Geophysical Monitoring of Leachate Injection in Pretreated Waste Landfill

Geophysical Monitoring of Leachate Recirculation at Orchard Hills Landfill

Time behaviour of metals in the leachate of a pretreated solid waste landfill

In the landfills of municipal solid wastes there are a number of constituents which will leach under the influence of infiltrating water. Among the leached constituents there are also trace inorganics which are potentially hazardous to the environment, the most important being the heavy metals. It follows that the waste landfills have a high contamination potential in terms of heavy metals, bec...

Landfill Leachate Monitoring: Applications of Stable Isotopes

The most significant impact of a landfill on the surrounding environment has been consistently identified as arising from the leachate (Farquhar 1989; CAE 1992; Mulvey 1997). Therefore, environmental monitoring programmes for landfills tend to focus on the detection of leachate impacts, particularly any contamination of ground and surface water (Lee and Jones 1991; DCC 1994). Conventional monit...

uranium 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...

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...
