A transitional water treatment wall for kidney dialysis is provided. The transitional wall includes several devices positioned on a mobile frame, the devices establishing fluid communication between a water source, pre-RO treatment equipment, and an RO system. The transitional water treatment wall also provides pressure and temperature control of the water being circulated. The mobile frame of the transitional water treatment wall includes wheels for providing ease of movement of the transitional water treatment wall. The mobile frame also limits space requirements for the various devices. The transitional wall also includes electrical outlets.

A bottle includes a main body having a receiving cavity, a straw, and a filtering arrangement. The filtering arrangement includes a guider housing disposed in the receiving cavity. The guider housing has a filter cavity, a plurality of liquid input slots communicating the receiving cavity with the filter cavity, and at least one liquid output slot connecting with the straw. The filter core is received in the filter cavity, such that when a suction force is applied through the straw, the liquid in the receiving cavity is arranged to pass through the liquid input slots and contact with the filter core for filtering unwanted substances from the liquid. Filtered liquid from the filter core is arranged to be discharged out of the receiving cavity through the straw.

Devices and methods associated with these devices for significantly improving the efficiency of an existing or new filter having a granular media filter bed. The methods and devices are designed to increase the height and hence overall volume of the filter bed to allow for longer filtration runs between washing or cleaning cycles of the granular media filter bed. One embodiment includes a multi-wash trough adapter that upon removal of an existing deep wash trough connects two shallow wash troughs or two shallow wash trough channels to an existing wash trough opening formed in a wall of a filter compartment. The shallow members have a height significantly less than the height of the existing deep wash trough, e.g., one third to one half of the height of the existing deep wash trough allowing the volume of the granular media filter bed to be significantly increased.

A filter device for filtering water. The device includes a housing, for submersion in a water reservoir, that includes an intake aperture for intake of water from the reservoir and a return aperture for returning water to the reservoir. The housing extends along an axis. The device includes a pump, housed in the housing, arranged on the axis to direct fluid from the intake aperture to the return aperture. The device includes a filter arrangement, housed in the housing, arranged along the axis from the pump in a fluid path between the intake aperture and the return aperture.

A potable water filter for an aircraft galley plumbing system is disclosed. In embodiments, the filter includes a body attachable to a mount via a central threaded attachment stud. The stud is surrounded by a filter mount chamber and encloses a central flow channel allowing outflow from the filter body to an outlet port. Potable water enters the mount through an inlet port; an annular “puck” inlet valve extends around the attachment stud, sealing off the filter mount chamber when the filter body is absent and, when the filter body is screwed onto the attachment stud, providing for water flow throughout the filter mount chamber. The filter body houses a solid block of sintered carbon with a hollow core. Water enters the filter chamber via bypass slots in the base of the filter body and flows around and through the carbon filter before flowing down to the outlet port.

A multi-functional water filtration apparatus includes an outer housing defining a receptacle for receiving a filter assembly and having an inlet port at a first end for intake of unfiltered water and being open at a second end. The filter assembly includes an endcap closing the second end of the outer housing and a filter element enclosed within the outer housing. The endcap has an outlet port for dispensing filtered water. The outer housing has a flow passageway extending between the inlet port and the outlet port. The filter element is disposed in the flow passageway and has an upstream side in fluid communication with the inlet port and a downstream side in fluid communication with the outlet port. In certain aspects, the filtration apparatus provides multiple attachment options. In further aspects, a method of filtering water is provided.

A fluid treatment apparatus and related methods involving the use of replaceable treatment cartridges that include a treatment media, wherein the treatment cartridge is electrically enhanced to form regions of differing polarity within the cartridge. The treatment cartridge can include a pair of fixed polarity conductors that can be electrically connected to a power source so as to induce regions of differing polarity within the cartridge. The fluid treatment apparatus can be utilized to treat liquids including aqueous solutions as well as gases such as an air supply by exposing the fluid to the regions of differing polarity.

A stormwater capture housing system designed to reduce greenhouse gas emissions by filtering solid waste from stormwater flow in roadways, transportation facilities, and pavement, while maintaining an optimal flow rate and enabling safe accessibility. The system comprises a housing unit with top grates that enable stormwater and solid waste to drain from the roadway into a sub-grade capture area formed by a screen weir and a screen box. The screen box ensures that the solid waste is collected while the water filters into a clean water area. The screen weir also filters solid waste and is further configured to allow for an overflow of stormwater and solid waste. Another section of the top wall has a filled grating configuration that allows for stormwater to drain without passing any solid waste to prevent flooding, also enabling access to the internal components of the housing system.

A chemical-agent dosing apparatus for dosing a heating system with chemical agent. The apparatus comprises a chemical-agent storage chamber which stores a chemical agent and a dosing device which has a dosing chamber and a driving means. The dosing chamber is fluidly connected with the storage chamber and defines a dosing volume for receiving a dose of chemical agent. The driving means drives fluid from the dosing chamber via the dose outlet.

The present invention discloses a filtering apparatus for filtering liquid and dispensing the filtered liquid into a bottle separate from the filtering apparatus. The filtering apparatus includes an elongated housing having an interior for holding liquid. The elongated housing includes an opening at one end and a ceiling at another end. The opening encompasses projections extending towards the center of the elongated housing. The filtering apparatus includes a filter configured for insertion and removal from the elongated housing. The elongated housing receives the filter at the interior through the opening. The elongated housing receives a bottle at the opening and the projections hold the bottle at the opening while preventing further entry of the bottle into the interior of the elongated housing. The interior holds liquid and allows the liquid to flow down through the filter. The filter filters the liquid as it flows through. The filtered water enters the bottle for subsequent use, storage or transport.
