Problem:

BOD results, a 5-day lab test, make it challenging for plant operations to adjust treatment processes to adverse levels of BOD real-time.

Plan:

Hach WIMS™ correlation tools automatically generate a site specific equation  to estimate BOD in real-time based  on comparison of Hach UVAS on-line  sensor  (SCADA data) against lab BOD measurements made with the HQ430 Benchtop meter with the IntelliCAL LBOD probe. 

Efficient Management

• 
  UVAS readings can now be used confidently to predict BOD
• The equation generated by Hach WIMS can be imported into a SCADA system for real time monitoring of the estimated BOD
• “Slugs” can now be detected as they come in and can be properly handled
• The plant treatment process is protected from high organic loads
• Compliance excursions due to unexpected organic loads are minimized
