Abstract
This project plays a vital role which is to remove excess ammonia produced from the Solid Thermophilic Aerobic Reactor (STAR) system using a natural ion exchangers, zeolites. The analyses were carried out in laboratory scale batch reactors and column reactors. The preliminary batch studies showed that zeolites adsorbed ammonia at low concentrations with over 90% removal and the preliminary column study showed that zeolites had steep adsorption curves, which is effectual as resin media. The maximum adsorption capacity for one gram of untreated ZS500RW/H was found to be 35.4 mg NH3-N/gzeolite at 400 mg NH3-N/L. The best performing zeolite was a chabazite (ZS500RW/H). It was also found that one hour heat pretreatment improved the natural adsorption capacity of zeolites best.
