An apparatus for cleaning pool or spa filters includes: a housing; a turntable assembly in the housing, the turntable assembly configured to receive a filter thereon; and a fluid assembly on the housing configured to receive liquid from a liquid source. The fluid assembly includes: a spin jet configured to spray the liquid on the turntable such that the turntable and the filter thereon spin; and at least one power jet configured to spray the liquid on and/or through the filter while the turntable assembly and the filter spin.

A liquid filtration system comprising a filtration tank with: a separating roof on which are mounted groups of hoses fixed to respective support plates; a fluid distributor plate comprising a central portion without perforations, and a peripheral portion with a plurality of perforations, said distributor plate being located between the hoses and a lower inlet duct for the water to be filtered comprising an upper opening for supplying liquid to the holes near the central portion of the distributor plate and a lower opening for supplying liquid to the holes of the peripheral portion which are furthest from the central portion. The filter comprises a filter material, an outlet duct for the filtered water at the upper area of the tank, a regeneration circuit of the filter medium; a filter self-cleaning circuit and a control panel.

Proposed is a fines removal apparatus installed on a radioactive liquid waste granulator, the apparatus including: a body unit fastened to an outlet provided on the radioactive liquid waste granulator and configured to receive the granulated radioactive waste by an operation of a first opening/closing valve, the radioactive liquid waste granulator being configured to manufacture concentrated liquid waste and to manufacture granulated radioactive waste by drying the concentrated liquid waste. an air supply unit provided on one side of the body unit and configured to spray air to the supplied granulated radioactive waste at regular periods, thereby scattering and separating fines contained in the granulated radioactive waste; and a reprocessing unit provided in a vacuum state on an opposite side of the body unit and configured to allow the scattered fines to be transferred to the radioactive waste granulator along a transfer pipe by vacuum pressure.

The invention relates to preventing microplastics from the entering the environment. In particular the invention is directed to regenerating the efficiency of filters for removing microfibers from washing machine waste water, as well as waste from other appliances and other sources of effluent with entrained microplastics. A separator is therefore provided for separating microplastics from waste water comprising a chamber with an inlet and an outlet, at least one sieve structure forming a permeable barrier between the inlet and the outlet and a wash apparatus for washing the sieve structure.

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 filter apparatus includes a filter, such as a cartridge, positioned within a housing. The filter apparatus has multiple ports and valves, so as to allow a user to easily switch between a filtration mode of filtering fluids and a maintenance mode of cleaning the filter. The filter can have a filter substrate in a housing and after filtrate builds up on the substrate, the substrate can be cleaned by directing a spray of fluid, such as from a ring of nozzles at the top of the housing, onto the substrate. A maintenance port can be provided to drain the debris washed from the substrate. The filter can switch between a backwash mode and a filtration mode.

An array of spaced dewatering panels mounted in a spaced relationship in a framework (collectively referred to herein as a “panel support system” or “panel system”) is described wherein the panels are coupled to the framework in a manner that permits them to be pivoted or swiveled between at least a first orientation (or position) and a second orientation (position).

A liquid filtration system comprising a filtration tank with: a separating roof on which are mounted groups of hoses fixed to respective support plates; a fluid distributor plate comprising a central portion without perforations, and a peripheral portion with a plurality of perforations, said distributor plate being located between the hoses and a lower inlet duct for the water to be filtered comprising an upper opening for supplying liquid to the holes near the central portion of the distributor plate and a lower opening for supplying liquid to the holes of the peripheral portion which are furthest from the central portion. The filter comprises a filter material, an outlet duct for the filtered water at the upper area of the tank, a regeneration circuit of the filter medium; a filter self-cleaning circuit and a control panel.

A pre-coating filter device includes: a filtration tank comprising a raw water inlet through which raw water flows on one side, and a drain port at the bottom; a top cover coupled to the upper part of the filtration tank and comprising a coupling hole through the middle part; a purified water discharge pipe coupled to the coupling hole of the top cover; a purified water storage space unit coupled to the lower part of the top cover and located within the filtration tank, and comprising a communication pipe connected to the central part; a filter coupling plate body coupled to the lower part of the purified water storage space unit and comprising a plurality of coupling holes through; and a pre-coating filter coupled to the coupling hole of the filter coupling plate body.

An apparatus and a method for isolating and/or preparing particles are provided.
