Abstract
- Sludge reduction treatment by NaOH/sludge homogenization can be affected by a different parameter such as rotational speed, NaOH dosage and temperature. In this experiment, treatment of sludge with NaOH followed by Homogenizer mixing will be carried out to test the efficiency of NaOH in rapid processing of sludge to disintegrate froc molecules into smaller particles which can then finally be converted to water and carbon dioxide. The results show that the best result of 71.8% sludge reduction rate was obtained when the processing time was 20 minutes, the processing temperature was 70 oC, the alkali dosage was 0.25 g / g MLSS and the homogenizer set at 9000 rpm.
