A filter assembly and method of filtering wastewater from a washing machine. The filter has a framework for supporting a first filter stage and a second filter stage, a connection on a top of the filter assembly for connecting to a wastewater stream, a diffuser positioned to extend into the first filter stage and configured to rotate about a vertical axis of installation within the first filter stage, and a second filter stage below the first filter stage and configured to receive overflow from the first filter stage. The filter assembly does not include a motor or motorized parts and wherein the diffuser is rotatable by way of the force of the wastewater stream fed into the first filter stage to diffuse the wastewater stream and to spray the wastewater onto and through the filter media allowing the filter media to catch debris within the first filter stage.

Apparatuses for dispensing household fluids including a handheld device or wand including a pump for dispensing one or more household fluids at a rate and for a time sufficient to dispense a pre-determined or variable amount of the fluids into an appliance, and to methods for making and using same. Apparatuses for dispensing pool chemicals including pool chemical containers, pool chemical sensors, and pumps for introducing pool chemical into pool water on a periodically basis.

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.

A sterilization apparatus includes a light source unit for emitting light to a sterilization region for sterilizing a target particle, a power supply unit for supplying power to the light source unit, and a photodiode unit for sensing the light from the light source unit. The photodiode unit is driven by the light from the light source unit.

A versatile sanitizing and cleaning apparatus (10) has a reservoir (30), a removable base (40) at the bottom of the reservoir having electrodes (52, 54) that extend up into the reservoir (30) for electrolyzing water within the reservoir, and an opening (32) at the top end of the reservoir. A cap (60) having a valve (61) that is biased to the normally-closed position screws to the top of the reservoir (30), allowing the reservoir to be turned upside-down and inserted into a receiving portion (22) of a mop, thus allowing the mop (12) to use electrolyzed water for cleaning. Alternatively, instead of being used with the cap (60) and mop (12), the reservoir (30) and base (40) can be mated with a hand sprayer (64) allowing the reservoir (30), base (40), and hand sprayer (64) to be used as a spray bottle (69) to spray electrolyzed water for cleaning purposes.

A neutralization cell is provided which may be used to increase a pH level of a chlorine solution. The neutralization cell includes a neutralization anode, a neutralization cathode, an inlet, and an outlet. The neutralization anode and the neutralization cathode are positioned to divide the neutralization cell into a middle area between the neutralization anode and the neutralization cathode, an anode area on a side of the neutralization anode furthest from the neutralization cathode, and a cathode area on a side of the neutralization cathode furthest from the neutralization anode. The inlet directs the chlorine solution into the neutralization cell by directing an incoming flow of the chlorine solution into the anode area. The outlet directs the chlorine solution out of the neutralization cell by directing an outgoing flow of the chlorine solution from the cathode area.

The present invention relates to a water treatment apparatus (1), in particular for supplying water-conducting and/or water-heating household appliances or appliances for producing and preparing food and/or beverages using treated drinking water, e.g. automatic drinks machines, automatic coffee machines, ice machines, cooking and baking appliances, steam generators or high-pressure cleaners, air conditioners or the like using treated water, comprising an agent (3) present in solid form for reducing mineral precipitates. It is characterized in that a first medium which influences the dissolution behavior of the agent for reducing mineral precipitates is provided.

A water sterilization module includes a container including a water inlet and a water outlet and containing water therein, and a light source part mounted on a part of the container and irradiating sterilizing light into the container. The water inlet has a diameter larger than a diameter of the water outlet.

A dishwashing method in which water having an oxidizing and disinfecting action is provided in a dishwasher and used as dishwashing water or added to a dishwashing water, wherein, to provide the water, a) a stream of untreated water is fed into a reverse osmosis device and separated into a concentrate stream and a permeate stream, b) ozone is produced by an ozone generator, and c) the ozone is introduced into the permeate stream emerging from the reverse osmosis device, wherein the reverse osmosis controls ozone production in that the ozone generator is configured such that ozone is only produced and mixed with the permeate stream when the reverse osmosis device is in operation.

An apparatus for reducing emulsions in kitchen effluent discharging to a FOG removal apparatus includes a pre-rinse sink, a tank positioned below the pre-rinse sink to receive effluent from the pre-rinse sink, an outlet from the tank and leading to a pipe, a valve in the outlet having an open position and a closed position, a dishwasher having a drain connected to the pipe, and a control for the valve to be in its closed position when the dishwasher is discharging to the pipe.
