    Centralized wastewater treatment
    (Faculty of Science, Universiti Malaya, 2004) Chamala Muthu; Agamuthu P.
    An assessment was conducted of an integrated wastewater treatment plant (WWTP) in Malaysia. The WWTP has been designed to receive multiple effluents from central utility facilities (CUF) and other neighboring plants with varying wastewater characteristics. Commissioning of the plant was necessary as part of the quality assurance for the plant design specification. Operating units of the WWTP during commissioning are the intake collection, effluent monitoring, primary treatment operation, waste homogenizing and biological unit of processes. The assessment includes the monitoring of average flow rate, total suspended solids (TSS), oil & grease (O&G), pH, temperature, chemical oxygen demand (COD), dissolved oxygen (DO), and mixed liquor suspended solid (MLSS).

    Municipal solid waste management in Malaysia- Possibility of improvement
    (Faculty of Science, Universiti Malaya, 2004) Fauziah S.H.; Simon, C.; Agamuthu P.
    Municipal Solid Waste (MSW) in Malaysia involves the disposal of approximately 98% of the total waste to landfills. Current disposal method of landfilling needs improvements to prolong the landfill life and to minimize the problem of land scarcity. Rapid developments and industrialization in Malaysia necessitate a better and more efficient waste management strategy. The mushrooming of urban areas and rural-urban migration has increased the per capita income due to changes in the consumption patterns that led to increased waste generation. The study involved the compilation of data from relevant municipalities on waste generation in Malaysia. The study also includes waste composition analysis according to income level, to determine the trends of composition produced.

    Sustainable household organic waste management via vermicomposting
    (Faculty of Science, Universiti Malaya, 2009) Fauziah S.H.; Agamuthu P.
    Increasing waste generation in developing countries has alarmed authorities on waste disposal issues. Therefore, various alternatives have been looked into to reduce waste disposed into landfill. Among others are the bioremediation options which may allow the conversion of putrescible wastes into value added products such as compost, biogas and others. This study was aimed to find optimal experimental set-up to conduct small scale vermicomposting suitable for households, since approximately 40-50% (wt) of the waste is putrescible component.

    SWPlan software application for Malaysian municipal solid waste management
    (Faculty of Science, Universiti Malaya, 2007) Fauziah S.H.; Agamuthu P.
    This study was conducted to design an integrated solid waste management system and to determine the best integrated technology in terms of efficiency, cost and performance. SWPlan software was utilized to determine the appropriate waste management approaches including waste reduction, recycling, composting, waste-to-energy conversion, landfill disposal and others.

    Understanding flow of carbon and nitrogen in Malaysian sanitary landfill
    (Faculty of Science, Universiti Malaya, 2013) Venu Mahendra MS.; Mohd Afzanizam M.; Agamuthu P.
    Landfill can be an artificial carbon sink; accumulates and stores carbon-containing chemical compound for an indefinite period. Landfill posed risks of undesired environmental impacts due to the generation of leachate and gases namely carbon dioxide, CO2 and methane, CH4 with trace amounts of nonmethane organic compounds (NMOC) that include air pollutants and volatile organic compounds. Elements were selected based on environmental matrix and importance as raw materials with definite negative effects.
