Project for the treatment of saline mining wastewater launched / 2022
HaSiMem – Water and salt from saline water

The availability of water of suitable quality is a growing challenge worldwide. A number of processes are available for the treatment and processing of industrial and municipal wastewater, which are adapted to the substances contained in the wastewater. The treatment of wastewater containing salts represents a particular challenge, as the separation of salt and water requires a very high technical and energy input. By separating salts from water, they can be put to further use and the discharge of saline wastewater into water bodies can be reduced or even avoided altogether. Using the example of saline leachates from residual waste piles in the potash industry, the “HaSiMem” project will investigate whether the membrane distillation process is advantageous compared to the classic form of evaporation of saline wastewater. The joint project, which is funded by the German Federal Ministry of Education and Research, is headed by K-UTEC AG Salt Technologies and will be implemented over the next three years with the partners Fraunhofer Institute for Ceramic Technologies and Systems IKTS, Solarspring GmbH, K+S AG and LMBV mbH.
