The Use Of Natural Sorbents For The Treatment Of Industrial Sludge Leachate, Mung Shium Jack Sheih

Dissertations

A sorbent treatment process has been developed which uses natural clay soils and fly ashes as sorbents in the treatment of the hazardous contaminants of potential sludge leachate emanating from industrial landfills. Natural sorbents (i.e., vermiculite, illite, kaolinite, zeolite, acidic and basic fly ashes) were evaluated for the removal of specific cations, anions, and organics from leachates generated from three industrial sludges (i.e., calcium fluoride, metal finishing, and petroleum). The laboratory results indicate that, rather than a single sorbent, a combination of acidic and basic sorbents in a layered system is required to reduce for the measurable contaminants present in …
