High concentration of ammonium (NH 4+) often occurs in groundwater. In this study, the
behavior of NH 4+ catalytic oxidation by a manganese oxide (MnO x) filter was investigated …

Previous studies have shown that ammonium and manganese could be removed from water
by biofilm in a trickling filter. However, it always takes several months to start up a biofilm …

The structure and reactivity of manganese oxides (MnO x) are sensitive to the solution
environment. To explore the effects of dissolved oxygen (DO) on the formation of MnO x in …

Mn-based co-oxides filter media with different Fe/Mn molar ratios were synthesized to
investigate the influence of Fe doping on the catalytic activities for ammonium and …

Although dissolved oxygen (DO) is a key factor for the removal of manganese (Mn) from
aqueous solutions, this study presents an efficient method for Mn removal without any DO …

In recent years, manganese oxides have been widely applied in pollution control, but not
found to be used as NH 3–N adsorbent. In this study, synthetic manganese oxides (MnOs) …

Oxidants are routinely employed to remove manganese from groundwater deeply, but the
conversion pathway of manganese in the process still needed to be explored. In this study …

Removal of manganese in conventional aeration-filtration groundwater treatment plants
(GWTPs) results in the formation of a manganese oxide coating on filter media. The …

Abstract Iron–manganese (Fe–Mn) co-oxide filter media are generally used to treat
ammonium–nitrogen (NH 4+–N)-and manganese (Mn 2+)-contaminated groundwater by …

Two types of filter media in groundwater treatment were conducted for a comparative study
of surface structure and catalytic performance. Natural filter media was adopted from a …
