Posted on 5 October 2017

A significant proportion of the plant and equipment has already been installed in the main building, so South West Water presented its flagship project during a trade media event on 31 August.

The plant contains a Six/CeraMac-installation developed by Dutch-based organisation PWN Technologies.

Ion exchange and ceramic membranes
Mayflower Water Treatment Works (WTW) will feature SIX® suspended ion exchange with resin regeneration system, ILCA inline coagulation and CeraMac C90 ceramic membrane microfiltration.

The SIX® suspended ion exchange area is 75 percent complete and the CeraMac installation is expected to be completed by October 2017.

It is the first time that this combined technology will be used in the UK.

High-quality drinking water
Mayflower WTW will replace the outdated treatment works at Crownhill in Plymouth, which was built in the 1950s and is reaching the end of its useful life.

The new WTW will meet the needs of Plymouth’s growing population providing a secure and high-quality drinking water supply for the wider Plymouth area for generations to come.

Second in the world
The project is being delivered by South West Water’s H5O Delivery Alliance, which consists of Arcadis, Pell Frischmann, Balfour Beatty, Interserve and PWNT.

The Six/CeraMac installation at Mayflower will be the world’s second. The first one was commissioned in 2014 at the Dutch water water works of Andijk.

A third Six/CeraMac installation is under construction in Singapore.
