The pharmaceutical effluent was remediated by employing batch and Batch Recirculation (BR) of fenton, Electro
Oxidation (EO) and Electro Fenton (EF) processes to detach the organic compounds from the pharmaceutical
wastewater using rotating disc reactor. Synthetic wastewater was modelled with Total Organic Carbon (TOC) of 298
mg/L. EF process showed enhanced results which could be attributed to the generation of large amount of hydroxyl
radicals by which the generation of ferrous ions by the reduction of ferric ions reacted with hydrogen peroxide along
with the anode. The optimum conditions for EF process were Fe2+=0.2 g/L, H2O2=0.9 mM, Current Density
(CD)=15 mA/cm2, rpm=500 rpm, pH=3.5 and Fe2+=0.2 g/L, H2O2=0.9 mM, CD=10 mM/cm2, pH=3.5, rpm=500,
flow rate=60 L/h for batch an.. View more»
