WATER WITH THE PROTECTION FACTOR FOR CATERING AND VENDING With BWT bestprotect, you can optimise raw water for catering application in a targeted way. This filter system ensures balanced mineralisation and a consistently high pH value in the filtrate – key factors that minimise the risk of corrosion. Hardness-forming calcium ions are practically entirely removed and deposits of limescale and gypsum prevented in the case of raw water containing carbonates or sulphates. Insoluble or difficult-to-remove deposits in machines are now a thing of the past. The filter system consists of a filter cartridge with a BWT besthead filter head (see graphic). Check valves in the filter head prevent water backflow and uncontrolled water discharge. BWT bestprotect foodsafe filter systems are pressure-resistant and
