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.

Provided is a water purifier including: a raw water flow path into which water flows from outside; a filter configured to filter the water introduced from the raw water flow path; a purified water flow path configured to discharge the water having passed through the filter; a drain flow path through the water discharged from the filter through the wastewater flow path is discharged; a resistance valve configured to reduce a flow rate of the drain flow path; a first connection flow path connecting the raw water flow path to a downstream side of the resistance valve on the drain flow path; a second connection flow path connecting the purified water flow path to an upstream side of the resistance valve on the drain flow path; and a tank arranged on the second connection flow path. During washing of the filter, the water stored in the tank flows into the filter via the upstream side of the resistance valve on the drain flow path, and the water flowing into and through the filter is discharged to the outside through the raw water flow path, the first connection flow path, and the downstream side of the resistance valve on the drain flow path.

The system is formed from a housing (1), wherein one or more water inlets and outlets (2) are established, and one or more treated air outlets (7), with means for regulating the flow of incoming water, and which has branches whereto a pneumatic injection unit (3) associated with one or more equipment (38)-(38b) generating oxidising and disinfecting gases is connected. The circuit has a non-return valve (9), overpressure safety valves (10), automatic and/or manual closing and opening means, water and air flow and pressure sensors (16), as well as one or more external connections (12) to take the air or gas of the adapted oxidation technology to the desired remote area to be treated, all with a control interface associated with one or more meters or electronic regulatory systems (17) of the amounts of air or gas to be injected into the system.

A foreign object protection system for dishwashers is disclosed. The foreign object protection system prevents large objects from damaging other components of a dishwasher. An example dishwasher for treating dishes according to a cycle of operation includes a tub at least partially defining a treating chamber for receiving utensils for treatment according to the at least one automatic cycle of operation, a sump fluidly coupled to the tub and collecting liquid supplied to the tub, a recirculation pump having an inlet fluidly coupled to the sump and an outlet fluidly coupled to the tub to recirculate liquid from the sump to the treating chamber; and a foreign object protection system comprising an inclined grate, and fluidly separating the sump and the outlet; wherein liquid in the tub collects in the sump and is recirculated by actuating the recirculation pump such that the liquid in the sump is drawn through the foreign object screen and expelled through the outlet to the tub and the foreign object screen protects the recirculation pump from harmful objects.

A modular liquid waste treatment system is disclosed. In accordance with some embodiments, the system includes a central distribution unit and one or more treatment fins in flow communication therewith. The distribution unit may be configured to receive liquid waste from a given source and distribute that waste, at least in part, to one or more treatment fins. In turn, bacteria present in a given treatment fin treat the liquid waste, and the resultant treated liquid may drain from the fin to the surrounding environment. In some embodiments, a given treatment fin may include porous media providing a large surface area on which bacteria may grow to facilitate treatment. The system may be installed in and/or above the ground, and in some cases may be surrounded, at least in part, with treatment sand and/or other treatment media. The system may be used in aerobic and/or anaerobic processing of liquid waste.

A waste water treatment system and method for use with a septic tank includes sequentially executing the steps of aerating waste water in the septic tank for a first period of time with an air diffuser, allowing the waste water to sediment for a second period of time, and pumping purified waste water out of the septic tank for a third period of time.

A waste treatment system may include a liquid separator for removing water from solid waste, a mixing tank connected to the liquid separator for mixing the solid waste with an oxidizing agent, a heat exchanger connected to the mixing tank for collecting heat generated by an exothermic reaction caused by mixing the oxidizing agent with the solid waste, and a sanitizer connected to the liquid separator to sanitize the water removed from the solid waste. A waste treatment method may involve separating water from solid waste in a liquid separator, mixing the solid waste from the liquid separator with an oxidizing agent in a mixing tank connected to the liquid separator to cause an exothermic reaction, collecting heat from the exothermic reaction in a heat exchanger coupled with the mixing tank, and sanitizing the water from the liquid separator in a sanitizer.

A method and associated system for processing waste gases, liquids and solids, produced by human activity, to separate (i) liquids suitable for processing to produce potable water, (ii) solids and liquids suitable for construction of walls suitable for enclosing a habitat volume and for radiation shielding, and (iii) other fluids and solids that are not suitable for processing. A forward osmosis process and a reverse osmosis process are sequentially combined to reduce fouling and to permit accumulation of different processable substances. The invention may be used for long term life support of human activity.

Apparatuses for treating radioactive material using a multi-membrane are disclosed. The apparatus for treating radioactive material uses a multi-membrane capable of increasing the usage capacity and life of the storage tank with a multi-membrane process by discharging liquid (e.g., water in waste water) in which radioactive material is removed from waste water to the outside and by storing solidified waste containing radioactive material in the storage tank.

The present invention relates to a treatment system, apparatus, assembly, facility, cycle and/or method for the treatment of water or wastewater, in particular, a system, apparatus, assembly, facility, cycle and/or method for treating water or wastewater received at high flowrates (including in excess of approximately 200 L/min) through a series of two or more dissolved air flotation chambers.
