Integrated hybrid treatment for heavy metal by activated carbon and electro coagulation via new batch design reactor: Clean water production

Abstract

In this search article, an integrated hybrid treatment system combines adsorption activated carbon (AC) and electrocoagulation (EC) to remove lead metal from produced water. The novel used a batch reactor design that facilitates synergistic connections between the two treatment processes. The process was optimized under optimized conditions using Response Surface Methodology (RSM) with a Box-Behnken (BBD. The optimization process conditions include the electrolysis time, pH, activated carbon dose, and current. Lead removal efficiencies reached 88.4% for activated carbon alone, 95.4% for electrocoagulation alone, and 99.8% for the hybrid method at 45 min electrolysis time, pH 3.0, 1 gm of activated carbon dose, and 1 Amp. The results indicate that the combined scheme significantly enhances the lead metal removal rates from the produced water compared to the individual process methods, providing an active solution for the production of clean water. The hybrid process offers an eco-friendly, cost-effective, and sustainable approach to removing metal pollutants from water resources.
