ABSTRACT- As the world's population has grown and become more urban and affluent, waste production has raised drastically. Wastewater reuse has been identified as a way to alleviate water scarcity and improve crop productivity and environmental sustainability. To address the issue, a soil column experiment was carried out in a 3 × 3 factorial randomized block design including three treatments o...

The treatment of municipal landfill's leachate is considered as one of the most significant environmental issues. In this study a laboratory experiment was conducted through land treatment, achieving an efficient and economical method by using Vetiver plant. Moreover, the effects of land treatment of leachate of municipal landfills on the natural reduction of organic and inorganic contaminants ...

The leachate contains dissolved and suspended organic and inorganic, toxic or chemicals pollutants. Leachate can contaminate groundwater, surface water and soil. It can further have detrimental health effects on human being. This study sets out to investigate the effects of land treatment of municipal landfill’s leachate on the natural reduction of nitrogen and phosphorous density existing in t...

Landfill leachate is an important pollution factor resulting from municipal landfill sites. Physical and chemical processes are the better option for pretreatment or full treatment of landfill leachate. This article presents a combination of pre-treatment method (coagulation and adsorption) for leachate collected from municipal solid waste open dumping site. Physico chemical characteristics of ...

The biodegradability of leachate from the land treatment of hydrocarboncontaminated soil was investigated in the laboratory using respirometry and toxicity test­ ing in combination with total petroleum hydrocarbon (TPH) measurements. Soil in land treatment units (LTU) had been contaminated with a diesellike hydrocarbon mixture formerly used as a diluent for crude oil at an oil field in Californ...

Land application of wastewater is a common practice. However, coarse-textured soils and shallow groundwater in Florida present favorable conditions for leaching of wastewater-applied constituents. Our objective in this study was to determine phosphorus (P) and associated cations (Ca, Mg, K, Na) leaching in a Spodosol irrigated with tomato packinghouse wastewater. We packed 12 polyvinyl chloride...

Landfill leachate recirculation is efficient in reducing the leachate quantity handled by a leachate treatment plant. However, after land application of leachate, nitrification and denitrification of the ammoniacal N becomes possible and the greenhouse gas nitrous oxide (N2O) is produced. Lack of information on the effects of leachate recirculation on N2O production led to a field study being c...

The study was aimed at determining the levels of various heavy metals present in the soil and leachate of the Addis Ababa solid waste dumpsite and its potential ecological and public health risk. Six soil and six leachate samples were analyzed from December 15, 2009 to January 10, 2010. The results indicated that amongst the minerals studied, the levels of Aluminum (Al) was the highest and it r...
