Filter module, especially for filtering water from koi fish pond, is intrinsically stable for supporting several similar modules, has outer wall formed from edge-profiled wall elements

摘要

The module (1) is used to assemble a pond filter from several modules and contains a number of filter compartments (3-6) that pass flow serially, an inlet (7) and an outlet (8). The module is intrinsically stable for supporting several similar modules. The outer wall of the module is formed from a number of edge-profiled wall elements. Independent claims are also included for the following: a filter device for pond water.
