Optimization electrocoagulation process whey acid with phosphorus recovery

The objectives were to optimize the EC process parameters using Taguchi methodology, evaluating the efficiency percentage removal of COD and phosphorus removal. The whey was analyzed in initial and final values de pH, COD and phosphate ions. We used a electrochemical reactor de 2 L, batch type and performed the experimental design optimization, fractional factorial random parameters, the type of L9(3)4, ie four variable at three levels. The results have allowed, working with aluminum anode and cathode iron, 8 hours, voltage 4.67 V, 57.6 recirculation flow Lh-1 and a distance of 1 cm between electrodes, achieve a 63% removal initial COD and a recovery above 83% phosphorus as phosphate.
