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
