Electrocoagulation is one of the most effective  methods to treat the wastewater, due to low cost ,easy to build, operate  and maintain and low energy consumption. This research is dealing with non-isothermal EC process using computational fluid dynamic (CFD) to simulate the process. The pollutant  is  lead ,and the software is  COMSOL multi-physics 5.5 that is used to solve the partial differential equations of heat and mass transfer , secondary current distribution and fluid flow. One of the most important variables in terms of impact to the process is the applied voltage. Increasing applied voltage leads to an increase in current density and the temperature of the process,  leading to improved lead removal .The rotational anode improves the lead  removal as well, within a limit, which in this case is 50 RPM. Beyond this limit the removal efficiency  becomes negative. The applied voltages that were used in this research are 1.5,3,6 and 10 V. The rotational speeds are 0,10,50 and 100 RPM, and the initial concentrations are 0.5,1 and 2 mol/ M3 .
