The WaMax milling system from IBG HydroTech is used for the removal of roots, mineral de­posits, concrete, protruding sockets and other rehabilitation prep work. The pressure- and volume-independent control-milling system with small revolutions of approximately 250 rpm delivers effective performance. It works in pipe diameters from 3 to 40 inches. The system can be equipped with liner and rupturing knives, a round saw blade for removing roots and a pipe socket cutter. The system can be driven by process water from the water treatment system as well as recycled water without problems. It can also be used for oval and egg-shaped profiles. www.ibg-hydro-tech.de/en.
