Abstract: The use of layered geotextile filters for biological treatment of septic tank effluent prior to ground infiltration was investigated. The goal was to provide secondary treatment and prevent soil clogging by fostering biomass ...

Abstract: A bench-scale study used nonwoven geotextiles as a compact biomass host media to treat wastewater from a combined sewer system. The geotextile coupons were used as baffles and suspended in an aerated reactor. Each baffle ...

Abstract: A quasi-linear elastic constitutive model is proposed to describe the behavior of sand well below failure. It is based on isotropic compression tests and captures the increase in stiffness due to confinement—a unique ...

Abstract: Geotextile‐filter design for the leachate‐collection system in a municipal solid‐waste landfill is quite different from that of a geotextile‐filter design for other conventional geotechnical drainage applications. This is ...

Abstract: The geotechnical properties of ashes from coal‐burning utilities in Pennsylvania, Delaware, and New Jersey are investigated for use in a highway embankment for 1495 near Wilmington, Del. Mechanical and environmental data ...
