Minimizing salinization, improving your business

At Salttech it is our mission to minimize the impact of salinization globally. Groundwater and rivers are becoming more and more salty. Increasing salinity will not just affect freshwater, plants, and animals but also human lives, our infrastructure, agriculture, and ultimately our drinking water.

We minimize the impact of this salinization by converting brine streams into raw materials. Brine streams contain water, salts, and often valuable minerals. By using our innovative Dyvar® technology to separate those elements, our clients can reuse the produced fresh water and mostly we can help our client to improve and valorize the produced salts as fertilizer or as feedstock for other processes. 

Dutch technology, successfully implemented worldwide 

The Dyvar® technology was originally invented by Mr. Geert Jan Zanstra, a leading process engineer and entrepreneur of large-scale evaporation processes. Working closely with Mr. Zanstra, we were able to enhance his original idea and concept of a combined brine concentration and crystallization technology. An extensive number of industrial applications have been tested. The data this generated allowed us to further optimize the technology. This led to our unique and proven Dyvar® technology in a modular and scalable form.

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.
