Microcontaminant removal in secondary effluents by solar photo-Fenton at circumneutral pH in raceway pond reactors

•The operation of RPRs at circumneutral pH by using the Fe3+:EDDS complex is feasible.•Five pharmaceuticals (100μg/L each) were removed at 1kJ/L of accumulated UV energy.•Higher micropollutant removal efficiency in mg/kJ for RPRs than CPCs.•15cm was chosen as better liquid depth for RPR operation at neutral pH with Fe3+:EDDS.•RPRs is a promising technology for micropollutant removal by solar photo-Fenton.
