Technical articles on biomass management, molecular diagnostics, and biological wastewater treatment.
As 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 …
May 21, 2025Managing manure in livestock operations is a complex challenge, with problems related to polluted water, odors, and decreased livestock health in enclosed areas. By introducing beneficial biological agents, producers can …
May 8, 2025Microbial communities play a crucial role in wastewater treatment, helping break down organic pollutants, remove nutrients, and support overall ecosystem health. When analyzing these environmental cultures, researchers use molecular tools …
May 7, 2025Bioaugmentation tools have been around for over 50 years in wastewater treatment. While they have been used successfully in numerous locations, there have also been numerous applications with limited results. …
