MAP precipitation from landfill leachate and seawater bittern waste.
The leachates generated at Hong Kong landfill sites contain high strength of ammonium-nitrogen (NH4+-N) over 3,000 mg l(-1) and are generally inhibitive to most biological treatment processes. To remove the NH4+-N from the landfill leachates and also recover the nitrogen as a struvite fertilizer, a lab-scale study was performed to investigate the feasibility of NH4+-N removal and struvite cryst...
متن کاملPretreatment of ammonium removal from landfill leachate by chemical precipitation.
Chemical precipitation is a useful technology to remove ammonium (NH(4)(+)) from landfill leachate. In this paper, the removal of ammonium from landfill leachate was studied. The objective of this study was to investigate optimum pH, optimum molar ratio, and different kinds of chemicals combinations for magnesium ammonium phosphate (MAP) precipitation. Furthermore, the kinetics of MAP formation...
متن کاملChemical Precipitation of Ammonia and Phosphate from Nam Son Landfill Leachate, Hanoi
Leachate from municipal landfills of the city is often contaminated heavily, especially for parameters such as organic components, heavy metals, microorganisms. However, leachate also contains amounts of valuable nutrients (e.g. N, P, K) which can be used for agriculture as fertilizers. Precipitated of N and P in the form of struvite (MgNH4PO4.6H2O) might be applied as a technique for removal a...
متن کاملuranium in municipal solid waste landfill leachate
landfill leachates and leachate sediments were investigated in order to survey the discharge of uranium (u) from municipal solid waste (msw) landfills and municipal solid waste incinerator (mswi) bottom ash landfills. concentrations of u in the leachates were as high as or higher than concentrations of cd, a metal more often discussed when considering the environmental effects of landfill leach...
متن کاملAssessment of Municipal Solid Waste Landfill Leachate Treatment Efficiency by Leachate Pollution Index
Leachate pollution index (LPI) value can be used as a tool to assess the leachate pollution potential of landfill sites particularly at places where there is a high risk of leachate migration and pollution of groundwater and thus can help to take necessary decisions as deem fit. In this paper, leachate treatment efficiency was evaluated on the basis of LPI value of leachate before and after tre...
