EBS believes that monitoring the microbiology (biomass) of your activated sludge system or aerated stabilization basin (ASB) is just as critical as any other test such as pH, nutrients, total suspended solids (TSS), or chemical oxygen demand (COD). Often, the bacteria...

It is generally accepted that aerobic biological treatment systems are robust and stable to the extent that eight key growth pressures are controlled: Organic Loading (BOD or COD) Dissolved Oxygen Temperature pH Nutrients Retention Time Inhibitory or toxic compounds...

MLSS testing measures the total concentration of mixed liquor suspended (non-soluble) solids in the aeration basin of an activated sludge system. The mixed liquor suspended solids (MLSS) data is critical in determining the operational behavior and solids inventory. It...

Filamentous bulking has long been the bane of activated sludge operations. Biomass or sludge bulking is generally defined as mixed liquor with a Settled Volume Index (SVI) of >150 ml/g. However, sludge bulking does not definitively translate to a sludge bulking...
