How To Clean Scale From a Heat Exchanger


Sep 20, 2017 Leave a comment

Where Does The Scale Come From In A Heat Exchanger? Scale comes in a variety of forms, but the most common is calcium carbonate, or CaCO3. Calcium scale precipitates when the threshold solubility of calcium and carbonate is exceeded. Calcium and alkalinity exist in different concentrations in virtually all make-up sources. As evaporation removes pure […]

Cooling Tower Discharge: The Basics of Bleeding Cooling Towers and EPA – NPDES Regulation


Mar 10, 2017 Leave a comment

What is the Purpose of Bleeding Cooling Towers? The controlled discharge from cooling towers and other recirculating water systems is designed to maintain a certain level of water usage efficiency, or cycles of concentration.  Evaporation causes the concentration of naturally occurring dissolved solids in cooling tower water to be greater than the water source from […]
