This study focused on the application of RSM on the Fenton process and the adsorption of vegetal carbon(VC) to obtain the optimal conditions for the minimization of the colored synthetic wastewater. Methylorange (MO) with an azo dye was used as the model organic compound. Fenton processes wereinvestigated to establish the optimal conditions. The Fe2+/H2O2 ratio was studied to establish the majorMO degradation when 100 and 200 mg/L of MO were treated. For the adsorption process, to determinethe optimal conditions, the principal variables studied were the vegetal carbon mass dosage, degradationtime and dye concentration.
DSP-Based Simplified Space-Vector PWM for a Three-Level VSI with Experimental Validation

Multilevel inverters have gained attention in high-power applications due to their numerous advantages in comparison with conventional two-level inverters. In this paper a simplified Space-Vector Modulation (SVM) algorithm for a three-level Neutral-Point Clamped (NPC) inverter is implemented on a Freescale® DSP56F8037. The algorithm is based on a simplification of the space-vector diagram for a three-level inverter so that it can be used with a two-level inverter. Once the simplification has been achieved, calculation of the dwell times and the switching sequences are carried out in the same way as for the two-level SVM method. Details of the hardware design are included. Experimental results are analyzed to validate the performance of the simplified algorithm.
