    Abstract: To improve the sludge reduction rate by the combine treatment using alkaline Sodium hydroxide, NaOH) dosage and homogenizer can be affected by a different parameter such as the homogenizer’s rotational speed, NaOH dosage and processing time. In this study, effect of alkaline dosage on aerobic sludge disintegration was investigated in detail. The treatment of sludge with NaOH and thorough homogeneous blending with the homogenizer were carried out to examine efficiency/ effect of the alkaline dosage in the breaking down complex macro molecules structure of the floc into a micro molecular structure which can then be converted to carbon dioxide and water. The results showed that, proper treatment of the waste sludge with 0.25g of the alkaline (NaOH) dosage, homogenization speed of 8000rpm, at 30 minutes processing time, better sludge disintegration was achieved. Sludge reduction rate of 70.9% was achieved. This hands-on report demonstrates the usefulness of the homogenizer blending and mixing in sludge disintegration process
