Potencial energético de um sistema de bombeamento de água via membrana de microfiltração.

Abstract

This work deals with the study of the effectiveness of photovoltaic generators drive a via microfiltration water pumping system. The rating system allows to characterize the effect of the availability of electric power and operation of the system pressure to determine the amount of water produced. In the evaluation system used was a cistern of the water supply LABDES (rainwater captured by tile), using a 0.5 hp motor pump power centrifuged, and the variations in operating pressures from 0 to 2 kgf/cm2. Initially the system characterization was performed by means of operation with variable availability of electrical power (conventional Energy), confirmed its working profile from the evaluation parameters: permeate flow, pressure, power and removing color and turbidity. The rating system allowed us to characterize the effect of the availability and the electrical power system operating pressure in the quantity and quality of water produced. Using potential data solarimetric (read-UFCG) of Campina Grande - PB for the period October / 2013 to September / 2014, there was a study of solar energy supply available for the specified period, where it was found that 70.5% of the monthly average irradiation is between 200 and 1400 W / m2. Subsequently, we evaluated the system works effectively operating with photovoltaic solar energy, which reached an average production of 0.36 L / min or 174.4 L / day (mean of Days 1, 2 Days and Days 3) for 8 hours of operation of the system per day, with an average operating pressure of 0.99 kgf / cm² for 3 days.
