4 Myths About Using Molecular Diagnostics for Wastewater

by Erik Rumbaugh | Oct 23, 2024 | Wastewater Microbiome, Wastewater Monitoring, Wastewater Testing

You may have seen information on using molecular tools or genetic testing in wastewater treatment systems. While 15 years ago, this was either unavailable, expensive, and not useful, things have changed, and Aster Bio’s Microbial Community Analysis (MCA) test gives...

Using qPCR to diagnose the problem after losing nitrification

by Erik Rumbaugh | Oct 15, 2024 | Uncategorized

Nitrification is one of the most complex and crucial processes within the wastewater microbial community. This biochemical process involves the conversion of ammonia (NH₃) into nitrate (NO₃⁻) and is carried out by a specialized group of microorganisms known as...

Using enzymes for improving hydrolysis rate in anaerobic digesters

by Erik Rumbaugh | Sep 19, 2024 | Anaerobic digester

Anaerobic digesters rely on a complex consortium of microorganisms for converting biosolids into methane gas and carbon dioxide. The community includes both bacteria and archaea. The first steps in the process rely on the action of bacteria, while the final steps...
