  • Sludge Thickening an overview ScienceDirect Topics

    The sludge concentration achieved in the thickener is independent of the feed concentration. However, the greater the feed volume, the larger the thickener will be. There are several thickener designs in use; most are of the settlement type developed for industrial applications, which uses heavy duty scrapers with a picket-fence attachment.

  • Sludge Thickening an overview ScienceDirect Topics

    The primary objective of sludge thickening is to concentrate the solids, thus reducing the volume of sludge. Thickeners may increase the solids concentration by a factor of 2 to 5 and produce a clarified liquid effluent. Thickening is accomplished by either gravity or dissolved-air flotation.

    2018-3-6 · Sludge flows into the thickening tank, and eventually, it removes excess water from the solids collecting at the bottom. A gravity thickener has a similar process to the tanks, but it has a sloped design so that solids collect at the base. Dissolved-air flotation is another type of sludge-thickening
