Microsensor determination of multiple microbial processes in an oxygen-based membrane aerated biofilm

Microsensor techniques were used to investigate in situ the simultaneous occurrence of sulfate reduction and nitrogen removal in a membrane aerated biofilm reactor. H2S, O2, pH, ORP, NH4+ and NO3− microsensors were fabricated and used to measure the profiles inside the membrane aerated biofilm. Production and consumption rates of H2S, O2, NH4+ and NO3− were estimated ...

Treatment of synthetic kraft evaporator condensate using thermophilic and mesophilic membrane aerated biofilm reactors

A comparative study on the treatment of synthetic kraft evaporator condensate was conducted using thermophilic (55°C) and mesophilic (30°C) membrane aerated biofilm reactors (MABRs) and sequencing batch reactors (SBRs) for 8 months. Under tested conditions, a chemical oxygen demand (COD) removal efficiency of 80–95% was achieved with both thermophilic and mesophilic MABRs and SBRs. The COD ...

What Is Denitrification?

In Fluence’s membrane aerated biofilm reactor (MABR) technology, simultaneous biological nitrification-denitrification takes place within a single tank due to a bacterial biofilm that forms on its aeration membrane. Nitrates, which are vital to the growth of plants, must be removed during the wastewater treatment process Nitrogen, the most prevalent element in Earth’s atmosphere at ...

What Is Denitrification?

Nitrates, which are vital to the growth of plants, must be removed during the wastewater treatment process Nitrogen, the most prevalent element in Earth’s atmosphere at 78%, can be found in living organisms and decaying matter like humus in soil, as well as in the air we are breathing right now. Nitrogen is considered a vital limiting nutrient, which means that in nature, it typically is ...

Water Treatment Membranes and Their Processes

Filtering out contaminants, even at the nano scale, membranes are a mainstay of water and wastewater treatments In water treatment, membranes are barriers that allow water to pass through but stop unwanted substances from passing through with it. Working much like the cell walls in our bodies, technical membranes filter out salts, impurities, viruses, and other particles from water. A membrane ...
