Variability in required ozone doses for removing pharmaceuticals from wastewater effluents

Aim of study. The aim of the present study was to investigate the ozone dosage required to remove active pharmaceutical ingredients (APIs) from biologically treated wastewater of varying quality originating from different wastewater treatment processes. Methods. Secondary effluents from six Swedish wastewater treatment plants (VWVTP) were spiked with 42 APIs (nominal concentration 1pg/L) and treated with different 03 doses (0.5-12.0 mg/L ozone) in bench-scale experiments (Antoniou et al, 2012). Concentrations of APIs were measured by SPE extraction using OASIS HLB cartridges followed by quantification using LC-MS-MS (Grabic et al, 2012).. Results. For each wastewater effluent a profile of sensitivity of each API to a range of ozone doses were generated as shown in Figure 1.
