Technical articles on biomass management, molecular diagnostics, and biological wastewater treatment.
You have probably read about probiotics (bioaugmentation) and prebiotics being used in wastewater treatment, postbiotics are another less talked about potential tool available for optimizing your biomass performance. Postbiotics application …
Dec 10, 2024For aerobic wastewater treatment systems, maintaining Dissolved Oxygen levels is key to efficient treatment. Operating a combination of blowers or surface aerators represents a significant use of energy/utility costs. Picking …
Dec 6, 2024Simultaneous Nitrification-Denitrification (SNdN) is an advanced process used in wastewater treatment to remove nitrogen compounds. Here’s a detailed look at how it works: Process Overview: Nitrification: This involves the biological …
Nov 21, 2024Wastewater bacteria growing in long chains of cells with high surface area are termed filamentous organisms. When you mention filamentous bacteria to most operators, the discussion usually focuses on the …
Nov 5, 2024Phosphate Accumulating Organisms (PAO) and Glycogen Accumulating Organisms (GAO) are two types of bacteria that play crucial roles in the enhanced biological phosphorus removal (EBPR) process in wastewater treatment. PAOs …
Oct 31, 2024Bioremediation application summaries are usually done on soils with high levels of contaminants and with highly biodegradable compounds such as fuels or crude oils. Aster Bio has been working on …
Oct 23, 2024You 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 …
Oct 15, 2024Nitrification 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 …
Oct 4, 2024In wastewater treatment and environmental monitoring, molecular testing technologies have revolutionized the way we analyze microbial populations and identify specific contaminants. But what’s the difference? qPCR vs MCA Tests… Among …
Sep 19, 2024Anaerobic 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 …
Aug 28, 2024When discussing wastewater system organisms, we clump organisms into functional groups based on their ecological impact(s) in wastewater treatment. After working with Microbial Community Analysis (MCA) testing for over 8 …
Aug 19, 2024Rapid temperature changes tend to cause more problems than gradual drift in WW. Even with slow increase in temperatures, you reach inflection points where system drifts above the growth range …
