POTENCIAL DE APROVEITAMENTO DE ÁGUA DE DESTILADORES CLEVENGER

Abstract

Faced with the water scarcity scenario, the importance of developing actions aimed at water conservation becomes clear. This, in turn, is attributed to actions that favor water savings in springs, public water supply systems and building systems. Among the water conservation actions is the reuse, which makes it possible to reuse, for other purposes, the water already used. In this context, the present work had as general objective to evaluate the potential of use of the cooling water of a Clevenger still in use in the Laboratory of Chemistry of Natural Products of the Instituto Federal Goiano, campus Rio Verde. Therefore, this work was carried out in three main stages: (i) measurement of the volume of distiller's discharge water, (ii) physical-chemical monitoring of the distiller's exit water flow and (iii) proposal of a possible standard installation for reuse of distiller water. The average value of the volume of water discarded was 134.09 L/h. Based on the physical-chemical parameters monitored (temperature, pH, EC, SDT, turbidity and residual chlorine), it is concluded that the distiller's output water can be reused for washing glassware, general cleaning of the building and watering plants. . It was identified that to enable the reuse of water discarded from the distiller studied, it is necessary to install an installation basically composed of two reservoirs (one lower and one upper) with a capacity of 500 liters, and a motor-pump set.
