Abstract
This study aimed to propose economic evaluation method for installing oil-water separation equipment and suspended solid (SS) recovery equipment into wastewater treatment system to attain energy recycling system in food processing factory using Value Function (VF) and Separative Work Unit (SWU). VF for calculating SWU was determined by the field investigation at the food processing factory, Naoetsu-Yushi Co. Ltd. The results showed the higher SWU of oil-water separation and SS recovery system (the alternative system) than SWU of only oil-water separation system (the current factory). The proposed method could achieve the comparison of different equipment or different conditions for total performance improvement, and support the selection of the alternative equipment or the implement of the surrounding condition.
