Abstract

 

Electrocoagulation has demonstrated significant removal effectiveness of grease, oils, biodiesel and microplastics in wastewater. The optimum operation parameters for industrial lubricant oils removal in wastewater were defined in this investigation by using a parallel array of two pair of aluminum 6061 electrodes. The experiment was performed using a rectangular batch reactor made up of glass where an analogous water polluted with 1 ml of industrial lubricant oil waste was treated applying a current density of 40 A/m2 in a range of 10 to 50 minutes and varying the addition of 100 ml of a 2 g/L NaCl solution. The optimum operating conditions within the range analyzed achieved 91% of removed lubricant after 30 minutes of treatment and using the electrolyte additive. Furthermore, the analogous treated water contained 1.6 mg/L of Total Suspended Solids (TSS), 8.44 pH units, 0.97 Nephelometric Units of Turbidity (NUT) and 14.33 color units in the platinum/cobalt scale. These results make the treated water a possible candidate as service or irrigation water.

Keywords: Acorn extract, Natural antioxidant, Oxidation, Meat burger.
