| Summary: | 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 (MLVSS), 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 (4700 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
