The wastewater from the chemical tanker unloading industry contains a large quantity of organic compounds with a high polluting potential. TRALSA, in its process of unloading chemical tankers with Toluene and Xylene, generates waste from the water-product mixture due to the procedure currently used. In Tralsa, it was proposed to use advanced oxidation processes to treat its contaminated wastewater that is generated in ship discharges. These processes are those that involve the generation of hydroxyl radicals (°OH) in sufficient quantities to degrade the organic matter present in an effluent, such is the case of the Fenton process. Initially, a typical wastewater sample was characterized in a laboratory, finding a COD of 476 mg/L and BOD5 of 220.3 mg/L, then Fenton was applied at room temperature with different ratios of Fe2+/ H2O2 (1: 1, 1: 3 , 1: 5, 1: 7, 1:10, 1:15, 1:20, 1:25, 1:30, 1:40), using a contact time of 45 min, pH equal to 3.5, it was left the samples at rest to finally pass them through a filter and send them back to the laboratory. With the results, a COD of 36 mg/L and BOD5 of 15.1 mg/L were obtained, with this, the ratio of 1:20 (Fe2+/ H2O2) was established as the optimal dosage. Finally, the working conditions for the treatment system for these waters were a molar ratio of 1:20 (Fe2+/ H2O2), contact time of 45 min, pH equal to 3.5, typical sample of 476 mg/L of COD, 220.3 mg/L of BOD5 and at room temperature with which the removal of 92.4% of the organic matter on a laboratory scale and 89.3% on an industrial scale is achieved, in compliance with the regulations Supreme Decree No. 037-2008-PCM, Limits Maximum Allowable Liquid Effluents for the Hydrocarbons Subsector.
