Ammonium Removal from Synthetic Stormwater using Clinoptilolite and Hydroaluminosilicate Columns
Ammonium can enter stormwater control measures (SCMs) with the influent, but is also the intermediate product between organic nitrogen and nitrate, and it is important to retain and treat ammonium within the SCM. In this study the use of aluminosilicate aggregates (CA) and clinoptilolite zeolite (ZT...

| 520 | |a Ammonium can enter stormwater control measures (SCMs) with the influent, but is also the intermediate product between organic nitrogen and nitrate, and it is important to retain and treat ammonium within the SCM. In this study the use of aluminosilicate aggregates (CA) and clinoptilolite zeolite (ZT) was investigated under SCM (column) conditions. ZT was found to have the highest capacity (0.45 mg -N/g ZT vis-a-vis 0.33 mg -N/g CA) at 2.5 mg NH4-N/L. The presence of Ca2+ and K+ was found to reduce the capacity of the media significantly. Increasing the contact time from 10 minutes to 47 minutes enhanced the removal efficiency of the system by 70% for CA and 23% for ZT, respectively. Finally, changes in the influent ammonium concentration resulted in successful removal during concentration increases, but desorption of ammonium for sudden concentration reduction. The use of ZT in media-based SCMs is recommended for ammonium removal. | ||

Ammonium Removal from Synthetic Stormwater using Clinoptilolite and Hydroaluminosilicate Columns |
| abstract |
Ammonium can enter stormwater control measures (SCMs) with the influent, but is also the intermediate product between organic nitrogen and nitrate, and it is important to retain and treat ammonium within the SCM. In this study the use of aluminosilicate aggregates (CA) and clinoptilolite zeolite (ZT) was investigated under SCM (column) conditions. ZT was found to have the highest capacity (0.45 mg -N/g ZT vis-a-vis 0.33 mg -N/g CA) at 2.5 mg NH4-N/L. The presence of Ca2+ and K+ was found to reduce the capacity of the media significantly. Increasing the contact time from 10 minutes to 47 minutes enhanced the removal efficiency of the system by 70% for CA and 23% for ZT, respectively. Finally, changes in the influent ammonium concentration resulted in successful removal during concentration increases, but desorption of ammonium for sudden concentration reduction. The use of ZT in media-based SCMs is recommended for ammonium removal. |
