Pretreatment level (first treatment stage)
In the first treatment stage, the tap water is treated with pretreated water: The feed
water is passed through the pretreatment cartridge by means of a membrane pump.
The pretreatment cartridge contains a combination of activated carbon, catalyst and
downstream reverse osmosis. The pretreatment cartridge removes particles, salts and
impurities, e.g. chlorine, from the tap water.
A large proportion of the impurities are discarded by means of a concentrate outlet
(drainage water outlet).
The treated water is stored in the bag for further use. The quality of the treated
water is monitored via a conductivity measuring cell (LFR).
