Advantages and Limitations

The principal advantage of chemical oxidation technology is the ability of oxidizing agents to degrade carbonaceous compounds, theoretically to carbon dioxide and water (Roy 1990b). Adequate oxidant and operating conditions (i.e., temperature, pH, and contact time), however, must be present to facilitate a complete reaction. Incomplete reactions can generate partially oxidized products which may require further treatment. Oil and grease in the water can minimize the efficiency of the oxidation process. In addition, UV lamps do not perform well in turbid waters because of the reduced light transmission (Roy 1990a).
