It depends on the situation and the way your system is designed but I have had tremendous results removing ammonia using Phytoremediation. I have over the past few years designed a Hydroponic Bioreactor specifically for the removal of nutrients from Wastewater. I use Vetiver grass in my system and it works perfectly with no flocking or sludge wasting required. If you are interested send me an email and I will forward you the information.
