Product features
BWT Mineral F2/FE is a food grade poly-monophosphate solution concentrate (P content: 1.7%).
The products correspond in composition and purity:
  • the list of treatment substances and disinfection processes according to §11 of the German Drinking Water Ordinance;
  • the Austrian Food Code, Codex Chapter B1 Drinking Water.
BWT Mineralstoff F2/FE builds up a calcium-iron-phosphate protective layer in the water-bearing galvanised steel installation system ("inner pipe sealing") and thus minimises corrosion damage. In addition, the hardness in the water is stabilised and thus limescale deposits are minimised.

The dosing of BWT Mineralstoff F2/FE is carried out without any problems with DVGW/ GS-tested BWT Mineralstoff dosing devices from original containers and is approved according to the Drinking Water Ordinance up to 2.2g P/m³ water. The BWT mineral dosing devices are set accordingly at the factory.
 You can find out how to exchange the mineral substance in our Mineral Substance Video.

BWT minerals are suitable for the treatment of drinking water for human consumption and, in terms of their purity and composition, naturally meet all the requirements of the Austrian Foodstuffs Code (Codex Chapter B1 Drinking Water) as well as the corresponding guidelines of the DVGW.
BWT Mineralstoffe F (3 litres) are designed for use in DVGW-tested BWT Bewados E3 liquid dosing devices. With each water withdrawal in the pipe system, less than 5 mg/l of the BWT mineral substance is added to the drinking water by the mineral substance dosing device.
When added to the drinking water, this reacts on the inner walls of the pipes and thus gradually forms a thin, but firmly adhering, protective layer that separates the water from the pipe (inner pipe sealing). Existing rust/corrosion foci are infiltrated (encapsulated). Regular water tapping at each tapping point is required.
