Method to reduce nitrogen concentration in salt water

Method to reduce nitrogen concentration in salt water

The invention relates to a method for reducing the nitrogen content in salt water having a salinity between 0,5% per weight and 3,5 % per weight, wherein oxygen or an oxygen- containing gas (5, 21) is introduced into a fluid stream (4) to obtain a fluid stream (10) comprising oxygen containing bubbl...

Zusammenfassung:The invention relates to a method for reducing the nitrogen content in salt water having a salinity between 0,5% per weight and 3,5 % per weight, wherein oxygen or an oxygen- containing gas (5, 21) is introduced into a fluid stream (4) to obtain a fluid stream (10) comprising oxygen containing bubbles and wherein said fluid stream (10) comprising said oxygen containing bubbles is introduced into said salt water. Said fluid stream (10) comprising said oxygen containing bubbles is kept at a height below the level (16) of said salt water until it is introduced into said salt water.
