Information
he services required to maintain a cooling tower
T
are primarily a function of the quality of the air and
water in the locality of the installation:
AIR:
The most harmful atmospheric conditions are those with
unusual quantities of industrial smoke, chemical fumes,
salt or heavy dust. Such airborne impurities are carried
into the cooling tower and absorbed by the recirculating
water to form a corrosive solution.

WATER:
The most harmful conditions develop as water evaporates
from the cooling tower, leaving behind the dissolved solids
originally contained in the make-up water. These dissolved
solids may be either alkaline or acidic and, as they are
concentrated in the circulating water, can produce scaling
or accelerated corrosion.
The extent of impurities in the air and water determines the
frequency of most maintenance services and also governs
the extent of water treatment which can vary from a simple
continuous bleed and biological control to a sophisticated
treatment system. (See "Water Treatment".)
