A water recycling apparatus contains: a body, and inflow pipe, a reverse osmosis (RO) discharge pipe, and an outlet pipe. The body includes an accommodation chamber, a first receiving orifice, a second receiving orifice, and a third receiving orifice. The inflow pipe includes a first inlet, a first connection segment, and a first outlet. The RO discharge pipe includes a second inlet, a second connection segment, and a one-way check valve. The one-way check valve has a feeding segment and a discharging segment, such that the RO discharge pipe is connected with the feeding segment of the one-way check valve. The outlet pipe includes a guiding orifice, a third connection segment, and a leading orifice. The body further includes a first layer, a second layer, an inflatable layer, and an air nozzle communicating with the inflatable layer so as to inflate or deflate airs to the inflatable layer.

An apparatus for manufacturing hydrogen-containing water is disclosed. In one aspect, the apparatus includes a container part formed with a upper space and a lower space positioned vertically from each other around a connecting passage therein. The apparatus also includes an ion exchange membrane configured to close the connecting passage and an electrolytic part comprising a cathode disposed on the upper space and a cathode an anode disposed on the lower space. The apparatus further includes a handle part configured to couple to the container part and to provide a supply passage for water to be supplied to the lower space and a discharge passage to discharge oxygen and ozone generated from the lower space.

A proportioning valve for a reverse osmosis system that controls the production of product water by the differential pressure across the purification membrane. By sensing increasing tank pressure to actuate the proportioning valve, the flow of waste water is restricted. Placement of seals within the cavity of the valve, as well as placement of waste water inlet and outlet ports, protects tension components that provide reverse tank pressure from waste water exposure. A needle valve assembly responsive to an actuating assembly that senses tank pressure removes the need for an inlet tank water port while restricting water flow.

A magnetic water filter assembly with a removable lighter weight lower section to permit access to the internal components of the filter assembly. The removable lower section allows the servicing and/or replacement of the internal filter as well as cleaning of the assembly. The lighter weight lower section reduces the stress placed on the surrounding plumbing components, including the piping/tubing that couples to the filter assembly.

In a spacer of an intermediate chamber in an electrolysis vessel, a cathode-side hole that is arranged in a cathode-side grid and an anode-side hole that is arranged in an anode-side grid and is positioned side-by-side with the cathode-side hole with each other in a first direction are misaligned with each other in a second direction that is orthogonal to the first direction. The cathode-side grid and the anode-side grid guide an electrolytic solution flowing into the intermediate chamber from one side of the second direction toward the other side of the second direction while allowing the electrolytic solution to flow along a serpentine course in the first direction by alternately guiding the electrolytic solution to the cathode-side hole and the anode-side hole which are misaligned with each other in the second direction.

An ultrapure water (UPW) generation and verification system can include a cleaning chemical station, a cleanup column, a conductivity verification station, and a holding reservoir, in fluid communication with one another. The cleaning chemical station can be configured to selectably permit a flow of water to pass therethrough to the cleanup column or to block the flow of water and instead deliver a cleaning chemical to the cleanup column. The conductivity verification station can be configured to selectably perform at least one of the following: permit water to flow from the cleanup column to the holding reservoir; direct fluid to waste; or test the conductivity of the water for a purity level.

A device and a method for removing fats, oils and/or grease (“FOGs”) from water comprise a separator, wherein the separator removes the FOGs that separate from the water under gravity, and a filter wherein the filter removes the FOGs remaining in the water after the water has passed through the separator. The filter comprises several layers having different compositions suitable for removing FOGs from water, including a layer comprising granular activated carbon bonded together and wrapped in polyester.

A valve device 3 includes a housing 2 and a valve body 4. The valve body 4 has a first switching position where a first supply port 31 and a first discharge port 33 communicate via an inner flow path 44 and a second supply port 32 and a second discharge port 34 communicate via an outer flow path 45, a second switching position where the first supply port 31 and the second discharge port 34 communicate via the outer flow path 45 and the second supply port 32 and the first discharge port 33 communicate via the inner flow path 44, a third switching position where the first supply port 31 and the first discharge port 33 communicate via the outer flow path 45 and the second supply port 32 and the second discharge port 34 communicate via the inner flow path 44, and a fourth switching position where the first supply port 31 and the second discharge port 34 communicate via the inner flow path 44 and the second supply port 32 and the first discharge port 33 communicate via the outer flow path 45.

Disclosed is a membrane bioreactor (MBR) system. The MBR system according to one embodiment of the present invention includes a membrane filtration tub, a filtration portion including a filter member and installed in the membrane filtration tub, a filtered water storage tank, an air tank configured to store air to be supplied to the filtration portion, a flow channel portion including a first flow channel configured to connect the filtration portion to the filtered water storage tank and a second flow channel configured to connect the filtration portion to the air tank, a valve portion including a first valve located on the first flow channel and configured to open or close the first flow channel and a second valve located on the second flow channel and configured to open or close the second flow channel, and a decompression portion.

A purification device comprises a main body having an opening in a front-face thereof; a rotator disposed in the opening to be rotatably mounted on the main body; a manipulation structure spaced from and above the rotator and rotatably connected to a top face of the main body, the manipulation structure protruding forward of the main body; and a water-outlet including; a first cover fixed to the rotator through the opening, the first cover protruding forward of the main body, and a top of the first cover being connected to a bottom of the manipulation structure; a second cover vertically movable while being held in contact with the first cover; and a nozzle on a bottom of the second cover; wherein when the second cover rises to a highest level, a top of the second cover is located in a space between the rotator and the manipulation structure.
