Anitha, V. Devaraj and M. N. Zairossani A study was conducted to investigate flux behavior during a cross-flow ultrafiltration (UF) process to concentrate natural rubber skim latex, with in-situ sonication. Tubular polyvinylidene fluoride (PVDF) membranes with 200kD molecular weight cut-off (MWCO) were selected for this study. Experiments were conducted to study the effect of skim latex preservation level with and without sonication at a transmembrane pressure (TMP) of 2 bar. Results showed the permeate flux remained constant with sonication, and a decline in flux was observed without sonication. This study was also able to determine the ideal preservation level where the in-situ sonication improved the permeate flux without affecting the stability of the feed. This ideal preservation becomes the optimum preservation level required for skim latex recovery by ultrafiltration with in-situ sonication. The study showed that the flux with an intermittent ultrasonic application with sonication ratio of 1 was comparable to that for continuous sonication. back
