Sludge dewatering specialists, Alfa Laval, have recently converted a standard ISO container into a mobile dewatering rig for trial and test purposes.

Equipped with the latest Alfa Laval decanter centrifuge technology, the mobile rig is capable of dewatering 40 cubic metres of sewage sludge per hour. It comes equipped with its own diesel-powered generator and an integral liquid polymer make-up system. It can also be adapted to work with powder polymer for short periods for test purposes and can also be wired into a 160 amps mains supply, if required, for a longer period. An on-board, retractable screw conveyor transports the dried sludge into a feed hopper or main conveyor system.
