The results of the project “Conditionally Reagent-Free Systems of Hospital Drainage Processing”

The project called Conditionally Reagent-Free Systems of Hospital Drainage Processing won in 2020 in the contest Science for the Safety of Man and Society of the National Research Foundation of Ukraine. This project was created and done by scientists of Ukrainian State University of Chemical Technology, Dnipro State Medical University, and Oles Honchar Dnipro National University. In December 2021, the work was completed.

Oleksandr Velichenko, Head of the Department of Physical Chemistry of SHEI USUCT, a Corresponding Member of the National Academy of Sciences of Ukraine, was the leader of the project. In the interview with a representative of the National Research Foundation of Ukraine Svitlana Galati, he summed up the work and spoke about the prospects for implementing the results in production.

The team of scientists has created a device that allows disinfecting hospital drains without the usage of chemical reagents. The device has a built-in DC source, a pump that pumps the liquid, electrochemical cells with special electrodes. Pharmaceuticals pass through the cells and lose their activity. Then, strong oxidants (hypochlorite, ozone) and hydrogen peroxide are formed in the aqueous solution. They create an oxidizing medium for effective disinfection. Oxidizing agents neutralize environmentally dangerous substances (viruses and bacteria) and help destroy medicines. Scientists plan to create and test a prototype of a modular flow system for hospital effluent treatment and test it, which is likely to be of interest to health care facilities.
