Gravity sedimentation process for Treatment of a mixture of sludge in a Sedimentation Tank which comprises a settlement area affected, a transition zone and Compression Zone, which includes the implementation of a number of ultrasonic Energy to the mixture of Sludge In the transition zone

摘要

A gravity sedimentation process for the treatment of a slurry in a thickener to separate a solid from a liquid, the thickener having, at steady-state, a hindered settling zone and a compression zone, the process including the application of an effective amount of ultrasonic energy to the slurry in a transition zone within the hindered settling zone.
