<p>This paper presents pilot study results from two projects in which innovative vertical subsurface flow constructed wetland systems are being used to treat municipal solid waste (MSW) landfill leachate.</p>

The SWIFT2D surface-water flow and transport code, which solves the St Venant equations in two dimensions, was coupled with the SEAWAT variable-density ground-water code to represent hydrologic processes in coastal wetlands and adjacent estuaries.

<p>This paper is about the major biological treatment processes for wastewater that include activated sludge processes, aerated lagoons or stabilization ponds, trickling filters or fixed-film reactors, and anaerobic processes.</p>

This paper is about a microcosm test that was conducted to evaluate the role of vetiver grass and different substrates (including coal refuse, fly ash, cinder, soil and gravel) in purifying landfill leachate collected at Likeng landfill site of Guangzhou City ...
