  • Analysis and optimization of ammonia stripping using multi-fluid model

    Ammonia recovery from anaerobic digestion (AD) is a notably beneficial process for removing excess nitrogen, producing low cost fertilizer and enhancing odor abatement. A process was developed for nutrients recovery by integrating a simple and effective stripping process with AD system. To design, optimize and scale up this system, multi-fluid model was developed to simulate flow, mass transfer ...

  • Efficient cleaning of effluent gases from optical fibre production processes using a V-tex scrubber

    In this paper we discuss a unique process technology called the V-tex scrubber. Its design makes it particularly suitable for a wide range of scrubbing and stripping applications, where it can deliver economic and technical advantages for the operator versus conventional packed tower or tray scrubbers, venturi and fluidized bed scrubbers. In cases where there are both particulate and gaseous ...

  • Municipal water treatment plant

    Location: Blueberry, B.C. Owner: Blueberry River Indian Band Description: The poor raw water quality of the wells supplying this community necessitated the installation of a sophisticated 110 m3/d water treatment plant. It incorporates an aeration tower for stripping natural gas and hydrogen sulphide. It is followed by sand filtration for ...

  • Boiler feedwater deaerators

    The thermophysical deaerator is by far the most applied technology when oxygen and carbon dioxide in Boiler Feed Water must be reduced to negligible concentrations Bono ARTES has inherited the experience in the design of Deaerators that started up within the BONO Group in 1959. The Boiler Feed Water, if in equilibrium with the atmosphere, may contain significant levels of corrosive gases, mainly ...

  • Common Treatment Technologies for Nonhalogenated VOCs in Ground Water, Surface Water and Leachate

    It may be necessary to know other subsurface information to provide remediation of VOCs in the ground water. Treatability studies to characterize the biodegradability may be needed for any biodegradation technology. Treatability studies are usually necessary to ensure that the contaminated ground water can be treated effectively at the design flow. A subsurface geologic characterization would be ...

  • Common Treatment Technologies for Fuels in Ground Water, Surface Water, and Leachate

    It may be necessary to know other subsurface information to remediate fuels in ground water. Treatability testing to characterize contaminant biodegradability and nutrient content may be needed for any biodegradation technology. A subsurface geologic characterization would be particularly important to characterize the migration of NAPLs. Recovery tests are usually necessary to design a ...

  • Groundwater remediation pump and treat carberry, Manitoba case study

    Executive Summary Two of four underground gasoline tanks were removed from an old service station located in Carberry, Manitoba a number of years after the facility ceased operating. Two tanks were left on site and were used until 1985, when Manitoba Environment was notified that a domestic well in the vicinity of the abandoned site was contaminated with gasoline. The remaining tanks were ...

  • Food Processing: Odor Control in Edible Oil Processing

    Abstract: The problems with odor around a typical edible oil deodorizer are discussed in detail, and a three-step solution to eliminate these problems is presented. The three steps are a distillate recovery system which recovers most of the fatty acid in the deodorizer vapor discharge as a valuable byproduct, a closed loop barometric cooling water system which keeps the fatladen ...

  • Innovative Ammonia Control case study

    Ammonia has increasingly become more of a regulatory concern. Ammonia emissions into the atmosphere have been linked to the formation of fine particulate matter, while ammonia emissions in wastewater are restricted because of the negative affect the chemical has on rivers, lake, and aquifers. Many sources of biofuels contain ammonia or can create ammonia during processing. The following case ...

  • Scale-up of a Medium Pressure UV System for the Treatment of N-Nitrosodimethylamine (NDMA) and its Advantages Over Low Pressure UV Systems

    Recently there has been considerable concern in California about the detection of N-nitrosodimethylamine (NDMA) in drinking water at levels as high as 900 ppt. NDMA was found to be a carcinogen in animals and assessed as a Class 1 carcinogen. It is currently listed as a priority pollutant on the US EPA National Priorities List. California has set an 'action level' of 20 ppt for NDMA. NDMA is ...

  • Pigeon control…Humane solutions that work

    Who hasn't fed a flock of eager bobbing-headed pigeons at the park? Or chased them into a tree? The honest truth is, we've had a love-hate relationship with our grey-feathered friends since they first landed on a statue or church tower.If you're a home or boat owner, or a facilities manager for a warehouse, airport, park, zoo, government or commercial building, the pest pigeon has undoubtedly ...

  • Plant gains efficiency by replacing vacuum-truck process

    A steel min-mill located in Portage, Ind., that produces and sells hot-rolled steel in the north central United States and Canada. The plant produces about 700,000 tons a year and employs about 400 people. On site is an electric arc furnace melt shop that produces continuous-cast steel slabs and a hot-strip rolling mill for further processing of slabs into rolled coils. The mini-mill's raw ...

  • TB 56: Power plant in thailand uses liqui-cel® membrane contactors to remove co2 from water

    A major power plant in Thailand is using Liqui-Cel® Membrane Contactors to remove carbon dioxide from a DI water system. The system is an expansion project and will be used to feed a high pressure boiler. Liqui-Cel Contactors are being used to lower the CO2 inlet into an Ionpure EDI system. Carbon dioxide adds an ionic load to the EDI system, which can reduce the performance of the system. ...

  • Home, Sweet Wastewater Building

    How can a wastewater treatment plant embedded into a neighborhood not use much landmass and be environmentally friendly and user-friendly all at the same time? One system aims to do all of the above. Why should a wastewater treatment plant always have to look like, well, a wastewater treatment plant?  A visual trip through project files of Aqueonics Inc., based in Greenville, SC, reveals photos ...

  • Common Treatment Technologies for Nonhalogenated VOCs

    Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with nonhalogenated VOC-contaminated soil. Because a presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site, the presumptive remedy approach will accelerate site-specific ...
