Abstract

A method for operating and improving the throughput and efficiency of a worm centrifuge by introducing, at a controlled frequency, successive pressure surges into the concentrated sludge fraction within the bowl separator preceding the solids discharge opening whereby the pulse frequency and the level of pressure are controllable and can be controlled as a function of the sludge fraction throughput through the separator.
