Non-Chemical Water Treatment for Cooling Towers

Cooling towers dissipate heat through evaporation, using large thermal transfer areas wetted by recirculating water. They often provide the most cost-effective option for removing heat generated in manufacturing, power generation, and large, refrigerant-based air-conditioning systems; but the combination of heat, expansive moist areas, and recirculating water creates an almost ideal petri dish for bacteria and mold. In addition to creating occupant health risks (think Legionnaire’s disease), this biofouling decreases the system’s heat-extracting efficiency by accumulating as a biofilm on surfaces—causing microbe-induced corrosion and providing a substrate for the other bugaboo of the process: scale.
