Dailuaine Sludge Dewatering with ROTAMAT® Screw Press RoS 3Q

19.08.2014
When Clearfleau built their REA (British Renewable Energy Association) award winning Anaerobic Digestion plant for Diageo at Dailuaine they chose the HUBER ROTAMAT® RoS 3Q Screw Press for dewatering the CAF unit sludge’s. Having used these Screw Press’s on 2 previous projects they were fully aware of the quality of the HUBER equipment and engineers to meet the required performance.

Clearfleau take the 1000 M³ per day of liquid waste streams from the malt whisky Distillery and convert this waste to a useable renewable energy in the form of heat and power for reuse within the Distillery.

Having converted the bio-energy solids to energy the digestate is treated in a CAF unit and the solids are recovered as sludge at around 4% dry solids. This is treated by a HUBER Screw Press to provide a dry cake for trailer disposal for the local farmers to use as a valuable nutrient rich fertiliser. Environmentally it’s a win-win all round with waste converted to power, heat and fertiliser, and savings made financially and ecologically.

HUBER supplied the sludge handling, chemical preparation and dosing, and discharge conveyor and associated controls and instrumentation for this project.

The Control panel was designed and built by HUBER UK to ensure the clients requirements regarding control was met.

The cake is easily stored, spreadable and the nutrients embedded provide valuable fertiliser reducing the need for expensive chemical fertilisers.
