You can optimize raw water for catering applications in a targeted way. This filter system ensures balanced mineralization and a consistently high pH value in the filtrate – key factors that minimize 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 food-safe filter systems are pressure-resistant and safe. They can be used worldwide in any drinking water system.
