A water use management system may be installed in a setting that contains a primary infrastructure for water use to provide an alternate, modular infrastructure for water use. Fresh water used at various points of use, such as a shower or sink, may be diverted into the modular infrastructure prior to draining into the primary infrastructure. Once diverted, the precedent use water is received at a reservoir system where it is treated for a subsequent use. Treatment may include filtration and/or chemical treatment, and may be based upon sensor feedback from the reservoir system. Once treated, the water is ready for subsequent use and may flow from the reservoir system, via the modular infrastructure, to a subsequent point of use, such as a toilet.

A dishwasher including: a cleaning chamber; a water tank which stores water in order to supply water to the cleaning chamber; a water softener which is connected to the water tank and to which a filter is mountable; and a regenerator which is connected to the water softener in order to regenerate the filter while the filter is mounted to the water softener, wherein the water tank comprises a softened water chamber that is supplied with water that has been softened in the water softener and stores same, and a recycled water chamber which receives softened water from the softened water chamber and is connected to the regenerator in order to supply water to the regenerator.

A filter cartridge assembly for an ice making appliance having a rectilinear filter cartridge with a plurality of partitions that are positioned within an internal chamber, form multiple sub-chambers, and create a non-linear pathway for the flow of water through the filter cartridge. Filter media positioned in the sub-chambers of the filter cartridge are configured to remove dissolved solids from water travelling through the filter cartridge and used by the appliance to create ice, including clear ice.

A filter base for receiving a mating filter housing assembly having a base platform having fluid ingress and egress stanchions, and a wire harness assembly including a connector housing integral with or connected to the base platform for establishing an electrical connection between the filter base and the mating filter housing assembly. The wire harness assembly having conductors extending between first and second connectors, with one or more resilient contacts provided on the second connector. The contacts are flexible from a first position to a second position when curved contact sections of the one or more contacts engage a mating connection surface of the complementary mating filter housing assembly. The mating connection surface may be a circuit pad of a printed circuit board, wherein the contact curved contact sections are configured to be positioned in mechanical and electrical engagement with the circuit pads when the filter housing assembly is received within the filter base.

A system including a tube for transferring fluid, a fiber optic cable that extends through an interior of the tube, and a light source configured to project high intensity narrow spectrum light into the fiber optic cable.

A water purifying apparatus includes a head that is configured to couple to a filter and defines a water inlet and a water outlet, and a shaft provided inside the head, rotatably mounted between the water inlet and the water outlet, and having a filtering passage configured to connect the water inlet to the water outlet so that water introduced into the water inlet is discharged to the water outlet via the filter. The shaft includes a shaft inlet and a shaft outlet, which are opened to respectively communicate with the water inlet and the water outlet so as to define the filtering passage, and a water inlet blocking portion and a water outlet blocking portion, which are provided between the shaft inlet and the shaft outlet to shield opened surfaces of the water inlet and the water outlet.

A reactor that operates with ultraviolet light emitting diodes (UV-LEDs) to attain UV photoreactions or UV photo-initiated reaction in a fluid flow for various applications, including water purification. The UV-LED reactor is comprised of a conduit means for passing fluid flow, an ultraviolet light emitting diode (UV-LED), and a radiation-focusing element to focus the UV-LED radiation to the fluid in the longitudinal direction of the conduit. The UV-LED reactor may include photocatalysts or chemical oxidants, which are activated by UV emitted by UV-LEDs for photocatalytic and photo-initiated reactions.

A flocculation system is provided including a vessel having an open top. The flocculation system also includes a sidewall comprised of a water-impermeable material. The flocculation system further includes a first bottom comprising the water-impermeable material. The flocculation system further includes a second bottom having a floc filter that passes flocs and prevents the passage of a cleaning tool. The flocculation system further includes a floc trap below the second bottom. The floc trap includes a space defined by the sidewall, the first bottom, and the floc filter. In some implementations, the flocculation system includes a flocculant disposed on the sidewall, the floc filter, or the first bottom.

A flocculation filter is provided. The flocculation filter includes a filter layer having openings that pass water and trap flocs is provided. The flocculation filter also includes a flocculant layer disposed on at least a portion of the filter layer.

The present disclosure relates to an automatic control system and method for water treatment of a thermal sterilization kettle. The system comprises a sampling module, a monitoring module and a control module, wherein the sampling module is used for respectively sampling hot water and cold water, and the monitoring module is arranged to respectively monitor online fluorescence signals in the sampled hot water and the sampled cold water; the control module is used for respectively controlling whether to add a compound medicament into a hot water area or not according to the online fluorescence signal of the sampled hot water and controlling whether to add the compound medicament into a cold water area or not according to the online fluorescence signal of the sampled cold water; and meanwhile, the monitoring module is further used for monitoring the residual chlorine signal of the sampled cold water.
