Technical articles on biomass management, molecular diagnostics, and biological wastewater treatment.
In 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. …
Apr 24, 2025Wastewater treatment plants are complex ecosystems with many forms of microscopic life. While bacteria are the primary workhorses, breaking down pollutants, a diverse community of other microorganisms, particularly protozoa, plays …
Apr 21, 2025When running Microbial Community Analysis tests wastewater treatment systems some organisms are seen at very high frequencies. Among them most interesting genera is Paracoccus. We see this organism in municipal, …
Apr 13, 2025Biological wastewater treatment units contain an ecosystem where diverse organisms collaborate to treat the wastewater. These microbial communities play essential roles in removing pollutants, recycling nutrients, and maintaining water quality. …
Apr 7, 2025Biological wastewater relies on multiple microbial communities working together to break down pollutants and recycle nutrients. Among these microbial interactions, syntrophic relationships stand out as a cornerstone of efficient wastewater …
Apr 3, 2025Sulfides are primarily produced through the activity of sulfate-reducing bacteria (SRB). These microorganisms use sulfate as an electron acceptor, generating hydrogen sulfide (H₂S) as a byproduct. While this process is …
