Introduction: Because of high water consumption, carpeting industries produce high levels of waste water which as a result of using different dyes in production processes their treatment feasibility is very low which is a threat for environment. This study conducted to evaluate the treatment feasibility of carpet industry wastewater using Fenton.

Method: This descriptive-analytical study conducted in a batch reactor. From carpeting industries 72 wastewater samples were taken. The effect of changing the level of variables such as pH, Hydrogen peroxide, and Iron sulfate on wastewater treatment feasibility was measured and by repeating the experiments the optimum level of each variable was determined with a confidence level of 95%. TOC was measured using ANATOC II TOC measurement instrument. All experiments were performed according to standard method. Data were analyzed using SPSS and Excel software.

Results: Results indicated that the best pH for removal of organic material in Fenton process is 3. COD removal efficiency revealed to be 95% when using 5.5 g/L FeSO4 and 385 g/L H2O2 in pH 3. H2O/Fe2+ ratio for maximum removal of COD was 95-10.

Conclusion: According to our results, carpeting wastewater organic materials can be efficiently removed using Fenton process. It was also revealed that factors such as pH, the amount of reagents, and H2O/Fe2+ ratio affect the Fenton oxidation process.
