Abstract

Aerobic digestion is an endogenous respiration process whereby it will release energy to maintain vital cell function. Using municipal waste as the sample is quite common in this project as it does not create difficulties to maintain the bacteria inside the waste. The main objectives of this project are to reduce the solid content of biodegradable organic sludge and degrading the municipal wastewater. Various methods were used to achieve the objective. However, this project focus on the best method to reduce the organic sludge in shorter time and economical manner besides of the wastewater degradation research using two different types of aerators which are diffuser and SPRINKJET. Parameters used to indicate sludge digestion and wastewater are mass liquor volatile suspended solid (ML VSS), mass liquor suspended solid (MLSS), chemical oxygen demand (COD) and total suspended solid (TSS). SPRINKJET, which is an innovative creation of aerator show a good result. The decrement of MLSS was quite good ( 4 700 mg/L to 6500 mg/L) within 3 days aeration period without neglecting the minimum level of dissolved oxygen. Average of dissolved oxygen recorded was around 7.3 mg/L. Looking at the overall result, there is still room for improvement in order to achieve best results. iii
