Assessing the impact of chemicals on activated sludge microorganisms
Abstract
Aerobic biological processes utilize microorganisms, primarily bacteria, but including protozoa, to degrade colloidal or fine particulate matter and dissolved organics, resulting in carbon dioxide, water, and new cell biomass. Such processes produce settleable solids that can be removed in sedimentation tanks. The most commonly used biological treatment process is the activated sludge process. The organisms in this process are key players of effective wastewater treatment. Upon close inspection of the wastewater, a variety of protozoa can be observed having different sizes, shapes, life cycles, and roles in the processes. A procedure has been developed to monitor the toxicity of wastewaters to specific classes of organisms. This procedure will help evaluate and prevent upsets of activated sludge treatment systems.
