Human activities add large quantities of nitrogen to the environment, much of which gets washed into streams and rivers. These waterways transport some of that nitrogen to the oceans, but they also ...

An study led by researchers from the Harbin Institute of Technology has unveiled a substantial development in wastewater treatment technology. Published in Engineering, the research introduces an ...

During combustion - one of the most popular industrial processes across all industry sectors - the chemical energy in fuels, such as natural gas, coal, or oil, is converted into heat by oxidization.

After more than a decade of inquiry, a team of scientists has turned the tables on a long-standing controversy to re-establish an old truth about nitrogen mixing in the oceans. After more than a ...

Limnology and Oceanography, Vol. 61, No. 2 (2016), pp. 610-624 (15 pages) To evaluate the relation of isotope fractionation during sedimentary nitrate reduction with sediment reactivity, we measured ...

Some microbes living on sand grains use up all the oxygen around them. Their neighbors, left without oxygen, make the best of it: They use nitrate in the surrounding water for denitrification -- a ...

Denitrification is a microbial respiratory process in which oxidized nitrogen species, primarily nitrate (NO₃⁻) and nitrite (NO₂⁻), are sequentially reduced to gaseous forms such as nitric oxide (NO), ...

SARASOTA COUNTY – Organic carbon, such as sawdust and wood chips, are the keys to improving the effectiveness of a septic system, says Steve Suau, one of three authors of the Community Playbook for ...
