Latest Nitrification Stories
A new study reports that anammox, a key process in the nitrogen cycle, is barely present in Narragansett Bay even though it’s a major factor just a little farther out into Rhode Island Sound.
Study examines the disposal of animal waste in large-scale swine production.
New results indicate potential to reduce certain greenhouse gas emissions from oceans to atmosphere.
Excess nitrogen from agricultural and urban lands is contaminating groundwater, streams, lakes and estuaries, where it causes harmful algal blooms and contributes to fish kills.
When fire burns down a forest, nitrate levels go up, and the effects are persistent.
Scientists including researchers from the National Oceanography Centre, Southampton and the University of Essex have discovered that interactions between iron supply, transported through the atmosphere from deserts, and large-scale oceanic circulation control the availability of a crucial nutrient, nitrogen, in the Atlantic.
After more than a decade of inquiry, a Princeton-led team of scientists has turned the tables on a long-standing controversy to re-establish an old truth about nitrogen mixing in the oceans.
By Pedros, P B Onnis-Hayden, A; Tyler, Charles ABSTRACT: The purpose of this study was to investigate the nitrification and nitrogen removal from centrate produced in the dewatering process of anaerobically digested sludge, using a single- unit, single-zone submerged attached-growth bioreactor.
By Dosta, J Gali, A; El-Hadj, T Benabdallah; Mata-Alvarez, J ABSTRACT: An efficient biological treatment to treat reject water from anaerobic digestion of wastewater sludge is the SHARON denitrification process, which takes place in a chemostat reactor, where aerobic/anoxic periods are alternated under specific hydraulic retention time (HRT) and temperature conditions that favor ammonium oxidizers growth and ensure the total washout of nitrite oxidizers, achieving the biological nitrogen...
