As cooling water cycles in concentration, the aqueous environment becomes more corrosive due to elevated conductivity, chlorides and sulfates. Check Pages 1-16 of NA Light - Cooling Water Brochure 2016 in the flip PDF version. These extra areas of the cooling tower system contain stagnant water, which can cause building up of bacteria and sludge in recirculating system, and can then contaminate the system. When we use water to lower the operating temperature of equipment or entire plants, it is called cooling water . On a monthly basis, one needs to inspect the general conditions of the cooling tower and the clarity of sump water. Passivationthe formation of a corrosion-resistant oxide on a clean metal surfaceis the key to optimizing system reliability on the waterside of heat exchangers. Adiabatic cooling systems function similarly to dry cooling systems, but with the incorporation of pre-cooling pads; running water over pre-cooling pads and drawing air through the pads depresses the ambient dry bulb of the incoming air. Nalco Water Helped a Cargill Food Processing Plant Reduce and Recycle Wastewater; Waiting to start the passivation, for even a week after water circulation has been started, will likely result in an incomplete passivation, white rust and eventual leaks. Hardcover. Nalco Water is uniquely qualified to help you manage and reduce Legionella risk as the global leader in water safety for over 30 years. As regulations limit the use of many corrosion inhibitors for the hot dip galvanizing process, such as chromates, the passivation process for protection has become even more critical. "Water is a nontoxic and safe resource that has excellent heat transfer properties, making it an ideal medium for cooling applications," said Vishal Sharma, senior vice president and general manager, Nalco Water Asia Pacific, Ecolab.
