Adjusting pH + aeration is not as easy as said. Normally you need to adjust pH to 10-11 to blow off the ammonia, then you need to adjust it back. It works well at high concentration, but when the concentration is low, removal by aeration is challenging. I think operation wise the easier way is to use biomass carrier based biological method or zeolite filters.
