Technical articles on biomass management, molecular diagnostics, and biological wastewater treatment.
Ever 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 …
Jul 10, 2025In the bustling microcosm of a wastewater treatment plant, bacteria don’t just float around aimlessly—they evolve, interact, and build structured communities that play critical roles in purification processes. Two major …
Jul 1, 2025As the temperature rises during the summer months, wastewater treatment operators often face a hidden biological battle—Polyphosphate-Accumulating Organisms (PAO) versus Glycogen-Accumulating Organisms (GAO). In Enhanced Biological Phosphorus Removal (EBPR) systems, …
Jun 12, 2025Ammonia oxidation is a cornerstone of the global nitrogen cycle, traditionally attributed to a specialized group of chemoautotrophic bacteria. However, a fascinating and increasingly recognized process called heterotrophic nitrification is …
May 28, 2025In the fight against environmental pollution, scientists and engineers continue to seek innovative ways to degrade toxic compounds that resist traditional biodegradation. Among nature’s unsung heroes, white rot fungi stand …
