Landfill leachate from municipal solid waste (MSW) landfills is a long-term emission problem, which may last for several hundreds of years. The waste management resulting in this type of problem cannot be considered sustainable. This doctoral thesis focuses on the possibilities for changing leachate management strategies in order to enable a greater degree of sustainability. The first part of t...

Sri Lanka is an island in the Indian Ocean with an area about 65 610 km(2). The population of the country is around 20.2 million. Hazardous disposal of municipal solid waste (MSW) is a major concern particularly in the most urbanized areas of Sri Lanka. However, the current waste management system does not facilitate any waste pre-treatment techniques before final disposal. As a consequence, th...

Pentachlorophenol (PCP) is a persistent organic pollutant (POP) previously used as a timber treatment chemical to prevent sap stain and wood rot. Commonly used in wood treatment industries for the last 50 years, there are now many sites worldwide that are contaminated with PCP. Although persistent, PCP is a mobile contaminant and therefore has a propensity to leach and contaminate surrounding e...

Leachate generation is among the main challenging issues that landfill operators must handle. created when decomposed materials and rainwater pass through waste. carries many harmful pollutants, with high concentrations of BOD, COD, colour, heavy metals, ammoniacal nitrogen (NH3-N), other organic inorganic pollutants. Among them, NH3-N are difficult to be completely eliminated, especially a sin...

a lab-scale sbr equipped with a flat sheet membrane in submerged configuration that is named msbr was used for the treatment of composting leachate. it was fed by biologically treated leachate with overall 70-1360 mg/l chemical oxygen demand (cod). the values of ph, electrical conductivity (ec), and dissolved oxygen (do) were monitored routinely. however, analysis of total cod, soluble cod (sco...

A considerable amount of research has been conducted to demonstrate the development of bioreactor landfills promoted by leachate recirculation [1-10]. The effectiveness of leachate recirculation has been well documented in lysimeter studies [1, 5, 11, 12], test cell studies [2, 13, 14-16] and full-scale studies [17-20]. However, the results from these investigations might not be applied appropr...

(Received: July 21, 2012; Accepted in Revised Form: July 5, 2013) Abstract: The principal concern of this study is to formulate the sub-pollution indices (sub-LPIs) and evaluate the individual and overall leachate pollutant index (LPI) of pilot scale landfill lysimeter at KUET campus, Bangladesh. To these endeavors, leachate samples from collection chamber of landfill lysimeter were sampling an...

In this paper, a statistically-based experimental design with response surface methodology (RSM) was employed to examine the effects of functional conditions on the photoelectrocatalytic oxidation of landfill leachate using a Cu/N co-doped TiO2 (Ti) electrode. The experimental design method was applied to response surface modeling and the optimization of the operational parameters of the photoe...
