Abstract

Fish meal processing industries turns the raw fish into a commercially edible form. The wastewater generated from this industry consists of organic pollutants BOD,COD, Total solids, high amount of odour. Since the industry process the raw fish the wastewater has high amount of COD. Normally in the fish meal processing industry they use chemical and biological methods to treat the wastewater, by adopting these methods for treatment, high amount of sludge is produced after the treatment process is over.Again we have to find another method for disposing the sludge. By using the advanced oxidation process we can eliminate the sludge production during the treatment process. Advanced oxidation process can be done using uv/H2O2 method, ozone based AOP,photocatalytic oxidation with TiO2, electrochemical advanced oxidation process. In all the above mentioned process the pollutants are targeted using different parameters such as UV rays, H2O2, electricity. However by using hydrogen peroxide, ozone, UV the complete reaction will not take place and the intermediate products remains in the water as pollutant To overcome this problem Electrochemical oxidation method can be adopted.This method is useful in breaking the most resistant organic compound.
