  • Case study - Hydraulic slurry emplacement of potassium permanganate and zero valent iron for integrated site remediation

    Site Description: An active electronic manufacturing facility had an on-site TCE handling unit that was active for 10 years. During this time, approximately 1,365 gallons of solvent was released, which created an approximate 16 acre plume in saprolite and bedrock. Contaminants: Primarily TCE at concentrations greater than 200,000 ug/L in the source area with ...

  • Changing the Rules with Mass Detection

    How simplified detectors can provide mass data for every analytical run and speed up method development With access to multiple mass spectrometry systems of varying degrees of sophistication, Davy Guillarme (University of Geneva, Switzerland) wasn’t actively looking for new mass detection solutions. Nevertheless, the Waters ACQUITY QDa mass detector caught his eye. Why? Because it opens a ...

  • What Is Zero Liquid Discharge and How Does It Work?

    Not every industrial facility that produces wastewater will require zero liquid discharge (ZLD). It is usually looked to as a last resort because it can be a complex process that requires a high initial investment. If a facility is located on a site that has severe water scarcity issues and/or astronomical discharge fees, it might be ...

  • Treatment and Disposal of Air Pollution Control Residue

    What is APCr? Thermal waste management using Energy Recovery Facilities (ERFs) is now a well-managed and mature technology that is subject to environmental monitoring by a range of competent international bodies. These ERFs have been established as a means of diverting waste away from landfill disposal and for valorising the material and energy content of the waste. Counter to historic ...

  • Pushing the Limits of Reengineering

    Cutting-edge turbine technology enables more efficient and cleaner power generation. However, the service of advanced gas turbines is challenging—especially when parts need to be replaced. The example of a blade replacement project shows how Sulzer establishes innovative reengineering processes and contributes to a secure energy supply that causes less carbon emission. A Sulzer ...

  • Groundwater remediation with Hydrogen Release Compound

    A substantial manufacturing site in Harlow, Essex, was contaminanated with chlorinated solvents used in degreasingoperations. The main compounds of concern were trichlorethene (TCE), trichlorethane (TCA) carbon tetrachloride (CT) and daughter products. The groundwater was at a depth to water of approximately 1.75m with a river around 600m to the north. Glacial deposits included variable clay ...

  • Effect of Suspended Uncontaminated Sediment on POP Release

    The transport and fate of persistent organic pollutants (POPs) during resuspension events were investigated using a batch mixing technique. This technique allowed for the determination of sorption and desorption kinetics under more realistic mixing conditions than those used in previous investigations. It was demonstrated that sorption follows second-order kinetics that are dependent on both POP ...

  • Applying Proper Dispersion Models for Industrial Accidental Releases

    Even though many industrial facilities have put extra efforts to prevent accidental releases of active and inactive chemicals from processes or storage, accidental releases do happen from time to time due to many reasons. Federal and state regulations require industrial facilities to evaluate and report the impacts of potential accidental releases in terms of distances to toxic endpoint ...

  • Limiting swimming pool outbreaks of cryptosporidiosis – the roles of regulations, staff, patrons and research

    Cryptosporidium is the leading cause of swimming pool outbreaks of gastroenteritis. Transmission occurs through the ingestion of oocysts that are passed in the faeces of an infected person or animal when an accidental faecal release event occurs. Cryptosporidium parasites present specific challenges for infection control as oocysts are highly resistant to chlorine ...
