Denitrification Barriers
Description of the technology Denitrification barriers for agricultural drainage or constructed wetland treatment are one of the newest technologies being investigated for practical edge-of-field nitrate-nitrogen (NO3-N) reduction.

Technology is designed to remove nitrates from wastewater or runoff from agricultural ares.

The principle is a filtration of water with increased nitrate content through a suitable organic substrate. An organic material used serves as a medium, as well as carbon and energy source for growing facultative anaerobic microbial organisms.

Protected by utility pattern.
