In most countries, sanitary landfilling is nowadays the most common way to eliminate municipal solid wastes (MSW). In spite of many advantages, generation of heavily polluted leachates, presenting significant variations in both volumetric flow and chemical composition, constitutes a major drawback. Year after year, the recognition of landfill leachate impact on environment has forced authoritie...

Clean water is becoming one of the most scarce and valuable resources in the twenty first century as its supply is finite and its traditional source is easily polluted by industries and population growth. Existing and traditional wastewater treatment methods are expensive and in most cases are either impractical or unsuitable for smaller communities and certain industries. The Vetiver System wa...

Genotoxic assessment of landfill leachate before and after biological treatment was conducted with two human cell lines (Me45 and NHDF) and Daphnia magna somatic cells. The alkali version of comet assay was used to examine genotoxicity of leachate by DNA strand breaks analysis and its repair dynamics. The leachate samples were collected from Zabrze landfill, situated in the Upper Silesian Indus...

in iraq, waste generation was increased after 2003 war events due to intensepopulation developmentand economic growth. the limitation of designable system for municipal solidwaste (msw) management led toserious problems regarding environment and human health. sanitary landfill in the south of kirkuk is the first kindof effective system for municipal solid waste management in iraq. in the first ...

Co-treatment of landfill leachate and sewage in a traditional wastewater treatment plant (WWTP) is a very common leachate management method in the United States. However, biologically recalcitrant and humic-like leachate organic matters (the major fraction of mature leachate organics) cannot be truly removed by the aerobic biodegradation in WWTPs. Prior to effluent discharge from WWTPs, chlorin...

This study aims to investigate the impact of MSW landfill on the contamination of phthalate esters (PAEs) in nearby environment. Landfill leachate, surface water, groundwater and soil profile samples were collected from a MSW landfill area in Wuhan, China. Contents of 16 PAEs were detected for each sample using gas chromatography method. Results showed that landfill had an obvious effect on the...

In this study, five different experiments were conducted over a period of 170 days to produce biogas by using a variety of mixtures of organic materials and landfill leachate. The aim of this study is to develop a more robust two-stage biogas plant that can accept a wide spectrum of waste products and continue to function without any malfunction. The facility has 5m3 total digester volume, with...

In this study, movement of phosphorus pollution which is leachate to groundwater was investigated in Seri Petalling Landfill. Visual MODFLOW was used to predict subsurface and surface migration of pollution within 10 years. The results of sample analysing of phosphorus has shown its concentration in place of landflill was 2.38 mg/l since the National Water Quality Standard for Malaysia defined ...

The present study is aimed at characterizing the landfill leachate as well as its impact on the surrounding groundwater in Kolkata, India. Landfill leachate has been seasonally characterized from 2012-2014, indicating the landfill site in methanogenic phase with high contamination of organics, nutrients, salts, and heavy metals. Sixty groundwater samples have been analyzed for twenty two physic...
