pipeline. The joint of the pure water pipeline and the washing pipeline is provided with a high-pressure pump. One end of the waste water pipeline is connected with waste water outlet of the RO filtering membrane, and the other end is a discharge end. The second branch line is connected between the waste water pipeline and the washing pipeline.

A filter cartridge for a whole house water filter includes a cylindrical, or tubular, filter media coupled to a mixer tank with improved high flow mixing features. The mixer tank includes a bowl in which a flow diverter, a flow guide with angled fins and a filter media are provided. The flow diverter has a concave portion, i.e., a mushroom-shaped portion, the interior of which is in fluid connection with a central passage through which filtered water flows. In operation, the filtered water flows through the central passage and is deflected by the concave interior of the flow diverter down through the angled fins of the flow guide. The filtered water then passes out through an outlet. The mixer tank stirs the filter media and water mix to increase the kinetics of the mixing process.

A water treatment system having a base assembly and a treatment assembly. The treatment assembly of the system may be configured to filter particulates from water. The base assembly may include a UV reactor operable to disinfect water for consumption.

A water filter system with a filter housing, a filter media, a filter coupling, and a dynamic seal. The filter housing has a top plate and a bottom plate which are both water-permeable, as well as a cavity between the top plate and the bottom plate. The filter media is within the cavity of the filter housing and extends through the bottom plate of the filter housing. The filter coupling extends upward from the top plate and is configured to attach to a float with at least one air chamber. The dynamic seal is coupled to the filter housing along a perimeter of the filter housing and is configured to extend beyond a perimeter of the float, maintain contact with a wall of a water container, and restrict water from passing between the dynamic seal and the wall of the water container.

The cooling device for a power source for a ship propulsion device that pumps up cooling water, from which foreign matters with sizes that cause clogging of a cooling water route have been removed, supplies the cooling water to a cooling water passage (30), and discharges the cooling water to outside after cooling a power source (10) includes: a cartridge-type filtration device (40, 73) that is provided at a midpoint of a first water passage (36, 71) in the cooling water route and incorporates a filter (45, 46) for filtrating foreign matters remaining in the cooling water; and a second water passage (38, 72) that is branched from the first water passage and adapted such that a valve member (53) is opened to cause the cooling water to flow in a case in which clogging occurs in the filter.

A water filter cartridge includes a sediment filter, a carbon filter, and a core having a tubular body with openings that allow water to flow through the core. The core defines an open central area, and the core supports the sediment filter and the carbon filter. A nanofiltration unit is arranged within the open central area of the core. The nanofiltration unit includes a tubular filter element defining a central volume, and a plurality of filaments arranged within the central volume.

A water purifier includes a filter head, a flow channel control module, and a filter element. The flow channel control module includes a waterway board and a flow manifold. The waterway board is provided with a water flow channel. The flow manifold is provided with a first passage and a second passage. When the flow manifold is driven by the filter element and rotated relative to the waterway board to a first position where the first passage is connected to the water flow channel, the flow channel control module is switched to a first flow channel waterway mode (or filter mode). When the flow manifold is driven by the filter element and rotated to a second position where the second passage is connected to the water flow channel, the flow channel control module is switched to a second flow channel waterway mode (or replacement mode).
