Abstract

Nowadays, many industries such as textile, refinery, chemicals and plastics produce the waste with organic matter and colour [1]. Because of population rapid growth and the associated increase of industrial activities and diminishing avalibility of water resources, conventional water and wastewater treatment processes becomes insufficient [2]. Hazardous wastes from industrial, commercial or municipal operations are the biggest challenge of today’s engineering [3]. In many industrial processes biological treatment methods cannot be used because of toxicity of the waste. Sometimes chemical coagulation and active carbon sorption are not effective enough and are too expensive [1, 4]. Advanced oxidation processes (AOPs) have some advantages in COD/BOD removal. Hydroxyl Free Radical (•OH) may be use as a AOPs method to reduce COD/BOD levels. It will also remove both organic and oxidisable inorganic components. AOPs are a high efficiency physical-chemical processes because they are able to do changes in the chemical structure of the wastes. Some other type of radicals, generated radicals, are able to oxidize organic pollutants mainly by hydrogen abstraction. Generating of organic free radicals (R•) may lead to mineralization of organic matter [5]. In this paper the Free Radical Technology (FRT) and its usage to remove COD/BOD from wastewater in oxidation processes is introduced. Also its advantages and applications are presented.
