Microorganism Control In Water Cooling Systems

emoving heat from building air conditioning units prevents uncomfortable or unsafe heat buildup. Since water absorbs heat efficiently, it serves as the heat transfer medium in most large cooling systems. Usually, the system incorporates some type of water cooling tower to remove heat from the water, al- lowing it to recirculate through the system. In most cases, the water used in these systems is prone to microorganism invasion. To control this problem, cooling system maintenance personnel add antimicrobial pesticides to this water and they may treat the surfaces inside the cooling tower that contact the water. Certain microorganisms that infest cooling tower water have the potential for causing serious health hazards to the public. Others interfere with the efficiency of heat transfer and damage cooling tower components by causing corrosion, clogging, or decay. Some microorganisms produce undesirable odors. R

Closed Recirculating Systems. In closed recirculating systems, the water used for cooling stays contained in closed pipes or tanks. The system uses a heat exchanger to cool the water, which keeps the water from being exposed to the air. This reduces water loss and reduces microbial contamination. For this reason, these systems require
