  • Liquid waste off-gas treatment - Case Study

    Application Biffa Waste Services operate a major waste disposal site at Kilsyth in Scotland where they handle many types of industrial liquid effluent. This can give rise to a range of emissions from both the tank farm and the road tanker deliveries. In addition, significant NO2 and nitric acid fume releases can arise from process upset conditions. ERG provided an emergency NO2 ...

  • Do You Need a Microfiltration or Ultrafiltration Membrane System for Your Plant?

    Determining whether or not an industrial plant needs a microfiltration (MF) and/or ultrafiltration (UF) membrane system isn’t always as straightforward as it seems. While these systems are not essential for every industrial process, when thoughtfully implemented within an intake, process, or waste stream, they can go a long way in improving a facility’s efficiency and/or cutting ...

  • Hutchinson Finds a Quick Reliable Fix to Cavitation Damage

    The Hutchinson Kansas Water Plant gets its water from twenty wells. The water is pumped out of the wells and into a reverse osmosis water treatment center to purify and ensure safe drinking water. At that point, a portion of the water is taken off from the main line, run through the reverse osmosis system and then mixed back with the well water.  This is used to lower the total dissolved ...

  • 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 ...

  • Detailed off-gas measurements for improved modelling of the aeration performance at the WWTP of Eindhoven

    At wastewater treatment plants (WWTPs), the aerobic conversion processes in the bioreactor are driven by the presence of dissolved oxygen (DO). Within these conversion processes, the oxygen transfer is a rate limiting step as well as being the largest energy consumer. Despite this high importance, WWTP models often lack detail on the aeration part. An extensive measurement campaign with ...

At the conclusion of the project Carbonair provided demobilization services including the extraction and disposal of ...

  • Land Treatment

    Introduction Land Treatment is a full-scale bioremediation technology in which contaminated soils, sediments, or sludges are turned over (i.e., tilled) and allowed to interact with the soil and climate at the site. The waste, soil, climate, and biological activity interact dynamically as a system to degrade, transform, and immobilize waste constitutes. Wastes are periodically tilled to aerate the ...

  • Biofiltration systems for the treatment of waste gas from industrial plants

    Bord na Móna Environmental Ltd have considerable experience in the field of biological air filtration (600 installations). Initially, the majority of installations were on Municipal and Industrial Wastewater applications. This was quickly followed by Municipal Solid Waste, an application Bord na Móna jointly developed with its Italian partners Air Clean srl. Since 2000, Bord na Móna have ...

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

    Three technologies that are most commonly used to treat halogenated 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 a ...
