Product Description

Suspended solids in cooling tower systems have traditionally been controlled by system
Blow down and use of effective polymer dispersants. Due to the increasing concerns with water use and the desire to reduce wastewater discharges, many cooling towers are now being operated
at higher cycles of concentration than in the past. Operation at higher cycles increases the
problems presented by suspended solids due to reduced blow down and subsequent higher
concentration of suspended solids in the cooling water leading to increased deposition.
 
Suspended solids can be effectively removed from cooling water via side stream filtration, allowing high cycle operation while avoiding deposition problems. While side stream filtration will improve operation of any cooling tower system, its use is mandatory when cooling systems are operated above eight (8) cycles of concentration or in a dusty environment such as Phoenix, Unfortunately, many of the filtration devices currently marketed for this purpose are marginal in their efficacy and, in some cases, may actually degrade overall cooling system performance and increase operating costs due to excessive backwash.

Sand Filters: Suspended solids are removed from water in a sand filter by retention on a porous bed of sand media. The units operate with a combination of surface and depth filtration dependent upon the size(s) of the sand media used and the suspended solids present. They are relatively
popular for cooling water filtration and, in general, do a good job as long as the solids loading is not too high and smaller particles, less than 10 microns in size, are not a major problem. Retained solids are removed from the media bed by backwashing based on either time on line or differential pressure across the bed.
