| Abstract |
This study examines the efficiency and mechanism of reduction of primary sludge in the primary sedimentation tank with the addition of liquid fertilizer, molasses and acid-base reaction agent. The liquid fertilizer addition ratio varies from 60%, 50% and 40%. Each of the three ratio samples was tested in both 2.0 and 4.0 hours of continuous flow reaction of influent times. The study also measured the change in pH, ORP, TS, VFA and odour in basin before and after the continuous flow reaction in order to analyze the effect of sludge reduction. The result found that the volume of primary sludge decreased significantly with the addition of liquid fertilizer while the most optimal outcome resulted in having the liquid fertilizer addition ratio at 60% and the influent time period of addition of liquid fertilizer in continuous mode at 4 hours. In conclusion, the study found that liquid fertilizer, acid-base reaction agent and VFA have significant effects on the reduction of sludge in primary sedimentation tank. The major component of VFA produced from this experiment was acetic acid. |
