  • Monitoring of VOCs in Porewater

    Monitoring VOCs in porewater in the unsaturated zone is now possible.

    Sorbisense regularly offers new options for using the patented Sorbicell, which is used to monitor surface water, wastewater and groundwater.

    The latest is almost as “ground-breaking” as the SorbiCell itself. Until now it has been difficult, if not impossible, to directly monitor for volatile substances in pore water in the unsaturated zone. But the environmental consultancy firm Ejlskov A/S in Aarhus combined the use of Sorbisense sampling equipment with the proven technology of soil water samplers. With this combination, a practical new method is made available, which allows for monitoring the presence of porewater-dissolved VOCs above the groundwater table. This provides a significantly improved basis to define and determine the leaching risk to the groundwater, and thus allows for better and more cost-efficient decisions to prevent the pollution in reaching the groundwater.

    A simple construction with multiple options

    The application uses SorbiCell VOC combined with suction cells, soil water samplers. When installed correctly, and applied with the correct procedures, the suctions cells extract capillary bound water from the soil matrix. The system demands no other resource than a container that is put under vacuum. The vacuum in the container then ensures a flow through of the Sorbicell over a period of time, fx. 2-3 weeks. The method is highly suitable for monitoring a site over longer periods of time.

  • Industrial Wastewater Treatment

    Processors are continually facing changing environmental regulations, rising costs for wastewater disposal, increasing utility costs, and a growing demand for green products manufactured using sustainable operations. These factors are driving food and beverage processors to pursue on-site wastewater treatment. ADI Systems’ wastewater treatment technology portfolio and experience can provide treatment solutions from pretreatment through to producing effluent of direct-discharge and/or water-reuse quality. Our vast experience in the food and beverage industry includes custom treatment solutions for dairy (milk, cheese, whey, yogurt, and ice cream), soft drink, fruit and vegetable processing (potatoes, corn, tomatoes), snack food, prepared meals, confectionery, and many others.

  • Aircraft De-icing Fluids in Wastewater

    Spent aircraft de-icing fluid is a major pollution con­cern at airports especially in areas with severe winter climates. AnoxKaldnes and Veolia Water Solutions & Technologies can combine our experience in both past and present projects to develop a solution to minimize these concerns, whether it is at a local on-site treatment facility or in conjunction with a local municipal WWTP.
