The TUNZE RO Ion Exchanger its an additional filter for osmosis units. This additional filter can be fitted to the outgoing water outlet of the RO Station or any other osmosis unit 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 TUNZE 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. 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. 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.
