Abstract: Hydrogen sulfide (H2S) concentration in landfill gas (LFG) is predominately dependent on the biodegradation of gypsum drywall, a major component of construction and demolition (C&D) debris. This study focuses on the ...

Abstract: Laboratory and pilot tests were conducted to investigate the use of ionizing radiation at an activated sludge wastewater treatment facility with residuals processing. Operational enhancements were investigated with respect ...

Abstract: Laboratory tests using ultraviolet radiation and sonocation energy were found to kinetically enhance an iron-mediated aeration (IMA) process under development to remove chelated metals and radionuclides and associated ...

Abstract: Clogging of leachate collection systems (LCSs) can cause potentially catastrophic failures in landfill operation. The primary cause of clogging is calcium carbonate precipitation, which forms inside the pipe around a nucleus ...
