Technologies

More than 40 technologies that we combine according to the source water or effluent and the quality needed.

Our team brings deep experience from more than 300 projects delivered, most of them turnkey and tailor-made, across a wide range of industries. Knowing the technologies well, and selecting and combining them efficiently with the smallest footprint, capital cost (CAPEX) and operating cost (OPEX), is crucial and sets us apart. Having the best simulation tools and the experience to get the most out of them is what makes our clients succeed.

We also make our technologies, processes, tools and business model available to other water treatment companies, to support them wherever they need it, with the strong competitiveness we have in containerization, integration and international logistics.

Containerized plants

We offer the option of containerizing the plants, building them inside standard shipping containers (10, 20 and 40 ft, standard and High Cube). They travel by road or sea and are installed in far less time than a conventional plant.

For any country
The container ships with the plant assembled, hydraulically and electrically tested in the workshop (FAT) and ready to connect.
Less civil work
Compacted, level ground and the connections are enough. Civil works only where seismic or wind design calls for them.
Scalable and mobile
Add modules, or move it when needs change.
Temporary or emergency
A temporary treatment plant while the permanent one is built, after a breakdown or in an emergency.
