Industrial Cooling Tower Biofilm Monitor

A continuous, non-intrusive sensor system to monitor and quantify the growth of biofilm and scale inside industrial cooling towers.

🎯The Problem

Biofilm and scale buildup drastically reduce cooling efficiency, waste water, and risk Legionella outbreaks, but detection is currently manual/periodic.

💡The Solution

A sensor that uses ultrasound or localized conductivity change to estimate buildup in real-time, alerting facility managers to required chemical dosing or cleaning.

👥Target Users

Industrial Facilities (Data Centers, Power Plants), HVAC Maintenance Companies, EHS Officers
