Field observations of clogging in a landfill leachate collection system

Abstract: The findings from a rare opportunity to exhume, examine, and sample a granular underdrain leachate collection system at a large municipal landfill site are reported. The "clear stone" drainage blanket was constructed from uniform, coarse gravel (with a nominal 50 mm particle size) obtained by crushing dolomitic limestone. After exposure to municipal landfill leachate for 1-4 years, the drainage stone was found to contain a considerable mass and volume of clog and slime materials. These were composed of mineral… Show more

“…A wide variety of sensors has been used for temperature measurements in landfills including thermocouples �e.g., Yeşiller et al �2005� and Koerner and Koerner �2006��, thermistors �e.g., Han et al �2007��, and vibrating wire piezometers �e.g., Fleming et al �1999� andBarone et al �2000��. The writers have deter mined that Type K thermocouples have high resistance to chemi cal environments and are well suited for landfill applications.…”

“…Since these systems may be required to collect and remove leachate for extended periods of time, it is important to design them with an optimum long-term performance life. Fleming et al [20] and Paksy et al [18] conducted lab research on the chemical and biological clogging of drainage layers that might occur during the lifetime of landfill. Research conducted in Canada indicates that tire shreds are more susceptible than gravel to clogging in a saturated drainage area and will not be as effective as drainage layers after a relatively short time.…”

“…Figura VII.7: Esquema del drenaje de un sistema colector de lixiviados: (a) capa continua de drenaje, (b) drenaje francés y tuberías perforadas sobre capa de gravilla (sin escala). Fuente: (Fleming et al 1999) A parte de lo anterior, se debe tener la seguridad de que todo este sistema de recogida y evacuación de lixiviados va a permanecer en el tiempo durante muchos años después de la clausura del vertedero (Fleming et al 2004) ya que los geotextiles, el material granular de drenaje y las perforaciones de las tuberías se pueden obturar por el paso de partículas groseras o lodos y por la acción de la actividad microbiana. Estas obturaciones disminuyen la vida útil de los sistemas de drenaje (Brune et al 1991a).…”
