side stream filter
normally used for industrial cooling tower. Cooling Towers, by design,
flush airborne contamination such as biocides, heat, slime or silt
into the system, where they deposit on heat exchange surfaces.
Suspended matter in the cooling water also supplies living
microorganisms with a constant food source for sustaining life and
Sidestream Filter Benefits
Once a problem has been recognized, several benefits can result from
the use of a sidestream filter. Obviously, not all of those listed
below apply to all systems, and good judgment must be applied before
making any claims. However, bearing that in mind, the following
benefits can be realized:
Since solids are removed from the system, the corrosion inhibitor will
lay down its protective film on clean rather than dirty surfaces,
thereby reducing corrosion rates and increasing equipment life.
When used with good chemical treatment, the filter will keep the
system much cleaner, and, as a result, the need for mechanical
cleaning of exchangers and sumps is reduced.
A cleaner system means better heat-transfer rates for longer periods
In some cases, the removal of suspended solids from the circulating
water allows higher cycle.
Large biological growths and dead organisms are removed with a
sidestream filter. This reduces chlorine demand and makes nonoxidizing
biocides more effective.
