The research activity is focused on studying the mass transfer mechanisms in liquid-liquid and solid-liquid systems and development of various separation methods and techniques like extraction, liquid membrane separation, ionic liquids separation, adsorption, etc. The application is in “green” processes using non-toxic and low-pollutant chemicals, recovery of valuable substances or removal of harmful substances from wastewaters, hydrometallurgical processes for recovery of metals, manufacturing of valuable natural bioactive products extracted from botanicals and intended for pharmaceutical, cosmetic and nutritional uses.
The hydrodynamics and mass transfer in packed columns is another traditional research field. The studies include development of new types of high efficient packings and devices for uniform distribution of the liquid phase and elimination of the harmful wall flow effect. The latter allows for reliable transfer of laboratory test results to industrial scale.
Investigations are carried out also on treatment of industrial and domestic wastes through pyrolysis and incineration with utilization of the obtained heat.
