It relies on the efficient utilization of process wastes by microorganisms in the aeration basin followed by the efficient settling of the activated sludge biomass in the secondary clarifier. Under ideal conditions, this process results in removal or significant reduction of the process wastes and the efficient recycling of biomass back to the aeration basin. </p><p>services offered When problems with wastewater operations are related to these two processes, our laboratory offers microscopic examination of the activated sludge to determine the physical nature of the sludge flocs and the types/abundance of filamentous organisms and their potential role in poor settling or reduced waste utilization. </p><p>Sludge samples are examined using a light microscope with phase contrast capability. Characteristics evaluated include the: </p><p> Physical nature of the sludge flocs </p><p> Presence and distribution of higher life forms </p><p> Abundance and types of filamentous organisms present. </p><p>Microscopic analysis results may show a need for follow-up chemical testing such as nutrient residuals, metals, and organic acids. </p><p>Our laboratory also performs routine characterizations of mixed liquor suspended solids in order to develop baseline data. These data help in diagnosing problems and correcting deviations from normal operations. </p><p>benefits The microbiological characterizations of the activated sludge are useful for determining the probable causes of poor solids separation, foaming, and toxicity. </p><p>This information along with other data gathered from the operation of the waste treatment system gives a more complete picture of the operation of the waste treatment system and clues to improving or rectifying problems with wastewater operations. </p></li></ul>
