Example Sentences

Nick Meier, a farmer in La Porte City, has received grant support in converting 5 acres to wetlands, and has installed a denitrifying bioreactor and cover crops.

Meier seems delighted with his denitrifying bioreactor, as the gizmo is called: It functions properly, it robs him of very little cultivatable space, and it was funded by a state environmental program.

They also are developing water quality strategies that call for installing tens of thousands of denitrifying bioreactors to help reach those targets.

From Time

In the eastern tropical South Pacific, N:P is low because denitrifying bacteria remove nitrogen without also removing phosphorus.
