Intracep filed a new patent application to build upon our existing patent. The new patent application includes the potential for adding an energy source to the permeable reactive weir. The power source may be electrical, mechanical, or thermal. The new application also includes adding various water treatment equipment and sensors to the device to improve performance, monitoring, and automation. Together with the original patented technology, the PRW will be able to handle nearly any scope of work from stormwater treatment to surface water remediation.
