THIS RESEARCH STUDIES THE BIODEGRADATION OF SUNFLOWER-TYPE VEGETATIVE OIL IN TWO PROPOSED ACTIVATED SLUDGE SYSTEMS, THE FIRST ONE TO BIOLOGICALLY TREAT AN INFLUENT CONTAINING ONLY VEGETATIVE OIL AND THE SECOND ONE TO TREAT A MIXTURE OF VEGETABLE OIL PLUS SACCHAROSE. THE PURPOSE OF THESE ANALYSES IS TO EVALUATE THE DIFFERENTIAL IMPACT CAUSED BY THE SOLUBLE SUBSTRATE SACCHAROSE ON THE REMOVAL OF VEGETATIVE OIL. VEGETATIVE OIL BIODEGRADATION IN BOTH SYSTEMS WAS STUDIED AND QUANTIFIED VIA INTEGRAL MASS BALANCE, AND RELEVANT OPERATING PARAMETERS WERE MONITORED. THIS EXPERIMENTATION BASED ON THE MASS BALANCE ESTIMATION OF BIODEGRADED VEGETATIVE OIL SERVES AS A REFERENCE TO UNDERSTAND THE EFFECT OF SOLUBLE SUBSTRATES PRESENT IN MIXED WASTEWATER ON OIL BIODEGRADATION. INFORMATION WAS GENERATED ON THE PERFORMANCE OF THE TWO ACTIVATED SLUDGE TREATMENT SYSTEMS. BOTH INFLUENTS WERE PRE-STIRRED BEFORE THEY ENTERED THE BENCH-SCALE ACTIVATED SLUDGE PLANTS. THE WORKING RANGE FOR SUNFLOWER OIL CONCENTRATION WAS 120 TO 520 MG/L FOR THE INFLUENT WITH SUNFLOWER OIL AND 180 TO 750 MG/L FOR THE INFLUENT WITH SUNFLOWER OIL AND SACCHAROSE. BIODEGRADATION WAS IN THE ORDER OF 56 TO 72% AND 47 TO 67%, RESPECTIVELY. THE REMOVAL OF SUNFLOWER OIL IN BIODEGRADATION AND FLOTATION WAS IN THE ORDER OF 90% IN BOTH SCENARIOS.

THE NEED ARISES TO SEEK NEW DEPURATION TECHNOLOGICAL RESPONSES AIMED AT THE REUSE OF WASTEWATER, WHICH REQUIRES THE DEVELOPMENT AND PROMOTION OF ECONOMICALLY AND ENVIRONMENTALLY SUSTAINABLE TECHNOLOGIES. IN THIS PAPER, IT STUDIES AN IMPROVEMENT TO A DISINFECTION SYSTEM SUSTAINABLE, LOW-COST, PATENTED IN 2019, AND BASED ON SOLAR ENERGY. THE WATER PASSES THROUGH A CANAL OF REFLECTIVE MATERIAL IN THE CONTINUOUS REGIME, AND IN THE BATCH REGIME, THE WATER REMAINS IN THE CANAL. THE PANELS ARE LOCATED PARALLEL TO THE LATERAL FACES OF THE CANAL. THE FRACTION OF THE RADIATION REFLECTED OUTSIDE THE CANAL REACHES THE REFLECTIVE SIDE PANELS THAT RETURN THE RADIATION TO THE CANAL. THESE PANELS CONCENTRATE THE RADIATION IN THE CANAL THROUGH REFLECTION. THE DISINFECTANT CANAL WITH FINS AND SIDE PANELS USES ULTRAVIOLET RADIATION TO ELIMINATE THE BACTERIAL LOAD CARRIED BY TREATED WASTEWATER. FOR THIS REASON, THE PRESENT WORK ANALYZES THE INCIDENCE IN THE AREA OF INFLUENCE OF THE DISINFECTANT CANAL. WHEN REFLECTIVE ALUMINUM MIRRORS WERE INSTALLED ON THE SLOPING WALLS OF THE CANAL, GLOBAL RADIATION INCREASED BY 4%, WHEN THEY WERE USED ON THE SIDE PANELS, IT INCREASED 3%, AND WHEN THE ALUMINUM MIRRORS WERE USED ON THE CANAL WALLS AND SIDE PANELS, IT INCREASED 8%. THE IMPORTANT THING ABOUT THIS WORK IS THAT IT OPENS WINDOWS FOR IMPROVING THE SYSTEM THROUGH MATERIALITY SO THE NEW CHALLENGE IS THE SEARCH FOR THE OPTIMAL MATERIAL CONSIDERING THE IMPACT ON GLOBAL RADIATION AND CONSEQUENTLY ON THE BACTERIOLOGICAL ELIMINATION.
