Abstract
The study revealed considerable differences in the susceptibility of
the sludge to preliminary treatment by two kind of mixing and
expressed as changes in the initial properties of the sludge and
thus conditions for the occurrence of ultrasonic disintegration in
particular sludge from wastewater treatment plants G, K and Z. The
susceptibility of sludge to ultrasounds which depends on the sludge
properties was explained by the higher COD of dissolved matter after
ultrasonic disintegration of sludge.
