Closed-Loop Cooling: Water Saver or Chemical Time Bomb? 

Closed-loop cooling systems, while saving significant water, pose serious chemical management challenges. These systems use additives that can accumulate harmful concentrations, leading to environmental risks when wastewater is discharged. Unplanned drain-downs and valve leaks can exacerbate the issue, prompting regulators to tighten controls. Facilities often lack real-time water quality monitoring, increasing the risk of compliance breaches and environmental damage.
