Technical articles on biomass management, molecular diagnostics, and biological wastewater treatment.
When you look at activated sludge under the microscope, you usually focused on the big players— metazoa, protozoa, floc size/density, and the filamentous organisms that can make or break settling …
Mar 10, 2026In every activated sludge system, the quality of your solids handling comes down to one thing: how well your biomass sticks together. Operators often focus on filaments, MLSS, or clarifier …
Mar 2, 2026Spring algae blooms are a familiar challenge for many wastewater treatment facilities that operate polishing ponds—also known as maturation, tertiary, or finishing lagoons. These shallow systems follow secondary treatment and …
Feb 17, 2026Filamentous Organism Common Problem(s) Primary Causes / Selectors Notes / Typical Conditions Microthrix parvicella Bulking + Foaming Low temperature (
Feb 10, 2026Wastewater treatment professionals are increasingly leveraging microbial community analysis to optimize plant performance. Among the diverse microbial genera present, Paracoccus stands out for its multifaceted contributions to nitrogen and sulfur …
Jan 29, 2026Deflocculation is one of those operational problems that can turn a perfectly healthy activated sludge system into a cloudy, turbid mess. Instead of forming tight, settleable flocs, biomass disperses into …
Jan 20, 2026For decades, wastewater treatment has relied on the traditional “Bardenpho” approach: Nitrification followed by Denitrification. While reliable, this process is energy-intensive and often requires costly external carbon sources. As we …
Jan 15, 2026We’re breaking down common misconceptions about activated sludge, nitrification, and process control that might be costing you money and stability. As wastewater professionals, we operate at the intersection of rigorous …
Jan 8, 2026Lowering dissolved oxygen (DO) below 2 mg/L in aerobic wastewater treatment can reduce aeration energy costs, but it risks impairing nitrification (ammonia oxidation) and subsequent denitrification (nitrate/nitrite removal), leading to …
Dec 30, 2025Biological wastewater treatment is fundamentally driven by microbial metabolism, where microorganisms transform pollutants into less harmful compounds. The efficiency and sustainability of these processes hinge on the selection and sequence …
Dec 18, 2025Cyanide is one of the most feared contaminants in the industrial world. Known primarily for its extreme toxicity to human and aquatic life, its presence in wastewater presents a significant …
Dec 16, 2025When most people think of a wastewater treatment plant, they picture heavy machinery, massive concrete tanks, and complex piping. But the most important “technology” on-site isn’t made of steel—it’s alive. …
