Can drift loss be eliminated? Eradicating Legionnaires' disease from cooling towers.

Summary

Contaminants in cooling tower water will be spread in any droplets escaping the tower enclosure (drift). Large droplets may splash to form smaller particles. Australian legislation requires that drift losses do not exceed 0.02% of circulation. Improved drift eliminators can reduce this to 0.001%. Test methods are described. Further tower improvements are the exclusion of light (so reducing the growth of algae) and filters to prevent ingress of insects, birds, etc., which add to decaying matter inside the tower. Intermittent operation towers can be drained periodically and left to dry out. A.R.T.
