A. Bacterial Contamination
Bacterial contamination of recirculated water in the cooling tower is possible.
It is therefore recommended that, after the coolingtower is commissioned, a regular maintenance program be investigated.This should included treatment of the recirculated water.
As we are not experts in this field, we strongly recommend that a reputable water treatment company be consulted for the treatment of the system's recirculated water.
B. Water Quality Control
Poor quality of recirculated water due to air pollution, corrosion, scale and algae growth will impede the performance of water cooling equipment.We recommend a periodic water analysis and that blow-down be initiated to maintain the water quality within the water cooling system to the following criteria:
