Anoxic

Anoxic conditions, as for anaerobic conditions, indicate the absence of pure oxygen. However, compounds such as nitrate or sulphate can be present under anoxic conditions.

Anoxic conditions, as for anaerobic conditions, indicate the absence of pure oxygen (O2). However, compounds such as nitrate or sulphate (NO3-, SO42-) can be present under anoxic conditions.

Anoxic conditions in wastewater transport and treatment indicate that NO3- or SO42- can be used as oxidation agents when decomposing organic matter.

This can, for example, be in the denitrification process where nitrate (NO3-) is converted into free nitrogen (N2) with the concomitant decomposition of organic matter.
