Intracep is developing new permeable reactive weir technology to enhance the performance and minimize maintenance requirements. The new technology will extend the service life of the PRW media cartridges, while improving pollutant removal efficiencies. New media specifications are being added to the patent to provide greater control of hydraulic conductivity and target a wider range of contaminants. These new features will compliment those specified in the original general utility patent. The new patent will be filed domestically in 2017 and internationally in 2018.
