The aim of this study was to examine the best electrode design for electrocoagulation process with removal performance, reduced passivation on surface, and lower energy consumption requirements removing Chromium (Cr) Lead (Pb) from leather tannery effluent. Three different electrodes were compared: non-rotating disk (NRDE), rotating (RDE) mesh (RDME). All used observe a reduction in surface its effects performance Cr Pb. material iron. maximum efficiency obtained = 87.9% Pb 97.5% under following operating conditions: pH 7, treatment time 90 min, current density 6.57 mA/cm², RPM 80. results show that electrical requirement treating chromium lead using RDME 4.5 kWh/m³, which found be than observed various other studies According results, shows highest specific compared NRDE RDE. can efficiently employed at larger scale

Heavy metals are commonly found in agricultural and industrial wastewater. Because of their high toxicity negative effects on human health, removal from wastewater is great importance. Electrocoagulation a promising technology for the heavy metals. The metals, namely, lead, cadmium, zinc, chromium, nickel, manganese, copper as individual elements mixtures synthetic real by electrocoagulation, was studied using aluminum electrodes anodes stainless steel cathodes monopolar connections different reaction times current densities. results show that percentages were 100% lead after 20 min at 5 mA/cm2, 98% cadmium 40 15 zinc nickel chromium 60 manganese mA/cm2. showed similar patterns but lower values than those elements. Pseudo-second-order kinetic model best describes kinetics investigated.
