A water-dispensing device includes a source water intake, a spigot, and first and second filters arranged between the intake and the spigot. The first filter includes a first inlet and outlet. At least the first inlet includes a first electrically controlled valve for selectively placing the first filter in fluid communication with the intake. The second filter includes a second inlet and outlet. At least the second inlet includes a second electrically controlled valve for selectively placing the second filter in fluid communication with the intake. A controller is configured to: (i) receive a water selection from a user, and (ii) configure the first and second valves based on the selection such that water flowing from the intake toward the spigot will enter any of the first and second filters corresponding to the selection and bypass any of the first and second filters that do not correspond to the selection.

The invention relates to preventing microplastics from the entering the environment. In particular the invention is directed to filtering microfibers from the waste water from washing machines as well as waste from other appliances and other sources of effluent with entrained microplastics or other microp-ollutants. A separator is provided for separating microplastics from effluent comprising; a chamber including at least one sieve structure, a shroud that acts as a vortex finder and a baffle coaxial with the shroud and projecting upwards from the lower end of the chamber, wherein the shroud has a circular lower rim and the baffle has a circular upper rim, wherein the radius of the lower rim of the shroud is greater than the radius of the upper rim of the baffle.

A stripping-solution machine and working method thereof are provided. The stripping-solution machine includes: a plurality stages of chambers, which are arranged sequentially in order, wherein each stage of the chamber is correspondingly connected to a storage box; at least one filter device, wherein one end of the filter device is disposed to be connected to a storage box corresponding to a current stage chamber by a first pipe, and another end of the filter device is connected to a next stage chamber by a second pipe. Furthermore, a plurality of valve switches are at least disposed on the first pipe or the second pipe.

The disclosed technology includes systems and methods for water filtration. In one implementation, a system includes a water receptacle to house unfiltered water, the receptacle including an aperture located in a sidewall, a valve component located on an exterior surface of the sidewall in alignment with a filter housing located on an interior surface of the sidewall filtrate the unfiltered water. In one implementation, a method includes filling a water receptacle with unfiltered water, filtrating the unfiltered water through a filter housing in the water receptacle to obtain filtered water, and moving the filtered water from the filter housing and out of a valve component connected to a first end of a filter housing.

There is provided a filter for a diaphragm valve. The filter attaches to a diaphragm of the valve and filters fluid entering a control chamber in the valve. The filter includes internal structure that increases the path from where fluid enters the filter through a mesh of holes to a single exit flow path leading to the control chamber. This increased path reduces the potential for debris in the flow to clog the exit flow path from the filter.

Embodiments of the invention provide a liquid fill kit system including a rollable cart having a frame and a plurality of wheels. A tank disposed within the frame. The fill kit further includes a fluid pump including a suction interface connection and a discharge interface connection. A filter assembly mounted within the frame. A fluid pressure regulator include a fluid outlet port, the fluid pressure regulator being configured to stop a flow of fluid when a pressure exceeds a fluid pressure threshold. In a first configuration, the suction interface connection is in fluid communication with the tank, and the discharge interface connection is in fluid communication with the filter unit, the pressure regulator, and the fluid outlet port to generate a flow of fluid through the fluid outlet port.
