6. Description of use of osmosis system
Depending on raw water quality and pre-treatment, the maximum permissible yield is
approx. 60% (RO30G & C: at 15°C ca. 350l/h, at RO60S: ca. 710l/h.). This is a fixed setting
and must not be changed!

Design basis
In practice this means that the permeate output of the osmosis can deviate widely,
depending on the raw water temperature. Water temperatures in Germany generally
range between 8 - 10°C in winter and between 13 -17°C in summer.
Depending on the line arrangement in the building, these figures may also be corrected
upwards.
