This additional filter can be fitted to the outgoing water outlet of the RO Station as a water hardener or silicate filter. The tank contains two screw caps with plug-type connectors for the hose of the osmosis plant and two brackets for a direct attachment on the RO Station. In particular, we recommend the use as silicate filter at the out-going water outlet in order to remove the silicic acid. Thus, the growth of diatoms and mucous algae can be avoided in the aquarium. A mixed-bed ion exchanger with colour change is used as a medium (article No. 8550.501).
In order to increase the calcium content of the out-going RO water, the mixed-bed ion exchanger granulate can be replaced by the calcium carbonate granulate (article No. 880.901). The out-going RO water takes up high quantities of calcium hydrogen carbonate. In the process, the hardness of the out-going RO water is increased, i.e. the carbonate hardness is increased.
