1.3. Activation of the Biofilter

1.3.2.A The Nitrification Process

We have just seen a few advantages of the nitrification process in the biofilter and will now make some time to look to the different steps in this process:

NH₃ NH₄⁺ NO₂ NO₃^-

As you can see in the chemical reaction free ammonia is always in equilibrium with the ammonium-ion. The equilibrium depends primarily on the pH-value and to a lower extent on temperature.

Balans met aan een kant NH3 en andere NH4; verschuiving naar NH3 bij hoge pH en vice versa
