Water Conservation: Reducing Drift and Blowdown in Modern Cooling Tower Design

Water Conservation: Reducing Drift and Blowdown in Modern Cooling Tower Design

Water scarcity and rising utility costs have made Water Conservation a paramount concern for facility operators relying on evaporative Cooling Tower technology. While evaporation is the engine of efficient cooling, minimizing other forms of water loss—specifically drift and excessive blowdown—is essential for a sustainable operation. Our latest cooling tower designs integrate advanced features dedicated to maximizing water efficiency and maintaining the integrity of the water cycle.

Our commitment to water conservation begins with the industry-leading performance of our Drift Eliminators. Manufactured from robust, corrugated materials, these eliminators force the exhaust air through a precise series of changes in direction. This centrifugal action efficiently separates entrained water droplets and returns them to the tower basin. Our designs achieve certified Low-Drift Ratings—often less than 0.0005% of the circulating water flow—dramatically exceeding industry standards and ensuring that water is not wasted and that the surrounding environment is protected from aerosolized particles.

Furthermore, we provide systems that enable higher Cycles of Concentration (COC). COC is the ratio of dissolved solids in the tower water compared to the make-up water. Higher COCs mean less water is discharged via blowdown. We achieve this by offering towers compatible with advanced side-stream filtration and softening systems, which actively remove suspended solids and hardness-causing minerals. This allows the water to remain in the system longer without causing scaling, significantly reducing the amount of fresh make-up water required. Our focus on precision drift elimination and high COC operation makes our Water-Efficient Cooling Towers the definitive choice for environmentally responsible industrial and commercial heat rejection.
