• Here is reported some flocculation properties of lake sediment using a flocculant which is recently developed (herein "flocculant T") for lake sediment. Since the flocculant T contains large amount of free lime with small amount of chlorine and clay mineral, dewatering and decreasing of weight occur effectively. The flocculant T is produced through a cement producing process and the cost is low. This contains few soluble chlorine and sulfuric acid comparing with common flocculant, therefore the dewatered cake is useful for a cement raw material.<BR>As the results, handling efficiency of the filter pressed cake was same as the cake using common flocculants. The content of hazard elements and suspended solid in drainage is negligible small. But drainage shows high pH, therefore neutralization treatment is necessary.
