Monitoramento do desempenho do sistema de dessalinização da comunidade de Uruçu-PB.

Abstract

Desalination has been one of the supply of drinking water alternativesto benefit the communities diffused in the semiarid regions of Northeast Brazilian. However, monitoring the membrane system is necessary. This work aims monitoring the desalter of Urugu Community - PB, in terms of measured variables, analysis physicalchemical and microbiological. The system monitoring was realized during the period of August 2011 to February 2012. The maintenance monitoring was based on the chemical cleaning system, the time for that maintenance has been indicated by analysis of pressures, flow rates, yields, the salt concentration and the presence of microorganisms. The well water that feeds the membranes system possessesl .842,1 mg/L of dissolved crystal rock salts, which is a prominent feature into the semi-arid aquifer, resulting in Langelier saturation index above zero. The silt and density index and was a major indicator for maintenance and replacement of the system's filters.
