Chapter 5 Conclusions and recommendations
5.2 Recommendations for future work
Based on the findings of the present study, the following points are suggested for future work:
(1) Further research is necessary to evaluate the effects of factors other than pH, dosage rate of H2O2 and dosage of Fe3+, i.e. light intensity, temperature and H2O2/Fe3+ ratio, on the carbofuran degradation. This knowledge can provide a complete understanding in degradation and mineralization of carbofuran in a complex system conditions.
(2) Since the Fe3+ solution in this study was added once in batch experiments, it can be expected to reduce the usage of iron source by continuous addition at fixed flow rate under similar operating conditions.
(3) There are only five intermediates detected in the present study. The residual DOC value means that other intermediates could be exist in the system. Further research is necessary to quantify the intermediates and establish the degradation pathways of carbofuran using photo-Fenton reaction.
(4) The present study has already demonstrated that carbofuran can be effectively treated via photo-Fenton process. And, the photo-Fenton process was successfully initiated as a pretreatment to enhance the biodegradability and reduce the toxicity of carbofuran. The feasibility of coupling photo-Fenton process and biological treatment in acclimated batch reactors needs to be further investigated.
