  • Radon Air Stripping of Well Water

    Radon is Frequently Found in Ground Water Radon, symbol Rn, atomic number 86, is a colorless, odorless gas at ambient conditions. It is the heaviest element of the Noble Gas family. As such it is extremely stable and unreactive chemically. But it also is highly radioactive. Its half-life is only 3.8 days. Both Thorium, symbol Th, atomic number 90 and Uranium, symbol U, atomic number 92, have ...

  • CO2 degasification air stripping tower design - Case study

    Background - Water Chemistry Controls the Design A common method to adjust pH of water - typically well water intended for potable use - is to pass the water through a packed tower. Such towers intended to degas the water was also commonly called 'air strippers'. This is because the water is passed down over a bed of 'packing1 as air is blown into the bottom of the tower to pass up and out ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Santa Cruz Meets THM/DBP Challenge with Unique Air Stripping Process - Case Study

    Summary Santa Cruz has successfully demonstrated an innovative way for the City to meet its water quality goals while using process recycled water as part of its supply source. Using the recycled water had caused concern about reliably meeting the U.S. EPA THM/DBP potable water quality standards in its finished water. The City evaluated various aeration treatment processes and chose an E-Z ...

  • 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 ...

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

    Introduction 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 ...

  • 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 ...

  • E-Z Trays selected for Large scale project - Case Study

    A former industrial plant and top Superfund site in Sydney, Australia, had been in operation since the 1930s and contained chlorinated solvent contamination. Because of the size and scope of this project packed towers traditionally would have been the air stripping method of choice, but the client was concerned about the ability of workers having easy access to maintain and clean the units. They ...
