The largest percentage of MSW in Malaysia is contributed by the state of Selangor, with a 3,923 tons generated daily. Therefore, the aim of this study is to consider the current condition of the open dumps and sanitary landfills in Selangor from an environmental point of view. Moreover, the local authorities of Malaysia prefer to use landfills that have no liners, biogas capture, and many other...

Classical unlined sanitary landfills are well-known to release large amounts of hazardous and otherwise deleterious chemicals to nearby groundwater and to the air, via leachate ("garbage juice") and landfill gas. It is known that such releases contain a wide variety of potential carcinogens and potentially toxic chemicals that represent a threat to public health. However, little quantitative in...

Process engineering is applied to the design of a new I concept of a municipal incinerator. Each of seven incin· eration process areas are analyzed separately and the equivalent process in the chemical and metallurgical industries examined for proven design features applicable to incineration. Examples of integration of designs for process areas are given. Advantages of this new inciner­ ator c...

BACKGROUND In most developing countries, open defecation is the 'way of life'. This practice is considered as the most serious health and environmental hazard. Prime Minister of India launched the "Swachh Bharat Mission" to accelerate the efforts for achieving universal sanitation coverage and to put focus on sanitation. OBJECTIVE To find the knowledge, attitude and practices of sanitary latr...

This paper discusses the application of artificial intelligence (AI) concepts to the monitoring of a lab-scale Sequencing Batch Reactor (SBR) treating nitrogen-rich wastewater (sanitary landfill leachate). The paper describes the implementation of a fuzzy inferential system to identify the correct switching sequence of the process and discusses the results obtained with six months of uninterrup...

In this study, characterization and anaerobic treatability of leachate from Komurcuoda Sanitary Landfill located on the Asian part of Istanbul were investigated. Time based fluctuations in characteristics of leachate were monitored for an 8 month period. Samples were taken from a 200 m3 holding tank located at the lowest elevation of the landfill. COD concentrations have ranged between 18,800 a...

The biosorption capacity of untreated olive stones (OS) and chemically treated (TOS) to remove COD's landfill leachate was investigated in this study. Characterization the both biosorbents performed using XRD, SEM, FTIR 13C NMR techniques. Leachate taken from Hassi Bounif Sanitary Landfill (HBSL) Oran (Western Algeria). So, (HBL) exhibited a basic pH between 7.83 8.2, high COD level varying 5,2...

background due to burgeoning population, solid waste site selection is one of the most crucial issues in waste management system. regarding the complexity of waste management systems, the convenient solid waste site selection involves considering multiple alternative solutions and assessing different criteria. objectives the current study, aimed to select the fuzzy logic method as one of the mo...
