The wet oxidation (WO) regeneration of powdered activated carbon (PAC) used for reverse osmosisconcentrate (ROC) treatment was studied. The exhausted PAC was regenerated at different temperaturesand times. The experimental results indicated that the optimum regeneration condition could beachieved at a temperature of 200 8C for 60 min. The mass of carbon in the solid, gas and liquid phasesbefore and after the PAC regeneration was balanced in different regeneration conditions. A molecularweight (MW) distribution of organic matter (OM) in the effluent treated by the PAC regenerated atoptimum conditions was performed.
