Commercial Cooling Tower Daily Water Treatment Conductivity Log
Daily log for monitoring conductivity, pH, temperature, and inhibitor residual in commercial cooling tower systems. Ensures water chemistry stays within manufacturer specifications to prevent scaling, corrosion, and biological fouling.
This log provides a standardized daily record of key water chemistry parameters for commercial cooling tower systems. Conductivity, pH, temperature, and inhibitor residual are measured and compared against established thresholds to prevent scale formation, corrosion, and microbiological growth. Consistent data collection supports proactive treatment adjustments and regulatory compliance with local discharge permits. Any reading outside the acceptable range triggers a documented corrective action to protect equipment lifespan and system efficiency.
- Lockout/Tagout: Isolate cooling tower fan and recirculation pump before accessing water sump for manual sampling. Verify zero energy state.
- Chemical Handling: Wear approved gloves, safety glasses, and face shield when handling corrosion inhibitor and biocide chemicals. Review SDS before use.
- Personal Protective Equipment: Hard hat, safety boots, high-visibility vest required in cooling tower vicinity. Hearing protection if fan is operational during sampling.
- Meter Calibration: Conductivity meter and pH meter must be calibrated per manufacturer instructions within the last 24 hours. Document calibration on the back of this log.
