Dechlorination Module
(option)
The dechlorination module, which consists of ten 30"-activated car-
bon filter elements, the pre-filtration. Its purpose is to remove pos-
sibly given chlorine from the raw water (catalytic and adsorptive). This
is absolutely necessary for the protection of the succeeding spiral-
wound membrane modules, as these cannot withstand chlorine con-
centrations in excess of 0.1 mg/l. Therefore, the chlorine concentra-
tion in the raw water is to be determined prior to starting operation.
This is carried out by means of the provided UV spectrometer and the
respective chlorine-indicator chemical. For chlorine concentrations in
the raw water that are in excess of 0.05 mg/l, it is absolutely necessary
that the activated carbon filters are installed into the filter bowls.
The measurement of the chlorine concentration of the activated-car-
bon filtrate must be carried out on each day of operation.
The bottom water-sampling valve of the activated-carbon filter can be
used for this. Also, the pressure loss of the active-carbon filter is to be
determined with the two manometers (
Δ
p = upper manometer rea-
ding - bottom manometer reading).
If the chlorine concentration in the filtrate approaches 0.1 mg/l or if the
pressure loss increases above 0.8 bar, the activated-carbon filter ele-
ments are to be exchanged.
