Abstract
Ammonia is a very soluble gas in water. And the stage of NH3 and NH+4 is affected by pH and temperature.
This studies reports an ammonia removement by air stripping tower in which filled up packing bed (Intalox Saddles). This tower is an apparatus that remove only isolated NH3 by air stripping.
In vitro removement studies have revealed that ammonia removal rates are 97.3, 95.0, 91.5% when each test solution's flow rates are 100, 200, 300ml/min at condition that pH 11.0. It also revealed that ammonia removal rates are more than 90% without regard to test solutions initial conc. at the pH 11.0, flow rate 100ml/min. But when pH is 9.0, it revealed only 18% removal rate. Each result agree with theoretical values of ammonia in water.
Thease studies suggest that our ammonia removement system is effective in liver support and artificial kidney with dialysate regeneration.
