Abstract – The project work was carried out to investigate
oxidation process, etc. These methods are also used to treat Spent wash to get better results for removing the contaminated pollutants present in it [2]. Among all the methods AOPs are the suitable method to treat DSW. AOPs have different methods in which Fenton process is the most effective method to treat spent wash. Fenton process is the combination of H2O2 and Fe3+ ions which together make Fenton reagent, effective in treating polluted wastewater to remove recalcitrant components [2].
the Treatment of Distillery Effluent by using Advanced Oxidation Process (AOPs). Recent trends proposed AOPs for oxidizing complex organic compounds or recalcitrant organic matters present in the Distillery Effluent to simple harmless compounds. Fenton oxidation process is one of the processes of AOPs, combination of Hydrogen peroxide and Ferrous ion reacts to form active Hydroxyl radical. Electro Fenton Process is an electrically aided Fenton reaction by the use of Electrodes. Application of the Response Surface Methodology (RSM) to check the Electro-Chemical Oxidation of Distillery Spent wash by using Aluminum electrodes. The Variables considered for the study are Fenton Dosage, Reaction time and Applied Current. COD, Colour, Turbidity and TDS are the response factors under consideration.
2. MATERIALS AND METHODOLOGY 2.1 Materials To carry out the experiment various glassware, reagents (Fenton reagents), Chemicals and some instruments are used in the laboratory.
Key Words: Distillery Effluent, Advanced Oxidation Process, Electro Fenton Process, RSM, COD.
2.2 Methodology
1. INTRODUCTION
The method adopted to treat Distillery Effluent is AOPs in which Electro Fenton process is suitable for the treatment of Distillery Effluent.
Distillery industries have been around for a long time, it is an industry that produces alcohol, rectified spirit, spirit and ethanol, as well as a large amount of wastewater. Because of large amount of wastewater produced by the alcohol industry in India, it is extremely hazardous to the environment. This distillery wastewater, also known as distillery effluent, is commonly referred as “Spent wash” or “Stillage”. This DSW is highly recalcitrant, with high complexities, it has more BOD, COD, TDS, Turbidity, Colour, Odour [1]. This molasses based alcoholic distillery industry produces wastewater, which typically ranges from 10-15 liters per liter of alcohol produced in the distillery industry process and has characteristics such as dark brown colour, high BOD and COD values. When untreated Distillery Spent wash or alcoholic wastewater is discharged into water bodies or open sources, it can cause severe or unmanageable environment damage, such as disturbing underground or surface water and depleting soil properties. Although distillery wastewater has a negative impact on the environment. Therefore, proper treatment method is required to treat the wastewater from the distillery industry before discharge is more required. There are plenty of old technologies to treat industrial wastewater like Adsorption method, Physio-chemical method, Membrane technology, Aerobic treatment, Electro-coagulation method, Advanced

2.3 Electro Fenton Process The EF process is a type of AOPs that is carried out electrically using electrodes. This process is simpler than other methods because it leads to the resurgence of Fenton reagent products and further aids in the oxidation reaction. 2.4 Experimentation 1. Raw sample (Distillery Effluent) was collected from the distillery industry and transferred to the laboratory with suitable conditions for further experimentation. 2. Sample was initially investigated for its basic parameters like pH, COD, BOD, TDS, EC, Turbidity and Chlorides. 3. This sample is then added to beaker (1000ml) and placed on magnetic stirrer by adding Fenton reagent (Hydrogen peroxide & Ferrous ions in 1:5 ratio). The sample is stirred well it is allowed to treat for certain time according to the RSM worksheet data. 4. After the treatment sample is allowed for settlement and then collected to know the % removal of COD.
