Investigations were carried out in a laboratory scale in a rotating biological contactor in which cathode was made of stainless steel disks with immobilized biological membrane, whereas electrode made of stainless steel or steel sheet or aluminium one were used as anode. In the first stage of the experiment, the oxygenation capacity of the rotating biological contactor was investigated under conventional conditions – without the flow of electric current; whereas in the second stage of the study – under the flow of electric current with density range from 0.2 A m⁻² to 1.5 A m⁻². The highest values of oxygenation capacity (OC) were obtained in the system in which electrode made of stainless steel served as anode, and the lowest ones – in the conventional system.

Badania prowadzono w skali laboratoryjnej na elektrobiologicznym złożu tarczowym, w którym katodą były tarcze ze stali nierdzewnej z unieruchomioną błoną biologiczną, anodą – jedna z elektrod – elektroda ze stali nierdzewnej, z blachy stalowej lub aluminiowa. W pierwszym etapie badano zdolność złoża biologicznego do natleniania w warunkach konwencjonalnych – gdy nie przepływał prąd elektryczny, w drugim – w warunkach przepływu prądu elektrycznego o gęstości z zakresu od 0,2 A m⁻² do 1,5 A m⁻². Najwyższe wartości OC (zdolności natleniania) uzyskano w układzie, w którym anodą była elektroda ze stali nierdzewnej, a najniższe w układzie konwencjonalnym.
