BEWAMAT COMB / PRO

The BWT well water specialists

You live too far away from a municipal pipeline or you prefer your own borehole supply? Then, better check twice your water quality and consider a water treatment process with our latest innovations BEWAMAT COMB/PRO. The ideal solution for requirements of an independent water supply – e.g., an isolated farm, a winery or private holiday home.

Every homeowner knows the common problems with well water – mostly brown/orange stains due to high loads of iron and/or black scale because of manganese. The new multi-target filters are dealing with hardest conditions of well water. Patented unique Ecomix® filter material has been developed to safely remove:

• IRON Reduces iron concentrations: (<10 ppm) dissolved, oxidised, organic and colloidal.
• MANGANESE Reduces manganese concentration (< 3 ppm)
• ORGANIC MATTER - BAD SMELL AND TASTE Effectively reduces colour, tannins, and chemical oxygen demand. Maximum allowed influent COD is 20 mg O2 /l (80 ppm KMnO4).
• AMMONIUM Reduces concentration of ammonium (<2 ppm).
• HARDNESS Softens water with hardness of up to 30°dH (535 ppm CaCO3 ).

BEWAMAT COMB / PRO

The multi-target filter cleans drinking water by lowering the concentration of iron, manganese, ammonium and other organic substances and reducing water hardness. During filter operation, the water flows from top to bottom through the filter bed. When the filter medium is used up, the multi-target filter automatically starts regeneration.
