What does ammonium nitrogen mean in practice?
The result expresses the total content of ammonia and ammonium ion expressed as nitrogen, and their proportion depends on pH and temperature.
When does it matter?
Is not numerically equal to the concentration of NH4+; an incorrect recalculation changes the assessment of the filter bed load and the nitrification process.
Which solutions are related to it?
The reporting form should be maintained, converted using molar masses and the parameter should be analyzed with pH, nitrites and nitrates.
