6 Tips for Microscopic Evaluation of your Activated Sludge System
EBS believes that monitoring the microbiology (biomass) of your activated sludge system or aerated stabilization basin (ASB) is just as critical as any other test such as pH, nutrients, total suspended solids (TSS), or chemical oxygen demand (COD). Often, the bacteria...
8 Growth Pressures and Their Impact on the Microorganisms in Wastewater Treatment
An EBS microbiologist presented at the Gainey’s Concrete Products Wastewater Conference focusing on the importance of the 8 Growth Pressures and their impact on the microorganisms in wastewater treatment. She also spoke about the value of interpreting laboratory...
Aerobic vs. Anaerobic Treatment in Wastewater Systems: Part 1
A Focus on Aerobic Treatment in Aerated Stabilization Basins (ASBs) There are 2 major types of systems used for wastewater treatment: aerobic and anaerobic systems. Each has different uses along with pros and cons. This particular article focuses on aerobic treatment....
Aerobic vs. Anaerobic Treatment in Wastewater Systems: Part 2
A Focus on Anaerobic Treatment There are 2 major types of systems used for wastewater treatment: aerobic and anaerobic systems. Each has different uses along with pros and cons. This particular article focuses on anaerobic treatment. Aerobic treatment is the focus of...
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...
