Combined Landfill Gas and Leachate Extraction Systems
There is currently a shift of emphasis in the approach to treatment of landfill gas and leachate. Until recently, there have been two disparate schools of thought concerning the collection and disposal of these two by-products of organic waste degradation within the same bio-reactor. The tendency in the past has been to study gas and leachate as separate problems each of which requiring a ...

Raffen landfill site, Cork, Ireland
AFS were awarded a contract to design a gas and leachate collection system, and carry out a 10-week gas pumping trial to evaluate the levels of gas being generated from Raffen Landfill Site. From the pumping trial data, a 200m3/hr HT flare was designed, built and installed. A hydrovane compressor/receiver/dryer package was installed to operate ten pneumatic leachate extraction pumps. Within ...

Biological nitrate removal using waste-derived extracts as sole carbon source
Waste-derived multicomponent extracts were investigated as carbon source for biological nitrate removal. Aerobic and anaerobic sludge from a municipal wastewater treatment plant and leachate from an anaerobic digester treating food waste were studied. Alkaline-heat treatment was used for sludge solubilisation. More than 90% carbon was recovered at pH 10–11. The extracts contain very high ...

A Procedure to assess Contaminated Soil Ecotoxicity
Abstract :Two polluted soil samples were assessed for both acute (Microtox®,Daphnia magna,Thamnocephalus platyurus) and chronic (Pseudokirchneriella subcapitata) toxicity, as well as for genotoxicity (Mutatox®). Bioassays were performed on soil water leachates and on soil solvent extracts to characterize not only the water soluble pollutants but also to evaluate less soluble pollutants or ...

Effects of dissolved organic matter in landfill leachate on photodegradation of environmental endocrine disruptors
The direct and indirect photolysis of Environmental Endocrine Disruptors (EEDs) was investigated with and without Dissolved Organic Matter (DOM) extracted from landfill leachates. The results indicate that degradation of EEDs followed a pseudo-first-order. Photosensitised transformation of EEDs occurred because of the light absorption of DOM under sunlight irradiation while distinctive ...
