98-04: Fill Fouling Control in Cooling Towers HVAC ApplicationsThe introduction of high efficiency film fill has significantly increased cooling tower performance. However, film fill is more susceptible to fouling than conventional splash fill. This paper discusses two power plants which both have a long history of fouling problems using film fill despite various biocide treatment programs. With the implementation of combined biocide biodispersant treatments, effective fill fouling control is achieved.

Both have been shown to control the tenacious calcium carbonate- silica scale

Power plants that incorporate Air Cooled Steam Condensers (ACC’s) offer significant water savings over power plants using traditional evaporative cooling technologies

In accordance with these codes

Make-up waters with elevated calcium hardness tend to increase the risk of scaling in circulating cooling systems where the concentration of calcium increases through higher Cycles of Concentration (COC)
