The Dow fouling-resistant Filmtec reverse osmosis (RO) membrane technology has been used to modify the feedwater source of the DECO water treatment facility in Terneuzen, the Netherlands.

DECO is operated by Evides Industriewater BV and provides the Dow Terneuzen site with process water.

Initially, the DECO water plant feedwater source was river estuary water.

After the re-engineering, the plant was supplied with the effluent from the Terneuzen municipal waste water treatment facility.

Although the organic fouling potential of the feedwater significantly increased, the retrofit was achieved through the replacement of the existing membrane modules with the latest high-performance fouling-resistant brackish water membranes from Dow.

Additionally, the feed pumps were changed and slight modifications were made for piping.

The benefit of this retrofit is double: water recovery increased by 20 per cent and the operational costs diminished by 50 per cent, due to the lower feed pressure requirement.

In addition, the city’s waste water is no longer discharged to the sea, but given another life as process water.

‘Since the start-up in March 2007, these robust membranes have shown that they can virtually withstand the necessary harsh and frequent cleaning without compromising a stable performance,’ said Kevin Reyntjens, European technical service and development leader for Dow Water Solutions.
