Comparison of classical chemical and electrochemical processes for treating rose processing wastewater.

In this study, the treatability of rose processing wastewater was investigated by using electrocoagulation (EC) methods compared to classical chemical (CC) and Fenton application (FA) processes. High chemical oxygen demand (COD) and dissolved solids contents were detected in the wastewater. Among these treatment applications, it was found that the EC unit is the most effective treatment technique for removal of both COD and turbidity. The removal efficiencies of COD and turbidity were as high as 79.8% and 81.4%, respectively, and the reaction time was 20 min for EC methods.
