  • Geophysical applications to solid waste analysis

    Abstract: Case studies of regional landfills show that electromagnetic geophysical methods can accurately and inexpensively define boundaries and thickness of waste. Degradation of putrescible solid waste generates conductive leachate that can be imaged with a frequency-domain terrain conductivity meter. Terrain conductivity measurements can be modified through a simple algorithm based upon ...

  • Waste management of a microemulsion using elevated temperatures

    Elevated temperatures reduced NAPL-saturated fraction of a treated SPME waste effluent. As temperature increased, aqueous fraction of the separated SPME increased to 0.96 at 90°C. Composite volume samples had optimal separation at 75°C, where >95% of NAPL mass partitioned into the organic phase; while in first pore volume samples, it decreased with increasing temperature after 70°C. Increasing ...

  • Why it’s time to elevate groundwater

    Groundwater stored in the earth’s crust underpins all our lives – the ultimate source of freshwater for billions has become victim of over-extraction and the ultimate sink for pollutants.   For too long, not enough has been done to regulate the use of this precious, on-demand resource and manage disposal of waste. If rates of groundwater depletion have tripled in the past 3 ...

  • Computer simulated versus observed NO2 and SO2 emitted from elevated point source complex

    ISC-AERMOD dispersion model was used to predict air dispersion plumes from an diesel power plant complex. Emissions of NO2 and SO2 from stacks (5 numbers) and a waste oil incinerator were studied to evaluate the pollutant dispersion patterns and the risk of nearby population. Emission source strengths from the individual point sources were also evaluated to determine the sources of significant ...

  • Corrective action at a hazardous waste unit

    Troy Risk performed a RCRA Corrective Action at a closed hazardous waste landfill for a multinational landfill company. The work involved inspection and cleaning of two 85-foot leachate risers. A leachate riser is a stack of 4-foot diameter concrete pipe sections, which provide a passage to the bottom of the hazardous waste landfill. The riser provides access to pumps and electronic leachate ...

  • Resting concerns about wasted energy

    Recently, opponents of wind farm developments, as in those hanging tightly on to the notion of oil is all, have suggested that an increase in wind farm footprints could actually damage the environment by causing dirty air. The phrase is commonly used by sailors to describe the drop in air movement caused by another boats sails catching the breeze. However, this situation is different from wind ...

  • Suldouro waste management facility, Porto, Portugal

    AFS designed, built and installed two gas booster skids with elevated flares for a 2MW power generation plant in Porto. The booster skids supply gas at a constant pressure to two Jenbacher gas engines; the gas is pre-filtered down to 5 micron before leaving the booster skid. The booster control panel is constantly communicating with the Jenbacher control system ensuring that the gas is delivered ...

  • Waste water plant struggles with contamination case study

    A plant in the southwest US commissioning a wastewater plant utilizing proprietary technology for the removal of benzene, toluene, and xylene, or BTX, was experiencing challenges with throughput and elevated operational costs due to the presence of particulate contaminants. The plant takes the wastewater and processes it, removing the BTX prior to being fed to the conventional wastewater plant. ...

  • Why waste management should be on every boardroom agenda

    Waste management isn’t a topic that features high on the average boardroom agenda. But according to the UK’s leading independent provider of waste management solutions, GPT Waste, it should be somewhere on the agenda. In this White Paper, GPT Waste explain that by changing the shape of the decision making process for procuring waste services, any process and manufacturing organisation ...

  • Environmental monitoring of two fish waste ocean disposal sites in Newfoundland and Labrador, Canada

    Sediment contaminant and benthic community surveys were conducted at two fish waste ocean disposal sites in Newfoundland and Labrador, Canada, to assess the environmental impacts of the disposal activities. Despite a dispersive ocean environment, fish wastes accumulated at both sites, initially disturbing the benthic community through organic enrichment and oxygen depletion, but causing no ...

  • Metal releases from a municipal solid waste incineration air pollution control residue mixed with compost

    The influence of 10 wt.% mature compost was tested on the heavy metal leachate emissions from a calcium-rich municipal solid waste incineration air pollution control residue (MSWI APC). Apart from elongated columns (500 and 1250 mm), an otherwise norm compliant European percolation test setup was used. More than 99% of the metals Al, As, Cd, Cr, Cu, Fe and Ni were left in the APC residue after ...

  • Determination of odorous VOCs and the risk of occupational exposure to airborne compounds at the waste water treatment plants

    Concentrations of non methane-VOCs and risk levels of employees’ exposure to VOCs were determined at two Finnish waste water treatment plants. The concentration of hydrogen sulphide (H2S) reached the Finnish OEL (occupational exposure limit). The concentrations of styrene, 1,2-dichloroethane, and toluene were found to be elevated at plant A. 328.4 μg/m3 of styrene and 709.8 μg/m3 toluene was ...

  • Characterization of Iron- and Manganese-cemented Redoximorphic aggregates in wetland soils contaminated with mine wastes

    In wetlands, translocation of Fe and Mn from reducing to oxidizing zones creates localized enrichments and depletions of oxide minerals. In zones of enrichment, oxides cement matrix particles together into aggregates. In this paper, we describe the various Fe- and Mn-cemented features present in the 1 to 2-mm size fraction of mine-waste contaminated wetland soils of the Coeur d'Alene (CDA) River ...
