Abstract

The operation conditions for the implementation of the Fenton process are of utmost importance because there are problems related to the proportion of H₂O₂ dosage to COD and Fe²⁺ dosage to the specified H₂O₂ amount. The relevant lite-rature shows that COD/H₂O₂ ratios range between 0.0084 and 113.9. Similarly, the COD/Fe²⁺ ratio varies between 0.079 and 292.6, while the H₂O₂/Fe²⁺ ratio varies between 0.09 and 287. Moreover, the ratio of the maximum value to the minimum value used in the operations on the basis of COD is 13560 for COD/H₂O₂ (0.0084-113.9), 2210 for COD/Fe²⁺ (0.079-174.7), and finally 3190 for H₂O₂/Fe²⁺ (0,09-287). The aim of this study was to re-evaluate these values that significantly differ from each other with specific emphasis on textile wastewater and considering stoichiometric ratios. Results showed that values ranging between 0.43 and 4.0 for COD/H₂O₂ and those ranging between 0.75 and 3.0 for H₂O₂/Fe²⁺ are more suitable. The results showed that in a Fenton process con-ducted by dosing H₂O₂ at different times, the TOC reduction efficiencies inc-reased from 80.8 up to 88.9%. Similarly, the color reduction efficiency also rose from 96.5 to 98.7%.
