Distribution and Characteristics of Biomass in an Upflow Biological Aerated Filter
… ammonia oxidation second stage) fixed-film biological aerated filter (BAF) was divided in three fractions depending on their attachment strength to the media: detached, easily detachable and strongly attached. VSS measurement showed that the detached and easily detachable fractions accounted …

Performance Evaluation and Yield Determination of a Full-Scale Biological Aerated Filter
Biological aerated filters (BAFs) are an emerging wastewater treatment technology designed for a wide range of municipal and industrial applications. BAFs utilize an inert media, either dense granular or floating, which supports biomass retention in the filter bed. BAFs offer an alternative to …

Using Oligonucleotide Probes to Characterize Nitrification in a Two-Stage Pilot Scale Biological Aerated Filter System
… one, ammonia oxidation stage two) fixed film biological aerated filter (BAF) process was operated on-site at a domestic wastewater treatment plant. Over the study period, hydraulic loadings to the system were varied, generating a range of organic and ammonia loading conditions. Nitrification …

Comparison of Biological Aerated Filter (BAF) performance using two granular sunken media at low organic and hydraulic loadings
Biological treatment forms an integral part of wastewater treatment. Biological aerated filters (BAFs) are submerged attached growth bioreactors which provide biological treatment as well as filtration in a single unit. The packing media used in BAFs plays an important role in the system …

The Influence of Hydraulic Loading Rate on Nitrification Performance in a Two-Stage Biological Aerated Filter Pilot Plant
… stage one, ammonia oxidation stage two) biological aerated filter was operated for 10 months on-site at a domestic wastewater treatment plant. Over the study, the system was operated at different hydraulic loading rates that resulted in a range of applied organic and ammonia mass …

Full-scale operation of a tubular ultrafiltration system in the treatment of oily waste
… addition dissolved air flotation (CA-DAF), biological aerated filter, tubular and rotary ultrafiltration (UF), land application, and constructed wetlands. The primary pollutant of concern was oil/grease (O/G). Separation of the free oil in a single three million-gallon pond was selected as …

Biological Aerated Filters: Oxygen Transfer and Possible Biological Enhancement
A submerged-media biological aerated filter (BAF) has been studied to 1) evaluate oxygen transfer kinetics under conditions without biological growth and 2) determine the influence of biological growth on the rate of oxygen transfer. Collectively, the study evaluates the rates of supply and …
