Resumen
WE STUDIED AND QUANTIFIED THE ELIMINATION OF SUNFLOWER OIL FROM A WASTEWATER INFLUENT USING A BIOLOGICAL TREATMENT BY ACTIVATED SLUDGE. ESTIMATION OF THE BIODEGRADED MATERIAL WAS OBTAINED DOING A MASS BALANCE, AND WE CONDUCTED A FOLLOW-UP OF THE DIFFERENT OPERATIONAL PARAMETERS AND DESIGN. WE DELIVERED INFORMATION ABOUT THE OPERATION OF A SYSTEM FOR TREATMENT BY ACTIVATED SLUDGE FED WITH AN INFLUENT WITH SUNFLOWER OIL AND SACCHAROSE. THE INFLUENT WAS PREVIOUSLY AGITATED BEFORE ENTERING THE EFFLUENT SLUDGE IN A LAB-SCALE PLANT. THE WORKING RANGE FOR OIL CONCENTRATION WAS 100 TO 850 MG/L IN THE INFLUENT. BIODEGRADATION WAS IN THE RANGE OF 60% TO 51%. THE PROCESS WORKS BETTER WITH A HIGH INITIAL CONCENTRATION OF BIOMASS (7500 MG/L) IN ORDER TO ABSORB THE IMPACTS CAUSED BY THE OIL ON THE MICROORGANISMS. THE LOWEST TOTAL SUSPENDED SOLIDS CONCENTRATION WAS 4500 MG/L. THE ELIMINATION OF SUNFLOWER OIL IN BIODEGRADATION AND FLOTATION WAS ON THE ORDER OF 90%.
