The invention relates to a filter element (1, 31) for use as a particulate filter in a cooling circuit (100), in particular of an electrochemical energy converter, having a conical grid support structure (3, 33). The filter element features at a first axial end a supply opening (23, 49) for supplying a cooling medium to be filtered into the filter element (1, 31) and the grid support structure (3, 33) carries a filter medium (4, 34). The filter element (1, 31) has axially opposite the supply opening (23, 49) a funnel (16, 40) for axially discharging and collecting particulate impurities, and is closed at second axial end. The conical grid support (3, 33) structure tapers from the first axial end to the second axial end. An arrangement of a fuel cell (102) having a a cooling circuit (100) with the filter element is disclosed.

The invention relates to a device for separating solid materials out of liquids or gases and for discharging solid material. The device comprises a pressurised container and at least one filter element, the at least one filter element being arranged in a flexible container which is arranged in the pressurised container and is sealed tightly relative thereto. The pressurised container comprises at least one outlet for discharging the solid material and the flexible container comprises at least one discharge connection, the discharge connection of the flexible container being guided through the outlet of the pressurised container and sealed tightly relative to the pressurised container. In this case the outlet and the discharge connection of the flexible container can be closed and sealed by means of a closure mechanism relative to the environment outside the flexible container and the pressurised container.

Some embodiments are directed to a filter for use with a drain, the filter comprising: at least two external manifolds; and multiple vertical plates that each includes a tube connected to one of the at least two external manifolds, wherein two adjacent vertical plates of the multiple vertical plates are connected to different manifolds of the at least two manifolds, each of the multiple vertical plates also including at least one filter element, each of the at least one filter element including: at least two drains; and a cloth defining compartments configured such that the drain is insertable therein.

A non-powered drain pump screen device is disposed in a river, a stream, a waterway, or a place in which a significant amount soil is carried by a water flow. Upper and lower impellers are provided with upper and lower blades. The lower blades prevent reentry of impurities while rotating due to resistance to a flow of fluid in a non-powered manner. The upper impellers are rotated in a non-powered manner, so that the upper blades filter impurities. The non-powered drain pump screen device is disposed in a waterway to remove impurities at low maintenance costs.

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.

A reactor filter washer dryer (R-FWD) apparatus and methods of using the apparatus for producing washed and dried product of a reaction is disclosed. The R-FWD comprises a vessel defining a process chamber, a filter plate laterally disposed on the vessel base, an agitator assembly, a solids discharge port in the vessel operable to remove the solid fraction of the slurry retained by the filter plate, and a filtrate outlet in the vessel for outflowing the liquid phase of the slurry filtered through the filter plate.

Aspects of the disclosure provide a screw conveyor for discharging solids from a solid/liquid waste stream is provided and comprises a cylindrically shaped screen segment including perforated screen segments and an inlet for receiving a stream including solid and liquid materials, the perforated portions configured to permit liquids and smaller materials to pass therethrough. The conveyor includes a rotor auger disposed within the screen segment and includes helical flights configured to move solid materials larger than perforations on the perforated screen to move vertically when rotated. A drive motor is included to rotate the rotor auger and anti-rotation elements are disposed radially outward between adjacent perforated screen segments and configured to prevent rotation of solid materials to permit the rotor auger to move the solid materials in an axial direction of the rotor auger rotation.
