I am currently working on collecting literature based on the available treatment technologies for industrial effluents. There are vast variety of methods physical, biological and Advanced oxidation processes used for the elimination of organic contaminants from industrial effluents. I am trying to compare and evaluate these technologies to propose best or better treatment techniques from industrial economics point of view. Kindly give suggestion/ advises regarding how to write a clear and concise review paper on the above mentioned topic from the available large quantity of literature?
