AOP has its distinct space in water treatment. One who chooses AOP has clear idea in his mind that he wants to avoid several uncertain chemical and biological dosing. He also should be clear that despite of high cost and little more energy, he is yielding safe water. To my personal experience working exclusively with AOP in India with most hazardous industrial waste waters, I can certify that OPEX for AOP is at least 10% less than any conventional or advanced non AOP process on per Kg COD settlement basis.  Every coin has two sides and Nick Nicholas is bold enough to highlight the grey side of the AOP coin. But don't forget, coins don't loose their value even when they are little dirty!

Thanks Niraj, yes I wanted to be balanced in addressing both the positive as well as some negative aspects of this AOP process. However, you are correct that coins don't loose their value when they are a little dirty! The AOP benefits outweigh the disadvantages especially in certain industrial waste waters. At GWT, we work with our local partners using the AOP process were appropriate for industrial waste water applications.
