Wastewater from the washing of refrigerated containers of the M.P.S.A.R.C. are discharged directly into the sewerage system without prior treatment, which would generate damage to the sanitary infrastructure, as well as a negative environmental impact since they don’t meet with the Maximum Admissible Values. The objective was to evaluate the coagulation-flocculation and adsorption system at laboratory level for the reduction of the physicochemical parameters from wastewater reefer containers washing through an experimental design. A population of 1 m3 / h and a sample of 26 liters was considered. In the Coagulation - Flocculation process, Organic coagulant, Ferric Chloride and Aluminum Polychloride were used in doses of 1, 2 and 3 ml/L and a constant dose of 3 ml/L of anionic polyacrylamide as flocculant. Adsorption process 500 g of granular activated carbon was applied evaluating 5 and 10 minutes of contact. The optimal dose for each coagulant was 3 ml/L, and Ferric Chloride was the most efficient; while in the adsorption process, the most reduction of COD and turbidity was after 10 minutes of contact. Finally, after system treatment, 98.11%, 98.88%, 99.84%, 99.50%, 99.90% of BOD5, COD, TSS and Oils and Greases respectively were reduced; comply with the Maximum Admissible Values.
