The treatment of domestic and industrial waste water generates big quantities of sludge. These residual sludge raise important environmental, economic and technological problems. The decrease of the quantity of produced sludge and the degradation of the organic matter are very important. A new Treatment process was finalized in order to oxidize the organic matter in sludge. This work studies the oxidation of sludge of a water-treatment plant of a dairy farming by the peroxide of hydrogen (H2O2). Several experimental laboratory tests were made under various conditions especially: → Oxidation of sludge by H2O2, at ambient temperature and pressure → Oxidation of sludge by H2O2, at ambient pressure high temperature (100°C) → Oxidation of sludge by H2O2, at ambient temperature and pressure, in the presence of Fe2+ ions The results showed that the ferrous ions can catalyse peroxide of hydrogen to promote of the organic matter degradation. The oxidation of sludge by peroxide of hydrogen H2O2 in the presence of iron salts, coupling H2O2/Fe2+ what we call reagent of Fenton, reduces in a significant way the organic matter of sludge and improves the quality of the product: the rate of the total organic carbon (TOC) was reduced from 423.5 g/kg to 36 g /kg.

The physicochemical characterization of Olive Oil Mill Wastewater (OOMW) from Meknes, Morocco, showed high organic matter, measured in terms of chemical oxygen demand to 320 g/L. It is also characterized by high rate of phenolic compounds with 8.75g/L. Treatment of OOMW by permanganoferrates of potassium, superoxidants of synthesis is a promising alternative. Optimization of treatment parameters has shown that for an attack time of 30 minutes, we were able to achieve nearly 100% reduction in COD, which showed the effectiveness of treatment and the oxidizing power of these compounds for different molar ratios especially of 3 and 4. That can be explained by the abundance of iron VI.
