A procedural manual for sampling and analyzing sanitary landfill
leachate was designed to guide sanitarians and other public health
officials in monitoring mineral and organic material drainage from
landfill sources. The manual was constructed to allow flexibility of
conducting analytical tests in a field or laboratory environment.
Step-by-step procedures for...
Landfill leachate is a complex wastewater that contains high levels of ammonium (often over 250 ppm) and trace heavy metals (usually under 0.2 ppm). Microalgae have been shown to inexpensively and effectively treat wastewaters containing high loads of organics and nutrients, as well as adsorb metal ions. This thesis focuses...
Several changes appear to be needed in present disposal practices.
Usable materials are discarded in our society in large volume and many of these substances are nonreplaceable minerals. Not only are the minerals themselves lost to society but the energy which produced them is lost as well. Also, the current...
A year-long bench-scale treatability study was performed to assess the feasibility of using an activated sludge sequencing batch reactor (SBR) to treat a mixture of domestic wastewater and landfill leachate. A 50/50 (v/v) of domestic wastewater and landfill leachate was treated in a 1 L SBR operated on a 12...
A year-long, bench-scale treatability study was performed to assess whether an activated sludge sequencing batch reactor could be used to treat an influent stream of 50/50 (v/v) municipal wastewater and landfill leachate to discharge standards established by the Oregon Department of Environmental Quality. One primary obstacle that was exposed during...
Anaerobic ammonium oxidation (anammox) has recently appeared as a promising approach for removing nitrogen from landfill leachates because it requires less oxygen and no organic carbon compared to traditional nitrification-denitrification system, and it produces low sludge volumes, thereby reducing operating and biological sludge disposal costs by over 60%. Anammox bacteria...
Research and public concern of poly and perfluoroalkyl substances (PFASs) as environmental contaminants has increased significantly due to the increasing number of reports of their detection in humans and wildlife. PFASs have a number of commercial applications including surfactants, coatings, polymers, and levelers, which are used on consumer products like...
While fluorochemicals have been detected all over the world and in wastewater
treatment plants, the effect of wastewater effluent on the receiving waters has not been
evaluated. In the first study, the mass flow of fluorochemicals emanating from
wastewater treatment plants along the Glatt River in Switzerland was evaluated. The...
