Improving the Performance of Activated Sludge Systems — An Operator’s Perspective
It is generally accepted that aerobic biological treatment systems are robust and stable to the extent that eight key growth pressures are controlled: Organic Loading (BOD or COD) Dissolved Oxygen Temperature pH Nutrients Retention Time Inhibitory or toxic compounds...
Alternative Carbon Source Comparison Case Study
In wastewater treatment plants (WWTPs), bacteria need a constant biochemical oxygen demand (BOD) loading source to sustain their population. Periods of low loading could negatively affect bacteria and lead to a low population, resulting in insufficient biological...
Respirometry, a Valuable Tool
EBS often uses respirometry as a valuable tool when evaluating client wastewater treatment systems and programs. Respirometers are versatile instruments that allow us to assess the treatability of a wastewater sample by measuring the respiration rate of aerobic or...
