Hydro International installed a complete dewatering system consisting of 3 no. Hydro 400 Double screw presses.

The screw presses were supplied on their own stainless steel structural skids for ease of transport and installation with onboard flocculation tanks. Automatic polymer dosing systems were supplied for use with emulsion polymer, one for each screw press arrangement providing independent redundancy. Transfer augers to collect the dewatered sludge from the screw presses and transfer it to a trailer were also installed as part of the works.

A system control panel manufactured from stainless steel and built to local regulation standards was also provided. Upon delivery Hydro completed local installation works, commissioning and testing.
