Thickening Tank can Further Concentrate the Sludge

lvl. 1 (Lens-Learner)
Further sludge concentration is first achieved by using a Thickening Tank that increases the solids content to between 2% and 5%.
Sludge concentration is achieved by one of two means: flotation and sedimentation to the bottom by gravity or centrifugal force. The concentration operation separates the water from the sludge as much as possible and is cost effective because the costs involved in the process are well offset by the savings obtained by reducing the sludge volume, which reduces the capital and operation of subsequent sludge treatment. cost. In addition to the volume reduction that requires mechanical treatment, sludge concentration is beneficial to the stabilization process (eg, anaerobic digestion process) because it reduces biomass volume, tank size, and heating requirements.
The arch clarifier acclimated aloft is acclimated for primary wastewater treatment. After coursing ample altar and alluvium out of the water, the raw wastewater is beatific to a clarifier. At this stage, the amphibian actual and actual that are calmly precipitated will be removed, consistent in a constant arising that can be added biologically advised in the accessory clearing catchbasin and aftermath carrion acquittal that can be advised or treated.
In the cavalcade abutment thickener, the drive and astriction mechanisms are absorbed to the centermost post. The augment is about accessed through an animated aqueduct accurate by an basin arch arch to the axial tower.
The above column supports the clarifier for secondary wastewater treatment. At this stage, the bacteria consume 90% of the organic matter in the wastewater. After meeting the minimum removal criteria for BOD, total suspended solids (TSS) and pH, the wastewater can be discharged to the environment or further processed.
