Abstract :
In order to tackle the problem for remove ammonia from polluted water, clinoptilolite is used for adsorbing the ammonia from wastewater, and biochemical regeneration for ammonia removal was investigated. The results showed that the data were fit to Langmuir isotherms for ammonium ion uptake onto clinoptilolite. For biochemical regeneration experiment, it was stable for the removal of NH3-N by clinoptilolite with removal efficiency over 80% after two months biochemical regeneration using the NaHCO3 regenerant with Na+ concentration of 2000 mg/L and air-water ratio 5:1 at 15degC~26.5degC. The clinoptilolite was suggested as a suitable material for adsorbing ammonia.
