Stores the pure water that is produced.
Prevents the entry of particles > 5µm
and guards against too high free chlorine concentrations.
Binds calcium and so prevents precipitation of it.
Semi-permeable thin-film composite spiral wound membrane.
Prevents the entry of bacteria and particles > 0.2 µm with
drawn-in air.
Detects the filling level in the storage tank.
Increases the inlet pressure to the required working pressure.
Pumps water through the pressure switch to the user.
Switches the pressure pump off when no water is being
drawn from the tank.
Measuring device for determination of the conductivity as a
parameter that indicates the raw water quality.
Measuring device for determination of the conductivity (after
RO) as a parameter that indicates the pure water quality
Reduces the bacterial content in the water and serves to pre-
vent bacterial growth and biofilm formation on the inside sur-
faces of the storage tank.
Is closed during stand-by and during standstills. It prevents
water flowing into the system when the system is not in oper-
ation.
Serves to adjust the working pressure and the WCF rate.
Opens for the cleaning of the membrane, before pure water
production, after pure water production and at least every 12
hours.
Prevents running dry of the measuring cell (QIA301).
For withdrawal of pure water from the storage tank (B1).
Prevents the entry of bacteria and germs.
Prevents water backflow into the tank.
