A laboratory study of landfill-leachate transport in soils.
Continuous flow experiments were conducted using sand-packed columns to investigate the relative significance of bacterial growth, metal precipitation, and anaerobic gas formation on biologically induced clogging of soils. Natural leachate from a local municipal landfill, amended with acetic acid, was fed to two sand-packed columns operated in upflow mode. Degradation of the influent acetic aci...
متن کاملReview on Landfill Leachate Treatments
Problem Statement: Sanitary landfilling is the most common way to eliminate solid urban wastes. An important problem associated to landfills is the production of leachates. This study is a review of landfill leachate treatments. Approach: The advantages and disadvantages of the various existing leachate treatments discussed under the items: (i) Leachate channeling (combined treatment with domes...
متن کاملApplication of iron nanaoparticles in landfill leachate treatment - case study: Hamadan landfill leachate
This study was performed with the objective of determining the efficiency of iron nanoparticles for reducing chemical oxygen demand (COD), 5-day biological oxygen demand (BOD5), total solids (TS) and color of Hamadan city landfill leachate. Experiments were performed in a batch reactor and the main effective factors of pH, reaction time and concentration of iron nanoparticles were investigated....
متن کاملLandfill Leachate Monitoring: Applications of Stable Isotopes
The most significant impact of a landfill on the surrounding environment has been consistently identified as arising from the leachate (Farquhar 1989; CAE 1992; Mulvey 1997). Therefore, environmental monitoring programmes for landfills tend to focus on the detection of leachate impacts, particularly any contamination of ground and surface water (Lee and Jones 1991; DCC 1994). Conventional monit...
متن کاملAerobic biological treatment of landfill leachate
There is an ongoing need to treat leachates from landfills using approaches that avoid expensive installation and operating costs. Faced with such a problem, Powys County Council (Wales, UK) developed a treatment system based on practical experience. Leachate was re-circulated through aeration towers containing a biofilm supported on plastic media before being polished in reed/filter beds. Inve...
