Electro-clarification of clarified juice to minimise evaporator scale

摘要

The removal of silicic acid, calcium phosphate and the sesquioxides is essential for the production of high grade raw sugars. Silicic acid and calcium oxalates are the major compounds causing hard and difficult to remove scale in evaporators. This stu dy investigated the extent to which scale forming ions could be removed from clarified sugarcane juice by electro-coagulation(electro-clarification)using a novel Kaselco reactor fed with DC current).
