The cost and the carbon dioxide emission in microfiltration (MF) of soy sauce sediment with Agitated Disk Membrane Module (AD Module) were estimated in this note, using the results in the actual soy sauce production line. The cost and the carbon dioxide emission of soy sauce sediment filtration process largely depended upon the operation conditions of AD Module and the concentration ratio of batch filtration. Both more than the agitator revolution of 300rpm and more than 5 times concentration ratio were required economical and environmental friendly MF. This estimation method would be one of the effective tools to adopt new processes of food industry.
