Abstract: Management of Industrial wastewater is one of the complicated problems in this world. Many technologies and methods are implemented for the industrial wastewater treatment and got the maximum efficiency of removal using various chemicals and materials. But, the management of sludge from various treatment technologies is comparatively low. Various methods such as physio-chemical, biological, Membrane process, Adsorption, Advanced oxidation process and electrochemical processes were used for the treatment of different effluents. Due to the limitations of the conventional sludge stabilization processes are not able to remove the heavy metals ions from waste activated sludge to make it reliable enough to be utilized as fertilizer in agricultural lands and farms. Advanced Oxidation Processes (AOPs) is the outstanding technique for treatment of polluted wastewaters containing intractable organic pollutants. AOP utilize the tough oxidising power of hydroxyl radicals that can trim down organic compounds to nontoxic end products. The most studied AOPs are photochemical-based processes (PAOPs), as UV/hydrogen peroxide, heterogeneous photo catalysis (HP), photo-Fenton (PF), UV plus ozone and combination of these technologies. Currently, advanced oxidation process is among the most frequently used approaches to remove pollutants that have low biodegradability or high chemical stability. These methods are depend on the generation of hydroxyl free radical (HO*) as a strong oxidant for the destruction of compounds which cannot be oxidized using conventional oxidants. This paper reviews that, the application of AOP for the removal of different kinds of toxic pollutants from the industrial wastewater.
