Ammonia Fertilizer Plant. 23000m3/hr circulation rate. Ammonia 10ppm. Phosphate treatment program

then you have no chance to avoid ammonia, or the production of chloramine from any chlorine oxidant you add.  You might try hydrogen peroxide, although I would not expect great results.  Perhaps you should consider high efficiency water softeners, run cycles of concentration higher than 20, almost no bleed-off water, and have a high system pH, such as > 9 to assist with ammonia rejection from the cooling water.
