6.1 Technical data BWT bestaqua 6,12,18
Note:
The nominal flow is calculated with following drinking water conditions:
*1)
7ATER¬INLET¬TEMPERATURE¬ª#¬SALINITY¬AS¬.A#L¬MAX¬¬MGL
, Primary pressure inlet 3.5bar and a permeate yield
of 40%. 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.
