Manganese oxidation and bacterial diversity on different filter media coatings during the start-up of drinking water biofilters
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 biofilters can vary considerably. The aim of this study was to investigate the effect of different filter media on manganese oxidation and bacterial diversity in biofilters during the start-up. The onset of manganese ...

Competitive mechanism of ammonia, iron and manganese for dissolved oxygen using pilot-scale biofilter at different dissolved oxygen concentrations
In this study, the competitive mechanism of ammonia, iron and manganese for dissolved oxygen (DO) in a biofilter was investigated, and a new start-up method of a biofilter for ammonia, iron and manganese removal was approved, which can effectively shorten the start-up period from 3–4 months to 51 days. The results demonstrated that when DO was sufficient (about 8 mg · L−1), ammonia, iron ...

[Technical Paper] Biomass Evolution in Full-Scale Drinking Water Filters
After nearly two-years of work, we could advance our understanding of ATP measurement in drinking water biofilters. I will describe some of the background and key results from the study below – more information is provided in the Journal AWWA December 2016 article. Background of the Study. Amina Stoddart, a PhD student at our Water Studies lab at Dalhousie, led a project that collected ...
