Method for operating a water system (10). The water system (10) comprises a fresh water subsystem (11) being configured to provide fresh water to water consumers (13, 14, 15, 16, 17, 19), wherein first water consumers (13, 14) generate black water as waste water, and wherein second water consumers (15, 16, 17, 18, 19) generate grey water as waste water. The water system (10) comprises a waste water subsystem (12) being configured to receive the waste water from the water consumers (13, 14, 15, 16, 17, 19). The waste water sub system (12) comprises a waste water diverter (23) being configured to provide in a black water status of the waste water diverter (23) waste water to a drain (24) thereby treating waste water as black water, and provide in a grey water status of the waste water diverter (23) waste water to a grey water tank (22) thereby treating waste water as grey water. The method comprises the following steps: Detect by a fresh water controller (26) being installed in the fresh water subsystem (11) a fresh water consumption in the fresh water subsystem (11) and provide a respective first output signal to a grey water controller (25). Determine by the grey water controller (25) on basis of the first output signal provided by the fresh water controller (26) a control signal for the waste water diverter (23) to switch the same either into the black water status or into the grey water status.

A filter system for filtering a fluid stream is disclosed herein. The filter system includes a first fluid passage, a first chamber, a second chamber, an adsorbing media, and a second fluid passage. The first fluid passage is arranged such that a fluid stream can flow through the first fluid passage and into the filter system. The first chamber is arranged to hold suspended or dissolved solids, pollutants, and nutrients that are filtered from the fluid stream. The second chamber is positioned above the first chamber and in fluid communication with the first chamber. The adsorbing media is positioned in the second chamber. The second fluid passage is arranged such that filtered fluid from the fluid stream can flow out of the filtering system through the second fluid passage.

Plant for desalinating water of a water supply system, which comprises one or more tanks for accumulating water (2) in an immiscible manner, in order to store a softened supply thereof, provided with a first inlet connection (3) and with a first outlet connection (4) respectively connected to a feeding pipe (5) connected to the water supply system (50) and to an extraction pipe (6) for supplying users. The plant (1) also comprises a filtering unit (10) for water softening, for example obtained with a flow-through condenser (10″) or with a reverse osmosis membrane filter (10′), connected in parallel to the tank (2) with second inlet connection (11) and second outlet connection (12) respectively hydraulically connected to the first inlet connection (3) and to the first outlet connection (4) of the tank (2). Circulating means (13) are provided which can be activated to force at least one water flow to be treated to pass through the filtering unit (10), producing a filtered water flow, which is progressively stored in the tank (2) according to a filling direction (VI) thereof. Operatively, the feeding pipe (5) of the water supply system (50) forces, when the user requests water, a water flow intended for use to flow through the tank (2), causing the at least partial evacuation of the filtered water volume that was stored therein in an immiscible manner, in an evacuation direction (V2) opposite the filling direction (VI) with which the filtered water flow had been previously stored in the tank 2.

The liquid purification system comprises a source liquid supply, a purified liquid feed line to a consumer, a liquid purification unit including a liquid-liquid type container consisting of a body containing a storage cavity for purified liquid and a displacement cavity, at least one liquid purification unit, a drainage line and a liquid flow control system including a source liquid feed section and a purified liquid feed section. The liquid flow control system is configured with a source liquid distribution section arranged for maintaining liquid pressure in the displacement cavity intended mainly for source liquid. The system provides the purified liquid feed to the consumer at any stage of the liquid purification process and after the latter is completed.

A water treatment system having a base assembly and a treatment assembly. The treatment assembly of the system may be configured to filter particulates from water. The base assembly may include a UV reactor operable to disinfect water for consumption.

A combined device for sewage deep treatment integrally consists of an open box body (1) divided into multiple water treatment units (29) by a partition wall (27). Each water treatment unit (29) is divided into multiple grids by a partition wall (27′).
