Biological treatment of drinking water to remove manganese (Mn) is becoming more and
more common. However, details as to how the technology works remain poorly understood …

As biological manganese (Mn) removal becomes a more popular water treatment
technology, there is still a large gap in understanding the key mechanisms and range of …

Laboratory biofilters (pilot-scale, 20l and laboratory-scale, 5l) were constructed in order to
model the bioaccumulation of manganese (Mn) under flow conditions similar to those …

Manganese removal is a typical concern in drinking water production. Biofiltration may be
used when treating groundwater sources but the onset of manganese removal in virgin …

The health risks associated with manganese (Mn) in drinking water, and an improved
understanding of Mn accumulation within, and subsequent release from, distribution …

Two pilot-scale trickling filters were constructed and tested for manganese removal from
potable water, using different fractions of silicic gravel as support media (mono-and …

Rapid sand biofiltration (RSBF) is widely used for the removal of contaminants from drinking
water treatment systems. Biofilm microbiomes in the biofilter media play essential roles in …

Soluble manganese (Mn) presents a significant treatment challenge to many water utilities,
causing aesthetic and operational concerns. While application of free chlorine to oxidize Mn …

Manganese removal in drinking water biofilters is facilitated by biological and physico-
chemical processes, but knowledge regarding the relative role of these mechanisms during …

The present work was aimed at evaluating the surface coatings characteristics and
autocatalytic manganese oxidation potentials of two groups of “aged” biofilter media. This …
