Innovative Project In Virginia Changes Lens On Wastewater
Innovative Project In Virginia Changes Lens On Wastewater

In September of 2016, Ted Henifin took the first sip of water purified at a pilot treatment plant developed by HRSD (Hampton Roads Sanitation District). Now, the innovative water treatment program known as SWIFT — Sustainable Water Initiative for Tomorrow — is changing the lens through which communities and government officials view wastewater, drinking water, aquifer replenishment, and even fighting sea level rise.

  • Underground Treatment Of Airport Deicing Fluid
    Underground Treatment Of Airport Deicing Fluid While keeping air flight safe, airports and airlines are also obliged to clean up after themselves and protect nearby streams and water bodies. And due to increasing chemical usage and looming regulations, some airports will need to invest in significant infrastructure upgrades to capture and treat stormwater contaminated with deicing fluid.

    Removal Of PFCs With Activated Carbon

    In recent years, various perflorinated chemicals (PFCs) have come under increasing scrutiny due to their presence in the environment, in animals, and in human blood samples. There are two major classes of PFCs: perfluoroalkyl sulfonates such as perfluorooctanesulfonic acid (PFOS) and long chain perfluoroalkyl carboxylates such as perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA).

    The Importance Of Measuring Total Organic Carbon

    Organic carbon compounds vary greatly. In fact, one of the first lessons in most introductory Organic Chemistry courses explains that the number of possible carbon compounds is virtually infinite due to carbon’s ability to form long, chain-like molecules. While chromatographic methods like gas chromatography (GC) or high-performance liquid chromatography (HPLC) are able to make quantitative determinations for specific compounds, the user must first know which specific compounds to look for.

    How Data And Nature Can Combine To Help Small Wastewater Treatment Plants Address Huge Hauling Costs

    It is no secret that the number of landfills has been steadily decreasing across the United States. As more and more cities adopt ‘zero waste to landfill’ sustainability goals, the number of landfills has shrunk from 6,326 in 1990 to 1,738 in 2015. Decreasing landfills has meant increased waste hauling costs for wastewater treatment plants (WWTPs) as sludge travels farther distances to reach landfills.
