Cooling Water Pretreatment
Water pulled from cooling towers to remove mineral build-up is called “blowdown” water. Cooling towers rely on water evaporation to create the cooling effect. As water evaporates, the mineral concentration content (calcium carbonate, magnesium, sodium, salts) of the remaining water increases. These minerals cause scaling on equipment surfaces that can damage the system. The blow-down water can be discharged to wastewater or, in some cases, this water can be reused.
