The organic contamination by animals and shoreline vegetation requires thorough and chemical-free water treatment. This is accomplished by four Ospa filter systems ("Model25") connected in parallel, which are characterized by especially high filtration definition. The special internal water distribution, by means of diffusion technology and a filter layer comprised of Ospa filtration quartz sand , provides for a smooth and optimal process without deposits in the filter. Particularly of note are the sturdy filter tanks, which easily withstand the pressure of the majestic waterfall and the relatively high water temperature of 24 °C.
