Note:
The nominal flow is calculated with following drinking water conditions:
*1)
Water inlet temperature 15°C, salinity as NaCl max. 500 mg/l, Primary pressure inlet 3.5bar and a permeate yield
of 30%. During operation, the actual nominal flow may deviate slightly from the flow indicated in the table due to
fluctuations of the inlet water quality, the flow pressure and the flow continuity.
*2)
For normal operation the manufacturer recommends the inlet of softened feed water with a hardness lower than 14°dH.
