Abstract:
In this work, a sweeping gas membrane distillation process has been used for concentration of glucose syrup. The effect of operating variables includ ng feed temperature (45, 55, 65 and 75oC), feed concentration (10, 30, 50 and 150g/l), feed flow rate (200, 400 and 600 ml/min) and sweeping gas flow rate (4, 10 and 16 SCFH) has been investigated. A flat sheet membrane made of PTFE mounted on a plate and frame module made of Plexiglass used for experiments. Results shown that the feed temperature is the most effective parameter on the permeate flux. Increase of concentration led to decrease of flux due to concentration polarization effect. Both feed flow rate and sweeping gas flow rate are affect the permeate flux.
