Liquid processing plant for cleaning contaminated liquids by filter element, comprises pressure tanks exhibiting filter element for filtration of raw water to pure water, discharge opening for pure water, and connection

A liquid processing plant (34) for cleaning contaminated liquids by a filter element (10) comprises pressure tanks (36, 38, 40) exhibiting an inlet (44) for raw water, a filter element for the filtration of raw water to pure water, a connection for a pressure pipe (54) over a positive pressure, which is sufficient for pressing down the raw water through the filter element, is generatable in the pressure tank. The filter element is implemented and the positive pressure within the pressure tank is kept at high value in such a manner that the filtration is feasible to a reverse osmosis principle.

The filter element is implemented and the positive pressure within the pressure tank is kept at a high value in such a manner that the filtration is feasible to a reverse osmosis principle. The filtered liquid from the pressure tank is supplied to primary pressure tanks. The pressure tanks are connected with one another over a line that exhibits regulating valves, which facilitates an alternating filling of the primary pressure tank with filtered liquid from the pressure tank. The pressure tank causes a rough filtration and the primary pressure tanks cause a fine to very fine filtration. A purified water tank connects to a discharge opening and exhibits a connection for the pressure pipe with regulating valves. The connection is intended for the filter element to recirculate the liquid. The filter element is designed as an oblong filter element with a pipe that is connected with a hollow filter body which is made of a carrier frame that forms an internally-arranged cavity and is connected with the pipe, a base layer from coarse-grained material, which surrounds the carrier frame and is connected with it, an external layer from fine-grained material, which surrounds the base layer and is connected with it, so that the liquid flow from outside into the filter body and then through the pipe. The filter element exhibits a diaphragm that enables a reverse osmosis filtration. A water processing device is intended to process the filtered-out raw water and exhibits a light s
