Descripción : In Ecuador the field of car washing and lubrication not only represents uncontrolled growth, but is also a source of pollution to the water resource. The effluents from the car wash and lubrication were characterized by having high amount of oils and greases (1286 mg / L), anionic surfactants (6.63 mg / L), basic pH ( 8), aluminum (25.69 mg / L), COD (816 mg / L) and high turbidity (310.6 NTU). The goal of this research was to treat wastewater from car wash and lubrication in San Isidro del Inca by bio-adsorption processes and coagulation-flocculation technologies. There were used three natural waste materials as bio absorbents: sawdust, sugar cane bagasse and coir. Experimental designs were applied as a result they determined that 0.3 g and 0.3 mm of particle size, the coir obtained high efficient in the adsorption of oils and greases (97.95 percent), aluminum (95.76 percent), copper (97.59 percent) and total chromium (92.86 percent). Through the chemical treatment two types of chemical coagulants were used (PCA and FeCl3), coagulant-flocculants dose and the effect of salinity. The greater efficiency in removing turbidity (99.92 percent) was obtained when a dose of NaCl was applied with 500 μL of PCA 5 percent and 600 Μl of PA to 0.1 percent; while, at the same dosage without salinity was reached 99.76 percent. These results suggest that salinity can be used as an alternative to promote the generation of chemical coagulation improving the turbidity and quality of sludge formed after treatment. The treated water fulfilled the maximum permissible limits according to the Ecuadorian environmental legislation (TULSMA) for discharges to body waters.
