The Drintec ​calcite ​contactor ​technology is ​well accepted ​and proven and ​has a number of ​advantages ​comparted to ​conventional ​calcite ​contactors. ​The key ​advantage is ​that the feed ​of calcite ​cranules to the ​calcite contact ​bed is designed ​to occur ​continuously ​through a ​special set of ​funnels ​delivering the ​granules gently ​to the bed. ​This allows to:

1. Eliminate ​the turbidity ​spikes of the ​product water ​asoicated with ​the intermittent ​reload of ​calcite in ​conventional ​systems;
2. Avoid the need ​to backwash the ​calcite bed ​after a reload ​of media, which ​reduced the ​volume of ​product water ​wasted for ​operational ​purposes;
3. Rreduces the ​total volume (​and assocated ​costs) of the ​calcite bed ​signficanlty ​because the ​continuous load ​of calcite ​allows to ​maintain the ​same depth of ​the calcite bed ​at all times, ​while the ​intermittent ​load (typically ​weekly) of ​conventional ​calcite ​contactors ​requires the ​bed (and ​therefore the ​entire calcite ​structure) to ​be oversized to ​provide ​adequate filter ​bed depth at ​the end of the ​filtration ​cycle before ​bed reloading.

The Drintec ​calcite ​contactors have ​been used at ​the largest ​SWRO plant in ​Europe – the ​200,000 m3/day ​Barcelona plant ​and at a number ​of other large ​and medium size ​facilities ​worldwide and ​has well-proven ​track record.​
