| Abstract | This work consists of the analysis of three reactors configurations applied to photochemical advanced oxidation processes through process UV/H2O2. The settings of these reactors were analyzed at three different flow rates, 20 L h, 25 L h 1 and 30 L h. Evaluations were carried out hydrodynamic flow through the passage as the flowrate mentioned a 5% solution tracer, Bordeaux red dye, allowing construct curves residence time distribution (RTD) for each reactor. The analysis of these curves provide important information regarding the operation of the reactor, showing the limitations of each setting, either by dead zones or dispersions inside. Were analyzed discoloration of effluent studied synthetic wastewater based on six foods dyes, Tartrazine Yellow Dye (CI 19140), FD & Sunset Yellow (CI 15985), FD & C Red Bordeaux FCF (CI 42090), FD Erythrosin (CI 45430), FD blue Indigo Carmine (CI 73015) and Dye Brilliant Blue FCF (CI42090). In this phase of the study allowed an analysis of qualitative efficiency of the system, showing the removal of color in each of the reactors configurations from which we obtained values of 100% in the reactors R2 and R3, the 3 rd and 2 recycle, respectively, the reactor R1, presented limitations, requiring four recycles. It also conducted an analysis of the energy reactor, in order to determine the costs involved in this type of treatment. In hydrodynamic analysis had up results indicating presence of dead zones and short circuits in the reactors, and the variation of the flow enables more efficient use of low flow in R1, R2 in high flow, and R3 in intermediate and high flow. From the calculation EEO, it appears that the treatment efficiency is approximately (average) 23,843 kWh m for the R1, 25.932 kWh m -3 for R2 and 22.065 kWh m -3 for R3. |
