Optimizing blowdown frequency is crucial to minimize water waste in HVAC cooling towers. Facility managers can achieve this by implementing a blowdown control system that monitors conductivity, pH, and other water quality parameters. This system can automatically adjust blowdown frequency based on the tower’s operating conditions, ensuring that only the necessary amount of water is discharged. Additionally, implementing a side-stream filtration system can help reduce blowdown frequency by removing contaminants and suspended solids from the tower water.
