Abstract	Sludge generation is a primary concern in Fenton treatment of recalcitrant wastewaters. Researchers studied mineralization  of petroleum refinery effluent (PRE) and the accompanying sludge generated in treating PRE. The mineralization level of 53% at optimum conditions produced 0.16 L of wet sludge per litre of wastewater. Further study of the sludge properties assessed the ease of handling and potential reuse of the sludge. Study results confirmed that the sludge generated could be managed systematically with appropriate operating conditions.
