Vito's materials research at the basis of demiwater network for the Port of Antwerp


A nearly twenty-kilometre long distribution network has been built to supply the Port of Antwerp with demineralised water. To guarantee water quality, the company Induss asked VITO to identify the most appropriate piping material for the distribution network.

Many chemical and petrochemical companies in the Port of Antwerp depend on demineralised water (demiwater). Large companies often have their own demi installation. Central production would save energy and space. Induss – a Water-link subsidiary – is playing a central role at the Port of Antwerp in producing and distributing demiwater to industry.

“The quality of demiwater is critical”, says Mieke Quaghebeur of VITO. “It contains almost no dissolved substances, and electrical conductivity is minimal. The slightest contamination can render the water unsuitable for industrial cooling and heating processes. Contamination is possible during the transport of demiwater, since leaching can then occur. Hence, the choice of piping material is crucial. Induss asked us to conduct a thorough investigation of different materials to determine the most appropriate material for their water pipes.

Joeri Van Deynze, Project Manager at Induss: “We cannot permit ourselves the slightest loss of quality in the production and distribution of demiwater. Consequently, we were looking for an extremely high-quality material for the piping system.

The collaboration with Induss enables us to reduce our carbon footprint. Transparency in our partnership is also the key for better cost control of water and steam.

We sustainably reduced our demin water cost
Thanks to Induss’ full examination and mapping of my various water needs, I now receive guaranteed quality and secured delivery of industrial water for my production line and that at a fixed price for a full contract length.
