COOLING TOWER

CROSSFLOW PATTERNS

-
Advantages:
-
-
Typically lower initial and long-term cost, mostly due to pump requirements
-
-
MAINTENANCE
Periodic inspection of mechanical equipment, fill, and both hot water and cold water basins to ensure that they are maintained in a good state of repair.
Periodic draining and cleaning of wetted surfaces and areas of alternate wetting and drying to prevent the accumulation of dirt, scale, or biological organisms, such as algae and slime, in which bacteria may develop.
Proper treatment of circulating water for biological control and corrosion, in accordance with accepted industry practice.
Systematic documentation of operating and maintenance functions. This is extremely important because without it, no policing can be done to determine whether an individual has actually adhered to a maintenance policy.
WATER PROBLEMS

SCALING
Hot water dissolves solids faster than cold water. By the time the hot water returns to the tower, it is full of suspended solids. When hot water enters the cooling tower laced with suspended solids, it undergoes evaporation. This process removes water and leaves the solids. In addition, suspended solids can accumulate in the water and form deposits (scale).
