  • Using Air Strippers for Off-gas Treatment - Case Study

    Two pharmaceutical plants in Puerto Rico used large sequencing batch reactor (SBR) systems to treat their wastewater. The primary treatment was an aerobic bio breakdown of the waste. The were forced to change their treament process because of change in treatment regulations. The new regulations required them to treat off-gas that was coming from the SBRs. They were faced with installing a very ...

  • 3.5` LANPAC® proven superior for removing PCE from groundwater in packed tower air strippers

    The problem Dry cleaning fluids have contaminated groundwater supplies in all areas of the United States. One of the most common contaminants is PCE (perchloroethylene or tetrachloroethylene, Cl2C=CCl2). As a suspected carcinogen, PCE must be removed from water to very low levels. The US EPA maximum contaminant level (MCL) for PCE in drinking water is 5 ppb (5 parts per billion, or 5 mg/L). ...

  • KS 1000 compact stripper case study - IEG Technologie GmbH

    VOC-contaminated groundwater is treated in a 2-stage low-profile compact vacuum stripper (CVS). A negative pressure blower applies a vacuum to the treatment chamber. In this chamber a 2-stage stripping reactor is located and the stripping air is directed to the upper tray. The groundwater loops around on the upper tray along designate barriers, while the stripping air is being pulled through the ...

  • SVE and Air Sparging

    Stage 1: The system is a PLC controlled plant equipped with telemetry. Rotary Lobe blowers were used to abstract vapour contaminated with chlorinated hydrocarbons and a similar high pressure blower was used to inject air via solenoid valves individually controlled by the PLC. Extracted vapour was treated in large GRS 2 tonne vapour-phase activated carbon vessels.Stage 2: The system comprised ...


  • Common Treatment Technologies for Nonhalogenated VOCs in Air Emissions/Off-Gases

    Three technologies that are most commonly used to treat nonhalogenated VOCs in air emissions/off-gases are carbon adsorption, catalytic oxidation, and thermal oxidation. Carbon adsorption is a remediation technology in which pollutants are removed from air by physical adsorption onto the carbon grain. Carbon is 'activated' for this purpose by processing the carbon to create porous particles with ...

  • 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 ...

  • Explosion proof high vacuum dual-phase extraction

    This an integrated explosion proof system for the simultaneous extraction of soil vapour and groundwater at potentially explosive concentrations. With a pH of 1 to 2, the groundwater was extremely aggresive and required neutralisation.The system included a double header system (high vacuum and low vacuum) enabling simultaneous extraction from small diameter dual-phase extraction lances and larger ...


  • E-Z Trays at Hard-to-Access Site - Case Study

    E-Z Tray® (U.S. Patent Number 5,518,668) Air Strippers have always been known for their ease of access and cleaning, but for this special site, an old industrial building in Brooklyn, New York, they also had to be installed without the use of any heavy equipment. The site was using a competitor's air stripper on the second floor of an older building and the units had become very ...

  • Treating pharmaceutical wastewater - Case Study

    A pharmaceutical facility in the Caribbean had an existing wastewater treatment process that utilized a sequencing batch reactor (SBR). SBRs use large tanks to collect wastewater, then a number of different options can be employed to treat the water (such as chemicals addition, aeration and mixing). When an SBR aerobically breaks waste down, it can produce a high volume of air that needs to be ...

  • Water Treatment Plant - Birse Construction/Powergen

    A large scale water treatment system rental to Birse Construction as part of the enabling works for site redevelopment.Each separator/settling tank was equipped with a duty and standby pump.The size of activated carbon vessel is unique within the UK with a flow capacity of 200 m3/hr. The vessel contains 20 tonnes of activated carbon and GRS can mobilise several of these at short notice, thus ...


  • Drying of plastic powders - case study

    "Continuous strippers" for polymer powder manufacturing Often in the production process for plastic powders, a solvent such as methanol or alcohol is used, which then has to be completely evaporated again at a later stage. Depending on the consistency of the product, evaporating the solvent is not always particularly easy and the drying process often ¬nishes with residual moisture content in ...

  • Common Treatment Technologies for Halogenated 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 technologies. 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 ...

  • 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 ...

  • Control VOC`s in Refinery Wastewater

    Oil and water do not mix, like many of life’s one-liners this statement is basically true but not the whole story. Many hydrocarbon liquids, particularly aromatics, have significant solubilities in water: Benzene 1800 PPMVToluene 470Ethyl Benzene 150Xylenes 150 Petroleum refineries do not like salts in their feedstock since these corrode and foul process equipment. The first refining step is ...

  • 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 ...
