The beer used in this research is Anker Bir from PT Delta Djakarta Tbk. The beer main compositions are described in Table 1. There are some peaks detected in the HPLC analysis results which can be seen in Fig. 1. However the size area of the peak is too small to be considered major component in beer. Therefore, it was analyzed only two nutritious content of the beer, maltose and glycerol. The other trace components are not included in the table because it is undetected in the HPLC analysis, thus they can be ignored. A commercial spiral wound non-porous membrane, TW30-1812-75 from DOW Filmtec (Dow Chemical Company) made from polyamide thin-film composite with 0.37 m2 surface area is used. The maximum operation temperature and pressure for this membrane is 45 °C and 10 bar, respectively.
