Abstract:
An in-line fluid purification system uses a jacket (26) surrounding a fluid passageway (28), formed of a UV transmissive material. The jacket (26) may be surrounded by a UV reflective material (30). UV radiation (20) is coupled into the jacket (26), and the jacket (26) disperses and reflects the radiation over the entire cross section of the passageway (28). In this way, UV illumination of the full cross section of a fluid passageway (28) is ensured.
Abstract:
An upright reactor body with a perforated interior tube member which extends for the length of the reactor body. A water inlet permits water to be treated into the perforated tube member. A fibrous metal anode surrounds the perforated tube member followed by a surrounding layer of dielectric and then a surrounding metal cathode layer, wherein water from the inlet passes radially through the perforations in the tube member, through the anode, dielectric and cathode members, emerging from the reactor body through an outlet. A DC voltage is imposed on the cathode and anode.
Abstract:
A rod-shaped electrolysis device having an electrically conductive housing, wherein in the housing, a receiving space for at least one voltage source and an electronic control unit is embodied which is separated from an electrode space formed in the housing in a liquid-tight manner, and wherein an electrode extends within the electrode space, and wherein in the housing, at least one opening is formed in the region of the electrode space. The electrolysis device is characterized in that the housing comprises a receiving socket which is electrically connected both with the housing and the electrode. Via the receiving socket, the residual voltage of a voltage source and also the charging of a rechargeable voltage source may be measured. Furthermore, a data memory may be read out via the receiving socket.

Abstract:
A bioelectrochemical system includes an anode, a saline solution chamber, and a cathode. The anode is at least partially positioned within an anode chamber containing an aqueous reaction mixture including one or more organic compounds and one or more bacteria for oxidizing the organic compounds. The saline solution chamber contains a draw solution and is separated from the anode chamber by a forward osmosis membrane. Water diffuses across the forward osmosis membrane from the aqueous reaction mixture to the draw solution.

Abstract:
The present invention presents a removably secured seal for forming a second stage water-tight seal within a two stage cavity filter head assembly for mating with a complementary manifold having cylindrical (male) bayonet ports. The seal includes a base circumferential seal having a center aperture and sidewall members extending axially upwards from the base seal; the sidewall members being insertable within cavities or slots formed in the second stage recess cylindrical cavity sidewall.
Abstract:
A customizable multi-stage fluid treatment assembly typically includes a connector, a plurality of cartridges, and a cap. The plurality of cartridges have a treatment medium spaced within an interior volume of the individual cartridges, between the ends thereof. The ends of the plurality of cartridges are configured to receive a fluid, bring the fluid into operative contact with the treatment medium, and dispense the fluid from the opposing end of the cartridge. The connector is coupled with one end of the plurality of cartridges and has an inlet and an outlet for receiving and dispensing the fluid to and from an appliance. The cap is coupled with the other end of the plurality of cartridges, enclosing the fluid treatment assembly, which is configured to be received in a cavity of an appliance. The cartridges of the plurality of cartridges may be individually replaced with cartridges to meet customized needs.
Abstract:
A double-pass reverse osmosis (RO) separator module having two stages of RO filtration in a single assembly, including a radially outer RO assembly that surrounds a radially inner RO assembly, wherein each RO assembly includes an RO separation medium. The outer RO assembly may be used for a first-pass of RO filtration in which a first-pass feed liquid enters the outer RO assembly and is separated via reverse-osmosis to provide a permeate liquid and a concentrate liquid. The permeate liquid exiting the outer RO assembly may flow via fluid passages to the inner RO assembly for a second-pass of RO filtration in which the first-pass permeate liquid enters the inner RO assembly as a second-pass feed liquid and is separated via reverse-osmosis to provide a second-pass (i.e., double-filtered) permeate liquid.
Abstract:
A filter unit may include an electrode structure, a fluid-purifying flow path, and a pH adjusting chamber. The electrode structure may include a cathode, a cation exchange membrane, an anion exchange membrane, and an anode in that order. The fluid-purifying flow path may be at least one of a path in the cathode, between the cathode and the cation exchange membrane, between the anion exchange membrane and the anode, and in the anode. The fluid-purifying flow path may include an adsorption function. The pH adjusting chamber may be between the cation exchange membrane and the anion exchange membrane. The pH adjusting chamber may be configured to control the pH of the fluid in the fluid-purifying flow path.
