This paper describes the use of a simple experiment of electroflocculation for classroom in Chemistry. Parameters such as electrode material, current density and temperature direct influence the process efficiency. Due to the process low cost and efficient color removal, the methodology proposed has shown good potential for use in wastewater treatment. In addition, the proposed experiment allows discussion about environmental electrochemistry, introduction to concepts of water contamination by industry and university, and also about different alternatives in wastewater treatment used nowadays. Finally, the very easy operation make possible to easy adapt this experiment for high school and elementary school
