Optimizing ammonium adsorption on natural zeolite for ...

 · Ion exchange (IE) has been so far limited to treating waters and wastewaters low in solids (TS) and ammonium (NH 4 +). This study provides a new insight into the application of IE for NH 4 + removal from wastewaters with high NH 4 + and TS, using natural zeolite as adsorbent medium.
