A Novel Control System Approach to Enhance the Efficiency of Solar Photo-Fenton Microcontaminant Removal in Continuous Flow Raceway Pond Reactors

•A control system for the continuous flow operation of solar photo-Fenton was designed.•Two micropollutant removal targets were evaluated: 70% and 90%.•Disturbance rejection was successfully achieved.•Cost efficiency improvements from 45 to 50% were achieved.•Water treatment capacity was studied over different seasons of the year.
