Another project financed by the Research Fund of the Department of Thermal Sciences has started at the Department of Thermal Sciences. The project entitled "Injection of conditioning liquid before the electrostatic precipitator as a way to increase the efficiency of dedusting and remove wastewater from IMOS." is headed by Arkadiusz Świerczok, PhD DSc, Assoc. Prof. from the Division of Sustainable Energy Technologies. The funds are intended for the purchase of materials and analytical services necessary to carry out the planned research works.

There is a visible trend to achieve zero-emission wastewater management in industrial plants. An example of a source of industrial wastewater can be the IMOS installation (wet flue gas desulphurization installation) in power plants. Wastewater from this source is characterized by a high content of chlorides, sulphates, heavy metals, suspended solids, nitrogen compounds, and moreover, they contain a lot of organic compounds such as COD or TOC. This makes it necessary to expand the sewage treatment plant or build the so-called evaporators in order to meet all the requirements for sewage treated by national regulations and BAT conclusions.

Taking the above into account, a solution was proposed consisting in injection of pre-treated (from mechanical impurities) sewage into the exhaust gas channel before the dust collector (electrostatic precipitator) in order to evaporate it in hot exhaust gases. The aim of the research is to prove the usefulness of the solution consisting in the injection of waste water from IMOS into the hot exhaust gas duct before the electrostatic precipitator in order to remove it and, at the same time, to condition the exhaust gas to increase the efficiency of the dust collector. Additionally, lack of secondary emissions of pollutants contained in wastewater will be confirmed.
