Aerated blast furnace slag filters for enhanced nitrogen and phosphorus removal from small wastewater treatment plants [PDF]
, 2010 Rock filters (RF) are a promising alternative technology for natural wastewater treatment for upgrading WSP effluent. However, the application of RF in the removal of eutrophic nutrients, nitrogen and phosphorus, is very limited.

Microbiological conversions in nitrogen removal
Water Science and Technology, 1998 Nitrogen conversion processes are essential for most wastewater treatment systems. Due to the many possible conversions, and the complexity of analysing the reactions under actual conditions, there is much room for confusion. This review provides an overview of the possible microbiological nitrogen conversions described in literature.

Nitrogen removal in marine environments: recent findings and future research challenges [PDF]
, 2005 Respiratory reduction of nitrate (denitrification) is recognized as the most important process converting biologically available (fixed) nitrogen to N2. In current N cycle models, a major proportion of global marine denitrification (50–70%) is assumed to
