A cleaning module (11, 850) for cleaning sewer pipes (10) including sewer liner, and other types of conduits. The cleaning module (850) may comprise a single hydraulically propelled unit (850), wedge-shaped and selected to fit pipe size. Pipeline walls are scoured by the slurry agitation produced by hydraulic pressure jets (862, 862') in the module (850). The module (11) may comprise a front unit (12) and rear unit (13) or a frame assembly (112) and a drive assembly (113). The modules (11) contain a motor (29, 129). The motor (29, 129) drives flails (34, 134), thereby disintegrating solid waste or generating and propelling a sludge slurry. The slurry scours the pipeline walls by cavitation and abrasion action. A system for cleaning pipelines is described which utilises and recycles, as a solid waste transport medium, nearly one hundred percent of the extracted liquid waste. The mobile extractor and separator unit (600, 900) comprises a separator (940) for separating sludge waste from liquid and particulate waste, and for separating liquid waste from particulate waste. |
