The primary use of large, industrial cooling towers is to remove the heat absorbed in the circulating water systems in the thermoelectric power, refineries, petrochemical and other industries .
Cooling these plants requires considerable amounts of water; typically 80% of the total consumption of fresh water in coal-based power plants, and 50% of the fresh water consumption in refineries, is used for cooling.
In recent years, due to water scarcity, stricter regulations on disposal and increasing costs of fresh water intake, reuse and/or Zero Liquid Discharge (ZLD) treatments of blowdown water have become critical for these plants, and to the environment.
IDE’s Solutions for Cooling Tower Blowdown Treatment
IDE’s end-to end, integrated cooling tower blowdown water treatment solutions include high-recovery Reverse Osmosis solutions that reduce reject volumes and complete thermal ZLD solutions. These maximize the overall recovery and minimize the volume for disposal.
