Sludge gravity thickener
WebbAfter the sludge has been flocculated in the feed pipe, it enters the gravity zone where most of the liquids and solids are separated. A spreader plate ensures uniform distribution over the working width of the belt. PowerDrain belt thickener units can be equipped with two to four rows of ploughs, which compact, rearrange, and deflect the sludge. WebbTerex deep cone thickeners are designed and constructed to give optimum performance and reliability in even the toughest applications. The deep cone provides a smaller footprint than a rake style thickener saving space on site. The thickened sludge underflow can reach solids content of over 50%. With no moving parts there is minimal servicing ...

WebbThickening is defined as removal of water from sludge to achieve a reduction in moisture content of slurries. The resulting material is still fluid. Thickening is used at most wastewater treatment plants, as an economic measure, to reduce the volume of sludge or for greater efficiency in subsequent processes. WebbGravity thickeners typically consist of a circular tank with a side water depth of 10 to 13 feet. Gravity thickener tank diameters range significantly. Floor slopes of 2:12 to a 3:12 are typical. (WEF MOP 8, 1992) Operational Controls A number of items should be considered in the design and operation of a gravity thickening system. They include:
