UK SW Water ContractsPWN Technologies to Design Its New Water Treatment Works in Plymouth, Using in Exchange and Ceramic Microfiltration Technology
UK utility South West Water has commissioned Dutch company PWN Technologies to design its new water treatment works in Plymouth, using ion exchange and ceramic microfiltration technology.
The proposed 90,000 m3/day plant will replace the existing Crownhill Water Treatment Works and will treat reservoir and river water, which has a high content of humic substances.
A combination of Ion eXchange (SIX®) and ceramic microfiltration (CeraMac®) technology will form the core of the new treatment train, which will also consist of granular activated carbon and ultraviolet treatment technology. Produced water will be integrated into the existing drinking water infrastructure.
In April 2013 the utility started a trial using the technology to treat 140 m3/day of surface water to confirm feasibility and to establish operating and design criteria.
Although this was first trial of its kind in the UK and Europe, elsewhere in Singapore the technology has been demonstrated before.
The S$5million (US$3.9 million) ceramic membrane demonstration plant was built at Singapore's national water agency PUB's Choa Chu Kang waterworks. The 1200 m3/day plant is using ceramic membranes supplied by Japanese company, Metawater.
