Comparing Performance of DO Probes Used to Monitor Aeration Basins
Edward Askew, Ph.D. of Askew Scientific Consulting, LLC compared the performance of DO Probes at two wastewater treatment plants. A white paper presents Dr. Askew's findings, which demonstrate that when DO probes and controllers are connected to blower controls through a SCADA system, the WWTP will be able to:
- Optimize sewage treatment
- Reduce energy bills
- Comply with National Pollution Discharge Elimination System permit requirements
EPA Approves In-Situ RDO Methods
The U.S. Environmental Protection Agency (EPA) has granted nationwide approval to three optical RDO® dissolved oxygen methods. For details, read the press release.
These methods can be used in the measurement of Biochemical Oxygen Demand (BOD), Carbonaceous Biochemical Oxygen Demand (CBOD), and Dissolved Oxygen (DO) under the Clean Water Act. NPDES permit holders can use RDO methods for process, field, and laboratory applications.
For more information on the final Methods Update Rule published on May 18, 2012, visit EPA Regulatory Changes.
