Technical articles on biomass management, molecular diagnostics, and biological wastewater treatment.
Quaternary Ammonium Compounds (QACs) are commonly found in disinfectants, detergents, and personal care products. Their extensive use has led to increased concentrations in wastewater. To better understand how this impacts …
Sep 26, 2025In wastewater treatment, invisible forces shape the performance of entire systems. One of the most powerful—and often overlooked—players in this microbial drama is the polyvalent cation. These positively charged ions, …
Sep 16, 2025Wastewater treatment is a complex process that relies on a delicate balance of physical, chemical, and biological factors. At the heart of most conventional wastewater treatment plants are microorganisms that …
Sep 3, 2025When it comes to nitrogen monitoring in wastewater, ammonia often steals the spotlight. But if you’re only tracking ammonia, you’re missing a critical piece of the puzzle: Total Kjeldahl Nitrogen …
Aug 28, 2025Ever wondered what we’re missing in the microbial world? Just like astronomical dark matter makes up most of our universe but remains largely mysterious, microbial dark matter represents the hidden …
Aug 24, 2025Anaerobic digesters are marvels of sustainable technology, transforming organic waste—like manure, food scraps, and sewage—into renewable energy in the form of biogas while reducing greenhouse gas emissions. At their core, …
Aug 19, 2025Pseudomonas bacteria are proving to be formidable opponents in industrial cooling towers, rapidly developing resistance to glutaraldehyde biocides that were once highly effective. Here’s what’s happening: The Challenge: Pseudomonas species …
Aug 12, 2025As the summer months continue, wastewater treatment plants face a surge in operational hurdles. Higher temperatures not only accelerate biological processes but also exacerbate issues like reduced oxygen levels and …
Aug 6, 2025🧠 When biomass whispers, OUR listens. Oxygen Uptake Rate (OUR) is the microbial pulse check every operator should have in their back pocket. Measured with a simple dissolved oxygen (D.O.) …
Jul 27, 2025The Shannon Diversity Index (H’) is a widely used metric in ecology to quantify the biodiversity of a community. In the context of wastewater treatment, it measures the diversity and …
Jul 22, 2025Mixed Liquor Suspended Solids (MLSS) are the heart of biological wastewater treatment—and how well they settle can make or break plant efficiency. Poor settleability leads to solids carryover, elevated TSS …
Jul 16, 2025Using large air bubbles to mix activated sludge in an anoxic zone while maintaining low redox (oxidation-reduction potential) is a strategy employed in wastewater treatment to achieve denitrification. Here’s a …
