Mixed 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 in effluent, and headaches for operators. Fortunately, there...

Using 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 breakdown of why this approach is effective:...

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 forms of bacterial aggregation dominate: flocs...

As 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,...
