Abstract

Electrolysis (ED) is a modern technology for separating pollutants using membranes located in an electric field and has therefore been used in industrial wastewater treatment. The cornerstone of an ED cell is a stack of membranes whose planar plate is composed of cation (CM) and anion (AM) selective membranes. To investigate design requirements such as limiting current density (LCD), current efficiency and membrane resistance by laboratory experimental scale using an ED cell with electrodes, stainless steel 316 [cathode (-) and anode (+)],value of pH equal 6.8 and low voltage supply energy of 24.8 V is installed to remove about 100mg/L for each metal (Iron, Manganese, Nickel, Copper, Zinc, Lead, and Cadmium) ions out of solution of salts. The modified membranes and electrodes to upgrade its durability and conductivity, the recycle flow was 90 and 34 L/hr for concentrate and product, respectively, which are 25 and 9.4 ml/s and with consumed 7 to 11 kWh/m3 for a continuous operation.  For industrial wastewater; the results are obtained a best and encouraging specific with removal efficiency (up to 91.87%) during the 4 hr operating time. The result of removing heavy metal ions was 1.521, 0.96, 0.123, 1.41, 0.94, 0.12 and 0.097 mg/L as initial concentrated and after passing through ED cell became finial concentration 0.23, 0.11, 0.01, 0.22, 0.14, 0.02 and 0.014 with removal efficiency 84.88, 88.54, 91.87, 84.40, 85.11, 83.33 and 85.57% for heavy metal ions under study respectively. The next is being acted on large scale for long operating system.
