Abstract

The embodiments herein disclose a method and apparatus for mixing sludge retained in a digester. A jet nozzle assembly for mixing contents of a vessel is used. The jet nozzle assembly having a central outlet pipe terminating at a jet nozzle, a low pressure nozzle assembly disposed concentrically about the central outlet pipe, the low pressure low pressure nozzle having a plurality of openings disposed circumferentially about the low pressure nozzle assembly. The plurality of openings are an axial distance from the outlet jet nozzle.
