The 68 MW power station uses a range of fuels including municipal solid waste, commercial and industrial waste and waste wood.

Earlier this year, following a 12-month proving trial, Veolia Water Technologies handed over the make-up water treatment plant to main contractor Hitachi Zosen Inova.

“The plant was delivered on schedule and it has performed outstandingly,” said Philipp Ziegler, head of Energy Systems at Hitachi Zosen Inova.

The bespoke engineered water treatment plant was designed to treat a blend of borehole and towns mains water. It consists of two streams, each capable of producing up to 8m3/h of high purity demineralised water, which can operate as duty/standby.

Each stream has duplex softeners and a MegaRO reverse osmosis unit followed by CEDI-VNX continuous electrodeionisation and final non-regenerable mixed bed polishers charged with nuclear grade resin. A mobile rig allows in situ cleaning of the RO membranes.
