A water purifying apparatus including a head having a water inlet portion and a water outlet portion; a shaft provided in the head and rotatably mounted between the water inlet portion and the water outlet portion; a bypass flow path passing through a circumference of the shaft, and communicating the water inlet portion with the water outlet portion according to rotation of the shaft; a filter detachably mounted to the head, and having a filter inserting portion in which the shaft is inserted when being mounted on the head; and a filtering flow path in which an inlet port and an outlet port are formed on the circumference of the shaft in a direction intersecting the bypass flow path, and communicated between the filter, the water inlet portion and the water outlet portion with each other according to the rotation of the shaft.

The present invention relates to a water filter cartridge, with a housing and a flow path for air for ventilating a water tank storing water to be processed by the water filter cartridge. The latter is distinguished in that shut-off means are provided for the flow path for air, preferably in the form of a valve or a membrane.

The present invention relates to an electrolysis body suitable for water disinfection for use in a water reservoir having a definite internal volume comprising a) a pair of electrodes made of a conductive material suitable for providing electrolysis, b) means for applying current to the electrodes, c) an insert unit having a first side and a second side opposite each other, wherein the first side faces out of the water reservoir when the insert unit is placed in position in the water reservoir in use for water disinfection and the second side faces into the volume of the water reservoir when placed in position in the water reservoir in use for water disinfection, and d) optionally a filter unit extending from the second side of the insert unit. The present invention also concerns a water reservoir comprising the body, as well as a washing system comprising the water reservoir.

A fluid purification system capable of removing lead from significant volumes of fluids also containing at least one of TOC and TTHM under low pressure conditions and at reasonable flow rates is provided. The system comprises a first fluid purification media comprising a rigid porous purification block. The rigid purification block includes a longitudinal first surface; a longitudinal second surface disposed inside the longitudinal first surface; and a porous high density polymer disposed between the longitudinal first surface and the longitudinal second surface. The system further includes a second fluid purification media, comprising a fibrous, nonwoven fabric disposed adjacent to the first surface of the first fluid purification media, the second surface of the first purification media, or both.

A fluid treatment system is provided, comprising a capacitive deionization (CapDI) system for removing dissolved solids from a fluid. A controller is arranged in a closed feedback loop with the CapDI system to verify whether measured conductivity of the fluid corresponds to a set point conductivity value, and if the measured conductivity of the fluid does not correspond to the set point conductivity value, adjust the operation of the CapDI system to match the set point conductivity value. A pump selectively pressurizes the fluid such that purified fluid is at a pressure greater than line pressure of the fluid treatment system. An accumulator provided downstream of the CapDI system maintains the purified fluid at a pressure greater than the line pressure and intermittently delivers purified fluid to a use device. The purified fluid stored in the accumulator comprising chlorine and or chloramine so as to reduce microbial growth when stored in the accumulator.

The present invention describes a system comprising a water recirculation device 1 allowing for purification and recycling of water or separation of water, said water recirculation device 1 comprising a water treatment unit 2 and a sensor system 3 arranged for measurement of at least water quality and which sensor system 3 is connected to a control unit, and wherein the system also comprises at least two separation points, wherein one first separation point 30 is positioned within the water recirculation device 1 to allow for recirculation of clean water or separation of a first separated stream of water not intended to be recirculated in the water recirculation device 1, and wherein one second separation point 30 is arranged for separation of the first separated stream of water in at least one high quality water stream and in one low quality water stream, and wherein a decision of recirculation or separation is made by the control unit based on the measurement of water quality.

The present invention discloses a side-leakage-proof and environmentally-friendly filter element, which relates to the technical field of filter elements; an inner side-leakage-proof layer is fixedly installed on an inner side wall of the skeleton supporting layer, an upper end of the inner side-leakage-proof layer is provided with a water-entry netting, the water-entry netting is fixedly installed at an upper end of the skeleton supporting layer, an inner upper side of the inner side-leakage-proof layer is filled with the first filter material, an inner lower side of the inner side-leakage-proof layer are filled with the second filter material, the bottom middle part of the inner side-leakage-proof layer is provided with a water outlet slot. The present invention can prevent side leakage of water along the outer wall side before filtering, improve the use efficiency of filter material and have high stability; and the present invention has high strength, is not easy to deform, at the same time realizes energy saving and environmental protection, and the service life thereof can be prolonged.
