Thickening for Municipal Wastewater Treatment

Web[Review the factors of gravity thickener operation in the workbook.] Gravity thickeners are better suited for primary sludges, or sludges from a primary clarifier, than secondary sludges, or sludges from secondary clarifiers. Secondary sludges typically contain bound water which can cause the sludge to not settle since it is less less dense. WebThickening is usually accomplished in a tank called a gravity thickener. A thickener can reduce the total volume of sludge to less than half the original volume. An alternative to gravity thickening is dissolved-air flotation. In this method, air bubbles carry the solids to the surface, where a layer of thickened sludge forms. Digestion my little streamWebThe Gravity Belt Thickener is used to thicken sludge prior to centrifuge or digestion processes.
