摘要

The filter system unit for removing particulate and/or dissolved components from especially stagnant waters has feed lines (2,3) and return lines (26,29) guided into or from the installation space of the filter system unit through gastight and watertight wall bushings (1,1a). The feed lines are connected tangentially and vertically to a prefilter (4). A funnel-like sieve (7) is constructed with an inclined angle of preferably 45 degrees, and at the lower end of the sieve a pipe transition to preferably DN40 is incorporated.
