The purposes of this study were to examine applicability of limestone as a conditioning agent and to determine the optimum conditions for improving dewaterability of digested sludge. The optimum conditions for temp., pH, dosage, particle size, time, and pressure was 30oC, 7, 45 g/l, 100 mesh, 30 min., and 2.66 × 104 N/m2, respectively. On the basis of induced optimum conditions, if adding limestone in digested sludge, it estimated that its specific resistance was 1.43 × 1012 m/kg. Therefore, it seemed that we could utilize limestone as conditioning agent for improving dewaterability of digested sludge.
