  • High Purity Boiler Water Production Using Municipal Wastewater at a Combined Cycle Gas-Fired Generating Station

    The recovery of wastewater for industrial uses presents many challenges for the design and operation of water treatment equipment. Since the term wastewater can be applied to a wide range of water sources from municipal sewage to storm runoff to industrial discharge water, the water characteristics may have great variability. As such, the equipment to treat wastewater must be robust and ...

  • Clean air ensured – Off gas monitoring in mineral wool production – Case Study

    The customer The customer is one of the world’s leading producers of mineral wool – a material that improves the quality of life for millions of people and helps to alleviate environmental problems, such as the greenhouse effect, smog and acid rain. Mineral wool insulation gives us pleasant indoor environments by keeping out the freezing cold. In hot climates, stone wool ...

  • Case study - Vestfjorden Sewage Plant (Veas)

    In Norway’s largest sewage plant, Veas in Oslo, Filtralite* has proven extremely durable as both bio substrate and sludge filtering medium. After 25 years of operation with daily back flushing there is no need for replenishing. A river of sewage of maximum 11 m3 second runs in a 42 kilometre underground tunnel, collecting sewage from Oslo centre to Slemmestad in ...

  • Landfills case study: trash isn’t always dirty

    Most of us don’t put a lot of thought into our trash once it leaves our front door; we may give it a cursory glance as it is hauled away never to be seen again. However, what many of us don’t know is that more and more of our trash—or the byproducts of it, at least—are being used in creative ways to power our daily lives. We never counted on it, but the trash is no longer ...

  • Methane and nitrous oxide emissions from municipal wastewater treatment – results from a long-term study

    Methane and nitrous oxide emissions from a fully covered municipal wastewater treatment plant were measured on-line during 16 months. At the plant under study, nitrous oxide contributed three-quarters to the plant's carbon footprint, while the methane emission was slightly larger than the indirect carbon dioxide emission related to the plant's electricity and natural gas ...

  • NORMs contamination treatment using Ivey-sol technology

    NORMs (naturally occurring radioactive materials) are found almost everywhere, and many natural materials, such as the earth’s crust, contain such radioactive materials. So what happens when oil and gas activities such as petroleum refining and natural gas extraction, disturb such radioactive material? They can alter the natural background radiation — the radiation that we are ...

  • Life cycle assessment study on polishing units for use of treated wastewater in agricultural reuse

    A life cycle assessment (LCA) approach was used in the assessment of environmental impacts of some polishing units for reuse of wastewater treatment plant effluents in agricultural irrigation. These alternative polishing units were assessed: (1) microfiltration and ultraviolet (UV) disinfection, (2) cartridge filter and ultrafiltration (UF), and (3) just UV disinfection. Two different energy ...

  • Biological Removal of Ammonia from Contaminated Air Streams Using Biofiltration System

    ABSTRACT Ammonia is a colorless, toxic, reactive and corrosive gas with a sharp odor. It is irritating to the skin, eyes, nose, throat, and lungs. Ammonia gas occurs in the environment naturally and is emitted by many industries and, therefore, its control is essential. Biofiltration is a new emerging technology that is being used as a control procedure. This study evaluates the use of a ...

  • Upstream Particulate Removal for Rtos on Direct-Fired Osb Dryers – How much is enough?

    Abstract Since 1994 Regenerative Thermal Oxidizers (RTOs) have been applied to direct wood-fired OSB dryers for the purpose of VOC abatement. In early direct wood-fired OSB dryer applications many OSB producers felt that upstream particulate control was not necessary. However, the ash from the combustion of wood waste created a host of new operational problems for the RTO systems. This paper ...

  • From Pilot Studies to Full Scale Plant

    Natural gas is widely used as a primary energy source and is one of the most efficient fuel source. For this reason, more and more gas is utilized exceeding existent production facilities. Oil and gas companies therefore expand there measures and step behind borders finding and exploit new resources. One area of major interest is the Barents Sea, a remote area far from industry and civilisation. ...

  • Odor Eliminators For Roof Top Vents Often Called Stink-Pipes

    Every state, city, and village either has odor ordinances or treats obnoxious odors perceptible beyond property lines as public disturbances/nuisance. All plumbing vent stacks produce odors unless they fitted with a filter. OSHA warns that levels of 300-ppm (H2S) cause the olfactory nerve to lose sensitivity. At first a “rotten egg” odor is detected but on the second or third breath the odor ...


  • One of the largest ipp power plants in the middle east uses membrane desalination for boiler feed water

    The Facility Sidi Krir Unit 3 & 4 Power Plant, developed by InterGen and Edison SpA, is located about 30 kilometers west of Alexandria, Egypt. It is a natural gas fired power plant and at 685 MW generating capacity, is the largest IPP thermal power plant in the Middle East. The plant consists of two power blocks, which share a common membrane based Seawater Desalination system ...

  • Green machine takes new tangent on wastewater reuse

    The idea came to Jason Snydmiller while he was on the island of Borneo. At the time, Snydmiller had learned that the super-major – one of the six largest non-state-owned energy companies – he was under contract to would promptly fine any contractor that left oil in local waters. Although it seemed callous then, the rule was essential, since locals depended on the water for fishing and prawn ...
