we have shown numerous customers that we are a reliable partner

fast, efficient and various filtration techniques

specialized in off-spec treatment

With our mobile filter installations, we offer efficient solutions for the handling of off-spec, ship - and industrial cargoes in all European ports and terminals. We use the suited filtration techniques to remove various contaminations.
For example, you can count on us to remove solids (rust particles, sediments, etc.) or liquids such as water (dehydration), or to deodorize and decolorize liquids.

In our research center in Antwerp, our R&D chemists analyze the most optimal treatment with practice-based laboratory tests. Moreover, as experts in the field, we can offer end-to-end solutions and services.
