Oxygen management for optimisation of nitrogen removal in a sequencing batch reactor

, 2003
In today's progressively urbanised society, there is an increasing need for cost-effective, environmentally sound technologies for the removal of nutrients (carbon, phosphorous, nitrogen) from polluted water. Nitrogen removal from wastewater is the focus

Impact of Organic Carbons Addition on the Enrichment Culture of Nitrifying Biofloc from Aquaculture Water: Process, Efficiency, and Microbial Community

Microorganisms
In this study, we developed a rapid and effective method for enriching the culture of nitrifying bioflocs (NBF) from aquacultural brackish water. The self-designed mixotrophic mediums with a single or mixed addition of sodium acetate, sodium citrate, and

Influence of Stubble Mulching on the Nitrification Rate of the Soil

, 1951
The purpose of this paper is to present data comparing the effects of continuous plowing, continuous subsurface tillage, and surface application of straw on the nitrification rate and zone of maximum nitrification in the soil.

Impact of water boundary layer diffusion on the nitrification rate of submerged biofilter elements from a recirculating aquaculture system

, 2012
Total ammonia nitrogen (TAN) removal by microbial nitrification is an essential process in recirculating aquaculture systems (RAS). In order to protect the aquatic environment and fish health, it is important to be able to predict the nitrification rates

Nitrification potential and oxygen limitation in biofilters

, 2000
Nitrification rate is the most important parameter in biofilter design. Research on different aquaculture systems has suggested a wide range of nitrification rates for different types of biofilters.

The short-term effects of nitrification inhibitors on the abundance and expression of ammonia and nitrite oxidizers in a long-term field experiment comparing land management

, 2017
Microcosms were set up to evaluate the effect of nitrification inhibitors (DCD, c-PTiO, and NaClO3) on the abundance and expression of ammonia-oxidizing bacteria (AOB) and archaea (AOA), as well as the nitrite-oxidizing bacteria (NOB) Nitrospira and ...

Response of ammonia-oxidizing archaea to experimental warming in high-N2O-emitting permafrost peatland habitats

Arctic Science
High nitrous oxide (N2O) emissions from bare peat surfaces in permafrost peatlands are mainly produced by denitrification but depend on nitrate (NO3–) supply through nitrification.
