Determination of biochemical oxygen demand with continuous recording of oxygen uptake

Methods involved in the treatment of four representative pharmaceuticals in hospital wastewater using sonochemical and biological processes

“…Before the application of the aerobic biological method (BS) to HWW, a control test for the experimental system is performed, using glucose (at 40 mg TOC L −1 , glucose is a reference substance for biodegradation [25 , 26] ) and measuring oxygen consumption. Once the proper performance of microorganisms is established, the BS is applied to the HWW sample for 36 h, also monitoring the oxygen consumption.…”
