Hello!
I am fairly new to COMSOL, even after reading the manual and configuration book I still can't figure out which physics, I should use, concentrated species or diluted species?
I want to model liquid-liquid membrane contactor in which the wastewater that contains dissolved ammonia will pass through the membrane and will be catch by H2SO4 on the other side. So the outflow of the wastewater will be free from ammonia.
From what I understood from the manual, I should consider this diluted species since the ammonia is dissolved in a wastewater. But I am not convinced myself. Any other opinion or answer?
Thank you!! I really need help for this.
