A filter for removing particles held in suspension by a fluid. The filter includes (a) a manifold having an inlet and an outlet; and (b) a main filter body connected to the manifold. The main filter body includes a flow disrupter, the flow disrupter comprising a tiered plate assembly arranged in the filter body and each plate in the tiered plate assembly comprises an arrangement of apertures. The inlet of the manifold, the tiered plate assembly, the outlet of the manifold and a bottom of the main filter body define a flow path for fluid to be treated.

A method of treating cooling circuit water of industrial plants (2) contaminated with organic substances and inorganic particles, comprises the following steps: a) separating the organic substances and inorganic particles from the cooling circuit water to obtain precleaned cooling circuit water; b) cooling the precleaned cooling circuit water by an open cooling tower (11) to obtain cooled precleaned cooling circuit water; c) desalinating at least a partial volume flow of the cooled precleaned cooling circuit water by an desalination plant (14) to obtain cleaned cooling circuit water; and d) adding bacteria capable of degrading organic substances present in the cooling circuit water. The bacteria are added to the cooling circuit water before the separation in accordance with step a), before the cooling in accordance with step b) and/or before the desalination in accordance with step c), to form a biological cleaning stage.

In order to make available water that is as germ-free as possible, the invention provides a water installation system (1) comprising an extraction point (38) and/or an outlet, wherein the water installation system has a direction of flow (D) towards the extraction point and/or towards the outlet, and comprises at least one chemical germ barrier (200) upstream of the extraction point and/or the outlet when viewed in the direction of flow, wherein the chemical germ barrier is selected in particular from the group consisting of at least one alkalinizing and/or oxidative material, silver, chlorine, and combinations thereof.
