Handle complex brines more efficiently, improving your business
At Salttech, our mission is to reduce the global impact of salinization.
We address this challenge by turning brine streams into valuable resources. Brines often contain water, salts, and minerals. With our Dyvar® technology, we separate these elements so that clients can reuse the recovered water, comply with environmental regulations, reduce disposal costs, concentrate feedstock brines and semi-finished products or condition chemical mother liquors. In doing so, we help protect natural resources while improving operational and economic performance.

Dutch technology, successfully implemented worldwide
Dyvar® technology was originally developed by Mr. Geert Jan Zanstra, a renowned process engineer and entrepreneur in large-scale evaporation systems. In close collaboration with Mr. Zanstra, we further developed his concept of a combined brine concentration and crystallization process into a robust and scalable solution. An extensive range of industrial applications have been developed. The data gathered from these cases enabled us to refine and optimize the technology even further. This resulted in the proven Dyvar® system as we know it today.
Our technology treats brine in a manner it has not been treated before. It goes beyond traditional technologies. Nowadays, Dyvar® technology is applied in different market segments and various industries where other technologies haven’t succeeded. Our specialized team is eager to learn how we can also deploy our Dyvar® technology in markets where our technology is still allowed to do its magic.
