| Summary: | Municipal wastewater or sewage management is crucial as it is one of the major contributors for greenhouse gas (GHG). The biogas yield from biological treatment in sewage treatment plant (STP) contains about 60 % methane. Existing plant in Malaysia are lacking in capturing this by-product. There is a great potential for capturing biogas and combust it to harness energy. Centralised sewage treatment plant (CSTP) is suggested as long term solution for the increasing number of population and environment concern. Optimum location is an important criterion in building new CSTP in order to keep up with rapid development. The main objective of this study is to develop multi-period planning of centralised sewage treatment plant (CSTP) for electricity generation in Iskandar Malaysia. It can be divided into 5 stages; data gathering, problem formulation and superstructure construction, mathematical modelling, General Algebraic Modeling System (GAMS) coding and result analysis. In this study, GIS is used as preliminary step to generate and prepare data for mathematical model. It should plot the sources, substation and new location of CSTP. The software provides the distance between sources of sewage and new plant plus. The plant is able to produce 8 GWh/y of electricity. The model is capable of proposing location of new centralised sewage treatment plant, technology selection and its capacity. |
