in wastewater deamination, it is often necessary to adjust the wastewater's pH value to above 1 1 to achieve good deamination efficiency.

What effect does the pH of wastewater have on membrane deamination?

Wastewater ammonia nitrogen refers to the nitrogen present in water in the form of free ammonia (NH3) and ammonium ions (NH4+). It has a dissociation equilibrium in water.

As the pH value of wastewater increases, the balance will shift to the right, causing the ammonium ion NH4+ to gradually dissociate into free NH3 gas. The dissociation efficiency is shown in the table below.

Therefore, in wastewater deamination, it is often necessary to adjust the wastewater's pH value to above11.5to achieve good deamination efficiency.
