THE USE OF BIOLOGICAL PROCESSES FOR WATER PURIFICATION IN THE NATURAL POOL

The use of biological processes to remove pollutants from water is currently the subject of alternative environmental practices. Vegetation and microorganisms as natural elements of the landscape are used to reduce the anthropogenic burden of water bodies. The aim of their use is to study patterns and achieve a reliable functioning of natural processes in artificially created conditions. Biological methods of phytoremediation and biofiltration using live microorganisms are suitable for water purification, where the application of other remediation techniques is too expensive or unusable. These are primarily low-concentration sites requiring only long-term purification, possibly in combination with different methods where the flora and microorganisms are used as a finishing measure. The paper describes the mechanism of biofiltration used for water purification in the Lackovce natural pool situated in eastern Slovakia.
