Sludge dewatering specialist Alfa Laval has converted a standard ISO container into a mobile dewatering rig for trial and test purposes.

Equipped with the company’s decanter centrifuge technology, the mobile rig is capable of dewatering 40m3 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 160A 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.

Since the container is completely self-contained, all the sewage treatment works needs to supply is the sludge for treatment, diesel for the generator, potable water for polymer make-up and final effluent for polymer dilution and wash water.

Alfa Laval's operations are based on leading global positions in the three key technologies of heat transfer, separation and fluid handling. Continuous product development is essential to strengthen competitiveness. About 2.7 per cent of total sales are invested annually in research and development, resulting in 25–30 new product launches a year.
