Normalização de um sistema de dessalinização piloto utilizando um módulo de gerência distribuída com capacidade de monitoração remota.

Abstract

The majority of the desalination systems via reverse osmosis installed in the brazilian northeast comes facing problems as the lack of operation qualification, monitoring and maintenance. As consequence of this, the membranes useful life of the equipment comes decrease due the fouling formation during the desalination process. In this direction, the present work aims at to introduce in developed software (SISMODES), a set of equations of the reverse osmosis process to carry through the pilot desalination system (SDP) normalization from the measures variable that are sent to the management server and to get, from the normalized parameters, a diagnosis of the incrustation type that is occurring. For this, the SDP possess a set sensors that send the values of the measures variable, through the embarked computer, for the serving machine data base through the telephonic line. The SGBD (Data base System Management) used was the SGBD Interbase 6.0 of the Borland that is free softwares and the used operational system was the Linux Mandrake 8.1. All the system web was implemented in Java language and the used server to show dynamic pages HTML was the server tomcat of the Jakarta project. All the project interface was developed in JSP. Besides making possible the remote management of the pilot desalination system (SDP), developed software makes a SDP normalization in real time, allowing the graphs exhibition that show the measures variable behavior, as well as, of the normalized parameters, in function of the SDP running time. The software also is capable to show a incrustation diagnosis in function of the normalized parameters. Besides indicating the type and the localization of the system incrustation, SISMODES indicates a series of experimental tools that can be used to confirm the diagnosis, as well as points the corrective actions that must be taken by the operators/technician to finish or to inhibit the incrustation.
