Construction of a Continuous Flow Eletroflocculation Prototype Supplied By Photovoltaic Energy for Effluents Purification
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2018, Vol 13, Issue 3
Abstract
Effluents production in the most varied industrial sectors has favored environmental degradation, especially when not treated and disposed in soil or water sources, for this reason, this work main objective was to design and construct a electroflocculation prototype under a continuous flow fed by photovoltaic energy to treat effluents in a way to meet the standards established by Resolution No. 430/2011 from CONAMA. The used parameters for the reactor design were conductivity, distance between the electrodes, reactor flow control and reaction time duration based on already performed works as well as on electroflocculation optimization works found in scientific literature. In order to verify the efficiency of the continuous flow electroflocculation reactor for wastewater purification, a residual wastewater effluent test was performed, separating it into two parts so that the effluent could be compared before and after treatment. The chemical analysis revealed a significant reduction of COD (83%) BOD5 (54%) and apparent color (84%). The results showed that the effluent conformed to standards established by CONAMA, thus enabling it to be used in several applications such as iron perchloride production, floors washing, disposal in water bodies, among other applications.
