Veolia Water Technologies were contracted to design a demineralisation plant for a new power station at Ferrybridge, West Yorkshire. The plant is to treat a blend of borehole and town mains water to produce make-up water for the power plant's high-pressure boilers.
Multifuel Energy Ltd operates the new £300m power station, which generates 68MW of low carbon electricity using a range of fuels, including municipal solid waste, commercial and industrial waste and waste wood.
Following a 12-month proving trial, the bespoke engineered water treatment plant was handed over to main contractor Hitachi Zosen Inova.
The plant consists of two streams which can operate as duty/standby. Each stream is capable of producing up to 8m3/h of high-purity demineralised water.
The streams include:
The plant is skid-mounted to the highest possible degree and factory tested to reduce site installation time. The mobile rig allows in-situ cleaning of the MegaRO™ reverse osmosis membranes.
A motor control centre using a Siemens S7-300 programmable logic controller runs the water treatment plant. The controller interfaces with the site DCS via a Profibus DP communication link.
Veolia’s bespoke engineered water treatment plant can produce up to 8m3/h of high-purity demineralised water that meets the boiler make-up water specification:
Hitachi Zosen Inova Head of Energy Systems, Philipp Ziegler, was pleased with the result. “The plant was delivered on schedule” he said, “And it has performed outstandingly.”
