The main physical, chemical and biological elements of domestic sewage is more than 99% water and is characterised by volume of flow, physical condition, chemical composition and the bacteria organisms that it contains. (A. Mason,, 2013). Sewage treatment is the process of removing the elements or component of sewage to produce liquid and solid suitable for discharge to the environment or also to be use. Treatment processes can be divided into two treatments, which…show more content…
In consequence, a number of rivers are now unsuitable as sources of drinking water and are affecting further development. Based on the all the information about Sewage Treatment Plant (STP), this study is to make a comparison in Selangor area that how the operation and maintenance of existing STP and how to prevent problems occurs while removing contaminants from wastewater and household that must to be controlled according to the growth of economics and increase in population in Selangor. 1.3 Aim The aim of this study is to compare the operation and maintenance of sewage treatment plant in Selangor Darul Ehsan. 1.4 Scope and Limitation of Study For this study, the scope has been narrowed down the limitations so that the study will be focusing on areas that have been identified, which are:-. I. Sewage Treatment Plant at Taman Desa Aman Puri, Kepong (Extended Aerated) II. Sewage Treatment Plant at TTDI (Oxidation Ditch) III. Sewage Treatment Plant at Taman Megah Mas, Petaling Jaya (Biofiler) IV. Sewage Treatment Plant at Seksyen SS25, Petaling Jaya (Aerated Lagoon) 1.5…show more content…
In order to be an efficient plant, the maintenance of drainage systems, methods are required as strategies through sewer condition and performance (Fenner, 2000). Globally we are faced about 2.4 billion people without access to safe water and adequate sanitation, generally located in developing communities. Perhaps, in developing communities the current large scale of systems for supplying water, wastewater collection and wastewater treatment are not environmentally sustainable because it is difficult to close the cycle of water and nutrients (Ho 2004). The effect of these other measures on disease burden is largely confined to urban areas and is considerably less than that of water supply, sanitation, and hygiene promotion (Cairncross,, 2003). In future 20 years, globally have expected that an additional 2 billion will live in towns and cities, especially in developing countries. Still many of sewage plant in developing countries are not treated that causing a pollution to rivers (Langergraber,
