Freezing and thawing (FT) method has been known as an ef fective technique for removing suspended solid (SS) from suspensions including sewage sludge. In this study, saccharification solution produced from kitchen garbage has been chosen as sample solution, and FT technique has applied to the solution for the removal of SS in the solution. After the FT application for the saccharification solution (SS: 52700 ppm), SS in the solution have been reduced to 1300 ppm. And much clearer supernatant with lower SS content was obtained when FT solution kept at static condition overnight. Consequently, keeping FT solution at static condition overnight for SS sedimentation can remove over 99% of the SS from original kitchen garbage saccharification liquor. Saccharification liquor is easily damaged due to its characteristics. It should be kept frozen till its use as raw material for fermentation. Freezing and thawing offers good option both for SS removal and storage.
