The joint project “HaSiMem – Water recovery from tailings heap leachate based on membrane distillation processes and combination with crystallization”, funded by the German Federal Ministry of Education and Research, is led by K -UTEC AG Salt Technologies and will be implemented over the next few years. three years with partners Fraunhofer Institute for Ceramic Technologies and Systems IKTS, Solarspring GmbH and application partners K+S AG and LMBV mbH. Using the example of saline water from potash industry tailings heaps, it will be investigated whether the membrane distillation process offers advantages in water treatment over conventional evaporation at scale. industrial.

“Thanks to great efforts and significant investments, we have already done a lot to reduce the environmental impact of salt water,” explains Dr. Martin Eichholtz, who leads the project at K+S. At the K+S Werra plant, for example, the volume of salt water has already been reduced by 60% since 2000. and Weser – technological innovations can also contribute to this, whereby the salt water from the potash tailings heaps can be processed more efficiently and at the same time more environmentally friendly,” says Eichholtz.

In addition to the goal of further reducing the environmental impact of mining, K+S also pursues a clear climate strategy. “So we are excited to work with our partners to advance a new process for treating saline water,” concludes Eichholtz.
