Modern technologies for radium removal from water - a review

EasyChair Preprint 1431

Abstract

In the formation waters, occurring in coal mines in the Upper Silesian Coal Basin,  Poland, radium isotopes are present which may cause damages to the natural environment. In several collieries the radium removal from mine water was necessary to mitigate negative results of radium release with mine effluents. The most efficient method is based on application of barium chloride, implemented in full technical scale in two collieries.

During the period of exploitation of underground treatment stations for radium removal some drawbacks of the application of barium chloride have been found. The most important ones were as follows: the need for continuous feeding of the powdered chemical and the maintenance of installation. Therefore investigations were focused on such methods, which would allow automation of the process, or would be a passive ones. It has been found, that two possible methods were – application of zeolite for radium removal from water in form of a passive barrier or application of barium chloride as a solution, which would give the opportunity to make the process of feeding fully automatic.

In this paper results of comparison of different techniques is given, showing possibilities of application of different methods of radium removal, its advantages and drawbacks.

Keyphrases: collieries, pollution, radium, water purification
