Water Treatment
Filtration is an effective way of reducing suspended particulates in fluids but is only
one component of a water treatment program. Dissolved solids originally present in
water remaining after evaporation cannot be eliminated by filtration. The
concentration of these dissolved solids increases rapidly and can cause scale and
corrosion. In addition, airborne impurities and biological contaminants, including
Legionella, may be introduced into the re-circulating water through the cooling
equipment being filtered.
To control all potential contaminants a water treatment program must be employed.
In many cases a simple bleed-off in the system may be adequate for control of scale
and corrosion. The filter backwash can be used to constitute a portion of the bleed.
However, biological contamination can be controlled through the use of biocides and
such treatment should be initiated at system start-up and be incorporated into the
total treatment system regime.
For specific recommendations on water treatment contact a competent water
treatment supplier.
