Feasibility of biological aerated filters (BAFs) for treating landfill leachate
, 2004 Ammonia can be removed from landfill leachate through aerobic biological processes. The biological aerated filter (BAF) combines biological treatment and subsequent biomass separation in one reactor providing a small footprint alternative to ...

Influence of Sediment, Plants, and Microorganisms on Nitrogen Removal in Farmland Drainage Ditches
Agronomy, 2023 The removal of nitrogen from water is a consequence of the synergistic action of plant uptake, sediment sorption, and microbial decomposition. However, there is a lack of long-term experimental studies on the effects of each component in the process of ...
