Coal Mine I Poland

1000 610 ZERO BRINE

Silesian University of Technology is demonstrating the circular economy principles in the coal mining industry in Laziska Górne, Poland. The aim is to decrease the energy consumption by 50% compared to the energy consumption of a reverse osmosis-vapour compression system which represents current best practice.  The coal mine water, having salinity of ca. 23 g/L and rich in calcium sulphate, will be treated using integrated system consisting of nanofiltration, reverse osmosis and electrodialysis with the aim to recuperate valuable raw materials, such as concentrated brine, magnesium hydroxide, and high quality RO permeate.
