Modelling and Simulation for Removal of lead ions (Pb+2) from a synthetic wastewater by electrocoagulation using aluminum (Al) as a rotating electrode in a Batch Process by using COMSOL Multiphysics

There are some technique that utilized for wastewater treatment, electrocoagulation for wastewater treatment, which has heavy metals (lead compounds) as contaminants.modeling was utilized to simulate the batch (EC) unit in this study.To model species transport, current and fluid movement, the diffusion, Nernst that governs this issue has been solved utilizing commercial software (COMSOL 5.4).Three main variables that impacted the performance of the lead EC process were tested: different starting lead amounts (200, 300, 400, 500 ppm), various applied voltage (2.5,5 V), and various anode rotating velocities (50,100, and 150rpm).The removing rates of lead (removing effectiveness) reduced as the original lead level increased, according to the findings.with increasing applied voltage, but not wi beginning to drop at 150 rpm.Since the instability of the produced flocks, the eliminating effectiveness progressively decreases.Utilizing (Al/St.St) electrodes, the best rem velocity.
