Avaliação do pré-tratamento de um sistema de dessalinização piloto via osmose inversa.

Abstract

The present work has as objective of to set up and to evaluate a system of pilot desalination, composed with a system of chemical cleaning and an instrument to determine the silt density index. The system was tested with the brackish water of the well of Riacho de Santo Antonio city of the Paraiba state with two chemical pretreatment systems, which were taken as base to evaluate the concentrations of the present components in the water before and after of the process of reverse osmosis. As function of the of water quality, for both systems, acid and Flocon, were obtained potable standard showing Langelier Saruration Index with negatives values.
