Selection first and foremost must consider the fouling tendencies of the water.
Cooling towers play an essential role at many chemical plants. As with any other heat exchanger, maximizing efficiency from the standpoint of both equipment design and protection from fouling, scaling and corrosion is crucial. With cooling towers, fill selection is a critical aspect in this regard. At first glance, high efficiency film fill may seem the most desirable option. However, if poor water quality causes this fill to rapidly foul and plug, it may incur excessive maintenance costs. So, here, we’ll examine the fundamentals of fill types and also look at important chemistry issues that influence selection. Proper makeup-water pretreatment may enable selecting a higher efficiency fill than otherwise possible.
