Resumo
We worked with a pilot plant RO, with a capacity of 750 l/day, provided with two Hydronautic HR-350 modules, trying to obtain its renovation, through a semi-automatized work allowing the election of a serial/parallel modular configuration and the enlargement of its operative range. A programmable logic controller was necessary to develop the monitoring process and data collecting. A SCADA program was designed, which reads, visualizes and stores measurements. The system was characterized with NaCl solutions, with concentrations between 3-11 g/l by means of the determination of hydraulic permeabilities and reflection coefficient of each membrane, so as the diffusion coefficient due to convective effect of the solvent and its molecular diffusion coefficient.
