Estudo da eficiência energética de um sistema de produção de água potável com membrana de microfiltração acionado por energia solar fotovoltaica.

Abstract

This work deals with the study of the energy efficiency of a water system via microfiltration membrane driven by solar photovoltaics. Initially the system characterization was carried out through its operating with variable availability of electric power, being checked your profile operation from the evaluation of the parameters: permeate flow, system recovery and removal of color and turbidity. The evaluation of the system allowed us to characterize the effect of the availability of electric power and operating pressure of the system in the quantity and quality of drinking water produced. From the characterization of the system and using data solarimetric potential region of Campina Grande - PB for the period September/2013 to August/2014, we held the prospect of producing purified water depending on the supply of solar energy available for the specified period . Subsequently, we assessed the functioning of the system operating effectively with solar photovoltaics, which reached an average production of 298,8 L/day, with an average operating pressure of 1,9 kgf/cm²; which corresponds to estimated production predicted from solar energy supply throughout the day. Finally, considering the perspective of producing purified water estimate the number of people served by the operation of the system, which corresponds to an average of 645 people.
