A cooling tower water treatment system is an arrangement of technologies that remove damaging impurities from your cooling tower feed water, circulation water, and/or blowdown.

Project Background A natural gas-fired combined cycle power generation facility located in Idaho contacted QUA to find a solution to improve the performance of a water treatment system used to recycle the plant’s cooling tower blow down water. This water treatment system is an essential aspect o Cooling towers cool water through an evaporative process (described below). Cooling tower operation can be one of the largest water and energy consuming activities for many manufacturers. Often the towers are managed by third party service providers. This fact sheet provides a basic description of cooling towers to

The thermal efficiency and longevity of the cooling tower and equipment depend on the proper management of recirculated water. Water leaves a cooling tower system in one of four ways. Evaporation: The primary function of the tower and the method that transfers heat from the cooling tower system to the environment. Reuse of Treated Water in Cooling Towers The main purpose of the cooling tower is to expel the heat from the heated water efficiently. Heat is transferred to air through evaporation. balance, fresh make-up water is added and concentrated blowdown water is discharged.

Blowdown Control Maintaining boilers at their conductivity setpoints eliminates wide control swings that can increase blowdown unnecessarily. Cooling Tower Using soft water or improved inhibition chemistries can reduce blowdown. Rinse Waters Rinse waters may be cascaded from one rinse bath to another to reduce water usage and wastewater generation.
