EWS makes a suction Machine Mounted on a suitable trailer chassis, which can be towed to the work area by a suitable agricultural tractor. The high-performance exhauster/compressor can be operated in both vacuum and pressure modes. Blowing of pressurized air/water into the chamber dislodges the sediment solids which combine with the liquid effluent to form sludge. This is then collected into the tank by operating the system in vacuum mode.
