Biohydrochemical Enhancement structures for
Streamwater Treatment
Skuyler Herzog, John McCray, and Chris Higgins
Summary: A method to remove stream water contaminants
Description: This invention utilizes manipulations to streambed sediment to
passively drive hyporheic exchange and remove stream water contaminants.
These modular manipulations to sediment permeability and reactivity increase
stream-streambed exchange flows and contaminant removal, respectively.
Biohydrochemical enhancement structures can be designed and built into streams
or artificial channels to efficiently attenuate common pol utants such as nutrients,
metals, pathogen indicators, and organics.
Potential Areas of Application:
 Stormwater Management
 Stream Restoration
 Green Infrastructure / Low Impact Development
 Wastewater Treatment
Main Advantages of this Invention:
 Treats nonpoint source pol ution in-stream
 Passive, low cost, low maintenance
Intel ectual Property Status: US utility patent pending (application #14/715,088)
ID number: 14029
Opportunity: We are seeking an exclusive or non-exclusive licensee for
implementation of this technology.
