Read MoreIn the initial stage, gravity drainage occurs on a continuous belt of pockets formed by folding a rectangular piece of filter media.After this initial gravity drainage (thickening) the sludge is transferred to a different belt which passes over another drainage tray before being.
Read MoreThe processes involved in sludge treatment vary from simple gravity thickening to almost complete destruction of solids by incineration.Which process is selected to accomplish the design objectives depends on one or more of the following factors : - character of the sludge; raw, digested, or industrial.- land availability.
Read MoreSereco designs and manufactures gravity thickeners, dynamic thickeners, gravity tables.These equipment can normally be used alternatively and they are included in the process of reduction of the percentage of water in the sludge upstream further treatments such as drying beds, belt presses or centrifuges, drying systems.
Read MoreSedimentation tanks and gravity thickeners use physical settlement mechanisms.Mechanical presses use a combination of pressure and filtration through a cloth attached to a filter plate.Sludge drying beds rely on complex settlement, filtration, and evaporation processes.Planted drying beds use evapotranspiration in addition to the mechanisms.
Read MoreGravity thickening is the most commonly used method for the thickening of primary sludge.It can be carried out in the conventional sedimentation tank (circular tank is preferred).As the sludge gets concentrated by gravity, the supernatant can be returned to the treatment plant (i.E.Primary settling tank).
Read More04-12-2013 thickening or concentration reduction of moisture content of raw sludge.Helps in reducing capacity of digestion tank and provides control of digestion condition.It can produce sludge of less than 10% solid content.Units of thickening are gravity thickener, floatation thickener, elutriation thickener.
Read MoreConsequently, gravity thickening, law pressure dewatering and partial removal of moisture by centrifuge or belt filter thickening, or some other methods of moisture removal from sludge may be related to this term.Even thermal drying may be considered as the process of moisture evaporation from sludge.While in principle these terms are correct, it is better to call all these terms by their real names that .
