Reactor de flujo continuo para la remoción del plomo por electrocoagulación en las aguas del río Coata, Puno-Perú

Abstract

The aim was to design a continuous flow reactor for the experimental removal of lead by electrocoagulation in the waters of the Coata River in Puno, Peru. The reactor design consisted of two flow-through cells that were connected by a pipe channel. The dimensions of the cells were as follows: 17 x 20 x 30 cm. The electrodes measured 23 x 11 cm. and with an additional 1 cm2 . Likewise, the voltage source was 50 Vdc with a current density of 0.8 A. The exit angle for the fluid was 45° where there was a flow of 0.008 L/s with 18.36 minutes of retention time in the first cell. and 34.68 min in the second, respectively. The initial concentration of lead in the untreated water sample was 0.081 mg/L-1. For the first cell, the concentration found was 0.038 mg/L-1, while 0.011 mg/L-1 corresponded to the second cell. The results indicate a removal percentage of 53% and 86% for each cell. It is concluded that the design of the continuous flow rector satisfactorily removed lead concentrations in the waters of the Coata River in Puno, Peru under experimental conditions.
