  • Solid / gas separation with fabric filters

    A myriad of filter media are utilized today for separation of particulate matter in industrial gas filtration applications. These media range from single use (deposable) to semi-permanent media and include fiber, fabric, ceramic, membrane, metal mesh, and sintered metal media. Semi-permanent media are usually cleanable, either on or off-line, and are primarily intended for long-term (up to ...

  • The Next-Generation Water Filter for the Oil and Gas Industry

    Many segments of the oil and gas production industry need improvements in water filtration over traditional methods. This is true because of the trend toward oil and gas production in tighter, less permeable reservoirs and the greater use of enhanced oil recovery (EOR) techniques, many of which involve injecting water into the oil reservoir. To protect the integrity of such reservoirs, the amount ...

  • Desulfurization performance of biotrickling filter on the removal of flue gas adsorbent produced by dual-alkali flue gas desulfurization process

    A biotrickling filter (BTF) was used to investigate the elimination of flue gas adsorbent containing sulfite, sulfate, and hydrosulfate; it was undertaken to replace the regeneration step of dual-alkali flue gas desulfurization. Sulfate-reducing bacteria (SRB) isolated from landfill leachate were inoculated, and overall desulfurization performance as well as impact resistance was evaluated. The ...

  • Simulating accumulation of biofilms in biotrickling filter

    Accumulations and spatial and dynamic variations of biofilms in the media of a biotrickling filter were simulated using mathematical models for Volatile Organic Compound (VOC) removal. Toluene was selected as the model VOC. Effects of toluene concentration and gas Empty Bed Contact Time (EBCT) on VOC removal were also investigated. Results showed that biofilm thickness increased with increased ...

  • Continuous fibres lead to successfuI filter

    An improved design of wound string filter has doubled contaminant holding capacity and avoided the shedding of small fibres bad into the fluid. Tom Shelley investigates Wound string filters are setting new benchmarks for efficiently catching large amounts of dirt, without risk of introducing stray fibres or other contaminants into the fluid stream being filtered. Initially ...

  • Predicting Diesel Particulate Filter Performance

    The diesel particulate filter (DPF) has been used for many years in the control of diesel particulate matter (DPM)emissions. This technology is characterised by extremely high efficiency and high sensitivity to the application conditions. Research and testing performed by Diesel Controls Ltd. over the past two years has resulted in improved methods for predicting the application based performance ...

  • Developments in string wound filter cartridges

    String wound filter cartridges are the most commonly used filtration media for reducing contamination in water and other liquids. Filtration applications include reverse osmosis and water softening prefiltration, boiler feed water for steam generation, cooling towers and heat exchangers, bottled water, edible oils, oil and gas production, process water for textiles, electroplating and anodizing ...

  • Oxygen Transfer in a Biological Aerated Filter

    The City of San Diego (City) operates the Point Loma Wastewater Treatment Plant (PLWTP) which can normally treat up to 240 million gallons per day (MGD) of chemically enhanced primary treated (CEPT) effluent for ocean disposal. The City wanted to understand the performance capabilities of Biological Aerated Filters (BAFs) in treating CEPT effluent to secondary standards. To this end, the City ...

  • On-Vehicle Exhaust Gas Cooling in a Diesel

    ABSTRACT A diesel emissions control system built and tested on an industrial forklift truck is described. The system utilizes a pleated media type diesel soot filter. The temperature limit of the filter material is well below the temperature of the exhaust gas. Therefore, cooling of the exhaust gas is ...

  • Case study - Monitoring landfill gas

    Infrared absorption Infrared absorption is usually the preferred method for measuring methane and carbon dioxide. Most gases absorb radiation in the infrared region. The wavelength of radiation that is absorbed is determined by the natural vibration frequencies of the molecule. These natural frequencies will depend on several factors. Thus different gas molecules have different natural ...

  • The ecological filter system for treatment of decentralized wastewater

    A vertical flow constructed wetland was combined with a biological aerated filter to develop an ecological filter, and to obtain the optimal operating parameters: The hydraulic loading was 1.55 m3/(m2·d), carbon–nitrogen ratio was 10, and gas–water ratio was 6. The experimental results demonstrated considerable removal efficiency of chemical oxygen demand (COD), ammonia nitrogen ...
