Effects of nano-activated carbon on water and gas permeability and hydrogen sulphide removal in compacted kaolin
Source abstract
Abstract
Abstract Many soil amendments have been proposed to exclusively enhance the removal of hydrogen sulphide (H2S; one of the major odorous gas) and reduce water percolation/landfill gas emission in a municipal solid waste landfill. There is no reported data about any single amendment that can simultaneously reduce (i) gas permeability (kg) and saturated water permeability (kw) and (ii) H2S emission. The present study investigated the possible use of nano-activated carbon to amend the physico-chemical properties of kaolin, including kw, kg and H2S adsorption capacity. It was revealed that adding nano-activated carbon of 6% (by mass) could reduce kw and kg by about 60% and more than an order of magnitude, respectively, while increasing the H2S adsorption capacity by more than four times.
