This study aimed to determine the influence of the electric current density on the rate of nitrogen compounds removal (rN) and the specific rate of denitrification (rD) in a rotating electrochemical disk contractor (RECDC) and a rotating electro-biological disk contactor (REBDC). In REBDC and RECDC. the cathode consisted of disks with immobilized biomass and disk. from which biofilm w... https://theplayfulcollectivees.shop/
