  • Air Emissions/Off-Gas Treatment

    A number of technologies have been widely applied for removal of VOCs from off-gas streams. However, the application of these technologies to off-gases from site remediation may be quite limited. Biofiltration has been widely applied for VOC destruction in Europe and Japan, but it has only recently been used in the United States. Catalytic and thermal oxidation are widely used for the destruction ...

    Gas Station Site Dewatering Treatment Florida Carbonair provided a turn-key temporary water treatment system for this project.  A Carbonair field crew mobilized, set up, and trained the clients operators of the system to operate the system. At the conclusion of the project Carbonair provided demobilization services including the extraction and disposal of ...

  • A Four Channel Gas Detector for Wastewater Treatment Plants

    Common hazardous gases found in wastewater treatment plant facilities are hydrogen sulphide, methane, ammonia, carbon monoxide, chlorine and oxygen deficiency. Some facilities may also use ozone, chlorine dioxide or sodium hypochlorite with the chlorine during the sanitization treatment process. Furthermore, sulphur dioxide is often used to de-chlorinate the water once the treatment process is ...

  • Landfill Off-Gas Collection and Treatment Systems

    Purpose This engineering technical letter (ETL) was written to provide guidance for designers to determine appropriate application of Landfill Off-Gas Collection and Treatment Systems, and to properly design and specify these systems. Applicability This ETL applies to all HQUSACE elements, major subordinate commands (MSC) , districts, laboratories, and field ...


  • Wastewater treatment for mining camps/oil and gas camps

    Mining and oil and gas camps operating in remote and environmentally sensitive areas become home to large work forces for extended periods of time. Supplying water for domestic use and treating large volumes of sewage and greywater can be a complex and expensive challenge. Improper wastewater treatment can lead to pollution of the surrounding ecosystems. Many jurisdictions have tightened ...

  • Allweiler pumps in exhaust gas treatment systems in ships

    As environmental regulations become more stringent, waste gas treatment systems are growing in importance. H+H Umwelt- und Industrietechnik GmbH of central Germany has been using Allweiler progressing cavity pumps as a core component of these systems since 2003. The company has been manufacturing catalytic waste gas treatment systems since 1998. Originally they focused on applications in block ...

  • Exhaust gas treatment by an atmospheric pressure microwave plasma

    A microwave process for treating exhaust gases from internal combustion engines is presented. The exhaust gases are ionised by microwave energy at 2.45 GHz and the resultant plasma jet discharges into ambient air and exhaust gas environment. A gas analyser was used to measure the change in exhaust gas composition due to the influence of the plasma. Large decreases in CO2, CO and hydrocarbon ...

  • Greenhouse Gas Inventories and Wastewater Treatment Plants

    ABSTRACT A greenhouse gas inventory identifies the sources and quantities of GHG emissions from a facility or a larger organization. Several best practice standards exist that provide guidance for conducting GHG inventories for industrial facilities like a WWTP. Key considerations in a WWTP GHG inventory will include emissions associated with thefacility’s energy use as well as methane ...

  • Liquid waste off-gas treatment - Case Study

    Application Biffa Waste Services operate a major waste disposal site at Kilsyth in Scotland where they handle many types of industrial liquid effluent. This can give rise to a range of emissions from both the tank farm and the road tanker deliveries. In addition, significant NO2 and nitric acid fume releases can arise from process upset conditions. ERG provided an emergency NO2 ...

  • Case study - Amine tail gas treatment

    COVERING YOUR TAIL GAS The discovery of new shale formations throughout the world and the development of new drilling technologies have increased natural gas production and prompted government agencies to instigate tighter air-pollutioncontrol regulations on processing operations. Unfortunately, meeting environmental regulations is not a profit-generating endeavor. Simply put, the time ...

  • Wastewater Treatment Plant Monitors Greenhouse Gas Emissions

    Globally, little attention is paid to gaseous emissions from wastewater treatment processes. This contrasts greatly with the regulatory monitoring that is applied to the quality of water emissions from such facilities. However, in Helsinki, Finland, a large municipal wastewater treatment facility continuously monitors its emissions of greenhouse gases (GHGs) to help in the city’s efforts to ...

  • Exhaust Gas Treatments for NOx Reduction to Add to Global Warming

    The enforcement of year 2007 stringent emission norm for reduced NOx reduction/oxides of nitrogen gases from the diesel exhaust and the after treatment to reduce them will add to global warming by several fold according to renowned engine combustion kinetics, emission control process expert and inventor -Mr.Srinivasan Gopalakrishnan, Hydrodrive Systems & Controls Pvt. Ltd, India. His invention ...

  • An advanced oxidation process using ionized gas for wastewater treatment

    This study on removing non-degradable materials in wastewater focused primarily on advanced oxidation methods such as ozone, ozone/UV and ozone/H2O2. Wastewater treatment using an ionized gas from plasma has been actively progressing. The ionized gas involves reactive species such as O2+, O2− cluster, O radical and OH radical. Since the ionized gas method has such outstanding characteristics as ...

  • Centralized water and wastewater treatment as a greenhouse gas producer in Finland

    Centralized water and wastewater treatment are key components of modern society but, at the same time, sources of greenhouse gas emissions. In this study, we carried out an assessment of the role of centralized water and wastewater treatment as a greenhouse gas producer in Finland, based on the existing literature and a questionnaire study. The aim of the study was to outline the significance of ...

  • Methodology for the assessment of the greenhouse gas impact of wastewater sludge treatment

    Nitrous oxide (N2O) and methane (CH4) emissions from the wastewater sector represent the second largest source of greenhouse gas (GHG) emissions of the waste sector. A protocol has been developed to measure GHG from sewage sludge treatment. GHG measurements were performed on two industrial sewage sludge composting plants. Measurement campaigns showed GHG emissions range between 0.18 to 3.40 ...
