Cooling Water Treatment Chemicals

Cooling towers are heat removal devices used to transfer process waste heat to the atmosphere. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or, in the case of closed circuit dry cooling towers. Common applications include cooling the circulating water used in oil refineries, petrochemical and other chemical plants, thermal power stations and HVAC systems for cooling buildings. A successful cooling water treatment must address initial conditioning, scale, fouling and corrosion control. Cooling water treatments can be applied to virtually any cooling system with any type of makeup water. Proper application of water chemistry for a given system, cooling water treatments provide clean heat transfer surfaces that are free of corrosion and scale, and operate at top efficiency. Control of scale and corrosion requires a balanced approach based on a careful appraisal of water quality and operating conditions.
