The DeminWaterPlant Botlek (DWP) of Evides was opened on 5 September 2012 on the Huntsman Holland site. The plant enables Evides to use surface water from the Brielse Meer as a source instead of drinking water to produce demineralised water for industry in the Botlek.
Since 2010, Evides Industriewater has supplied 12 million m3 high-quality demineralised water (demin water) per year to more than fifteen customers in the port of Rotterdam. Demin water is used in the production of high-pressure steam in power plants. The steam can be used as a source of heat in distillation processes in the petrochemical industry. All the elements (ions) that give drinking water its flavour are removed from this water.
