A manifold assembly and a method of engaging a filter capsule in the manifold assembly are provided.

The present invention relates to a water filter cartridge, with a housing and a flow path for air for ventilating a water tank storing water to be processed by the water filter cartridge. The latter is distinguished in that the flow path has a first water barrier.

Various examples are provided for smart water systems. In one example, a method for providing water through a faucet includes detecting a voice request from a user; providing an indication of the voice request to control circuitry of an electrically operated valve coupled to a water supply line of the faucet; and activating the electrically operated valve to provide water through the faucet. In another example, a method includes detecting a request for water from a user; providing an indication of the request to control circuitry of an electrically operated valve coupled to a water supply line of the faucet; and activating the electrically operated valve to provide a specified amount of water through the faucet.

Disclosed herein is a water purifying system, including: a raw water tank configured to store raw water; a filter unit configured to include a plurality of filtration modules for purifying the raw water and a plurality of valves for feeding or cutting off the raw water; a raw water pump configured to feed the raw water from the raw water tank to the filter unit; and a backwash module configured to feed backwash water to the filter unit, in which some of permeate water permeated by the filter unit is fed to the backwash module to be used as the backwash water and a feed pressure of the backwash water is fed by the raw water pump.

A filter assembly has a housing with a housing inlet and a drain. A rotary vessel is rotatably mounted within the housing and has a rotary vessel inlet and a rotary vessel outlet. Fluid exiting the rotary vessel outlet exits the housing through the drain. A valve assembly moveable between a closed and an open configuration is provided. When closed, the valve assembly fluid-tightly seals rotary vessel inlet from housing inlet. When open, the rotary vessel inlet is in fluid communication with the housing inlet such that fluid flowing into the housing inlet passes into the rotary vessel inlet. The valve assembly is moveable from closed to open configuration when a pressure of fluid flowing into the housing inlet exceeds a threshold pressure. The filter assembly has a fluid passageway permitting air flow into the rotary vessel through the rotary vessel inlet when the valve assembly is closed.

The invention relates to a particle filter device (1) comprising: a fluid inlet (20), a fluid outlet (21), a first fluid flow circuit (31) comprising a first filter zone (2) having a first filter surface (S.sub.1), a second fluid flow circuit (32) comprising a second filter zone (3) having a second filter surface (S.sub.2) and a constriction (4) having a constant hydraulic resistance so that, in operation, a first portion of the fluid flows through the first flow circuit (31) by passing through the first filter zone (2) and a second portion of the fluid flows through the second flow circuit (32) by passing through the second filter zone (3) and the constriction (4), and the first filter zone (2) reaches a predetermined clogging condition before the second filter zone (3).

A filter arrangement for an aquarium is disclosed. The filter arrangement can include a filter housing assembly, a pump assembly, and a transfer tube assembly. In one aspect, the housing assembly and the pump assembly are separately constructed assemblies that are connected to each other via a first dampening member to prevent vibration and sound from being transmitted from the pump assembly to the filter housing assembly. The filter arrangement can further include a second dampening member connecting the pump assembly with the transfer tube assembly to further prevent vibration and sound from being transmitted from the pump assembly to the filter housing assembly. A third dampening member can be provided at a location where the transfer tube assembly is supported within the filter housing assembly to further isolate vibration and sound from being transmitted from the pump assembly to the filter housing assembly via the transfer tube assembly.
