Water Towers - Silt, Sediment, Or Slime In The Tower Basin


Running your hand along the tower basin should not pick up very much sediment or slime. Sediment implies either that the tower is not being blown down adequately (which could result in scale buildup in the chiller condenser), or inadequate water filtration. Slime implies the cooling tower water chemistry is out of balance which will quickly foul chiller condensers. The basin water should be clear and essentially colorless. An excellent way to check for potential condenser fouling is to compare the chiller's leaving condenser water temperature with the temperature at which refrigerant is condensing (you can do this using condenser pressure and a refrigerant properties table). While this can be tedious for the uninitiated, it's almost always feasible to do this in the field with simple instrumentation. Comparing this information with equipment data from the manufacturer often pinpoints the problems.
