water pollution prevention Applications

  • Process Design

    Custom water and wastewater engineering, consulting and process design services to prevent air, land, water and environmental pollution. We rework systems as processes change and troubleshoot where necessary to bring systems into compliance. • High purity and process water • Biological nutrient removal • Solids treatment • Toxicity reduction • Industrial treatment • Advanced oxidation and alternative disinfection • Effluent reclamation and reuse • Land application systems • Natural treatment systems • Hydrogen sulfide and odor control • Decentralized treatment systems • Process optimization / operations assistance • Conceptual and strategic water planning

  • Water quality monitoring for environmental industry

    Maintaining the quality of natural waters provides numerous economic benefits by preventing severe deterioration of water resources that would require expensive treatment operations to protect public health and the environment. For instance, monitoring nitrates in surface waters can possibly prevent algal blooms from happening by facilitating the necessary steps to stop pollution sources from discharging nitrogen nutrients into the water system.

  • Geosynthetic Lining for Highway and Civil Applications

    GCL can be used in highway and civil applications such as at airport de-icing facilities used to remove ice build up on the surfaces of planes. During the application process, glycol-based de-icing fluids can leak into local stormwater runoff, potentially causing pollution. CETCO GCLs were found compatible with de-icing fluid (glycol diluted 50/50 with water). GCLs can also be used to line roadway drainage swales for containment and prevent excessive percolation, thereby minimizing potential for groundwater contamination. Another example of using GCL in civil and highway applications is using the liner to contain acid rock and prevent runoff from entering the local water supply.

  • 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.
