This research focused on the rice protein recovery from rice starch production wastewater by
ultrafiltration. The effect of operating pressure was performed at different feed pressure from
2 to 10 bar. The suitable condition was chosen based on permeate flux; retention of protein,
carbohydrate, reducing sugar, total dissolved solids (TDS); and purity of protein. The
operating pressure of 6 and 8 bar was selected to conduct the study of batch operation
mode with recycling of retentate. The permeate flux was highest at 6 bar, while the recovery …
