Pôster:

Membrane distillation is an emerging technology for fresh waterproduction. In this work, air gap membrane distillation (AGMD) was used to study theperformance of this process for desalination. The 25000 and 35000 ppm NaCl solutionwere prepared and the experimental tests were carried out during 3 hours. The sampleswere collected to evaluate the permeate flux and rejection. As result, it can be concludedthat AGMD is not very sensitive to feed concentration if compared to others conventionaldesalination processes. High rejection of salt (more than 99.9%) were showed inexperimental results becoming the main advantage of process. The average of permeateflux of distilled water, NaCl 25000 ppm solution and NaCl 35000 ppm were 10.39, 8.81and 7.78 L/m²h, respectively
