In 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 …
Aug 7, 2024Biochemistry of organic acids formation Anaerobic conditions – terminal electron acceptor is an organic compound rather than O2, NOx or SOx. Results in XCOOH (organic acids) & alcohols – this …
Aug 1, 2024Wastewater MLSS or MLVSS is often call the “microbes” or amount of working biomass in a treatment system. However, MLVSS is just the weight of volatile solids in the system …
Jul 30, 2024Nitrite lock occurs when the ammonia (NH₄) doesn’t complete the full nitrification process, which typically involves the following steps: Ammonia Oxidation (NH₄ → NO₂): Ammonia is oxidized to nitrite by …
