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 multiplying.
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 of time. 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.
