The Influence of the Configuration of Two Electrochemical Reactors on the Process of Removing Atrazine from Water

In Mexico, atrazine is widely used in agriculture to control broadleaf weeds. The objective of this research was compare removal water and energy consumption between an up-flow cylinder electro-oxidation reactor (UCER) rectangular (URER) using the response surface methodology. each reactor, two titanium (Ti) mesh electrodes (cathodes) one Titanium-Lead Dioxide (Ti-PbO2) electrode (anode). Current intensity effects, electrolysis treatment time, recirculation flow were evaluated. Synthetic with 5 mg/L content used. Optimum values obtained at 2 A electric current, 180 min 200 mL/min rate for both reactors: these conditions 77.45% 76.89% URER UCER respectively. However, showed a significant difference 137.45 kWh/m3 73.63 UCER. Regarding efficiency, 60% reached reactors less (1.5 A–135 min–150 mL/min–25.8 kWh/m3) (0.66 mL/min–20.12 kWh/m3).
