ANALYSIS OF COUPLED SYSTEM EFFICIENCY DISSOLVED AIR FLOTATION (DAF) - FENTON IN WASTEWATER TREATMENT PROCESS FROM PALM OIL EXTRACTION
The steady growth of the population and industrial sector demand large volumes of water in their processing of resources, it causes daily generated huge amounts of wastewater. The system Dissolved Air Flotation (DAF) coupled to a Fenton system emerges as a proposal for the treatment of industrial effluents from the process of extracting palm oil. Thereby achieving optimize and reduce both the time and the area for treatment. FAD system was operated with 4.5 atm pressure, retention time 30 min and concentration of 8 g / L of total solids (ST). Clear phase recovered was oxidized by Fenton system using 100 mL per reactor under an arrangement bifactorial (H2O2/Mn+2) 5 x 5. The five H2O2 concentrations used in this design were 3000, 4500, 6000, 7500 y 9000 mg/L and the manganous sulphate concentrations tested were 1000, 1500, 2000, 2500 y 3000. Under de best conditions was achieved up to 100% removal of suspended solids (SS), 79.81% total solids (TS), 93.44% Chemical Oxygen Demand (COD) and 95.17% fats and oils (G & A).Keywords: Advanced oxidation processes, Chemical oxygen demand, Wastewater treatment.
