Removal of natural organic matter in water by advanced oxidation processes

In this study, removal of natural organic matter from water was investigated by catalytic oxidation process which is an advanced oxidation process. Removal of THM precursors which is formed by the reaction of natural organic matters with chloride, was performed with the hydroxyl radicals that is produced in catalytic oxidation process. The studies were carried out in three sections. In the first section, decomposition of hydrogen peroxide in pure water with the catalysis of iron coated pumice, in the second section decomposition of hydrogen peroxide in the humic acid medium with the catalysis of iron coated pumice, in the third section removal of humic acid by hydrogen peroxide with the catalysis of iron coated pumice. Removal of humic acid and total organic carbon content in water, and the variation of formation potentials of THM was followed. At the end of this study it was observed that the decompositin of hydrogen peroxide in the pure water and in the humic acid medium with the catalysis of iron coated pumice.
