Nitrate increases the capacity of an aerobic moving-bed biofilm reactor (MBBR) for winery wastewater treatment

Water Science and Technology
We used bench-scale tests and mathematical modeling to explore chemical oxygen demand (COD) removal rates in a moving-bed biofilm reactor (MBBR) for winery wastewater treatment, using either urea or nitrate as a nitrogen source.

IoT Water Quality Monitoring and Control System in Moving Bed Biofilm Reactor to Reduce Total Ammonia Nitrogen [PDF]

Sensors
Traditional aquaculture systems appear challenged by the high levels of total ammoniacal nitrogen (TAN) produced, which can harm aquatic life. As demand for global fish production continues to increase, farmers should adopt recirculating aquaculture ...

Beyond Surface Area: The Role of Carrier Media Structure on Nitrification Performance and Biomass Activity in MBBR Systems Under High Nitrogen Loads. [PDF]

Water Environ Res
Carrier structural configuration, rather than nominal surface area alone, influenced nitrification performance in long‐term autotrophic MBBRs operated under high nitrogen loads. Non‐porous media promoted greater biofilm accumulation and more stable ammonium removal, suggesting that biomass retention capacity plays an important role in sustaining ...

Impact of intermittent feeding on polishing of micropollutants by moving bed biofilm reactors (MBBR)

Journal of Hazardous Materials, 2021
Moving bed biofilm reactors (MBBRs) were placed at two wastewater treatment plants, where they were constantly fed with effluent and intermittently fed with primary wastewater. Each reactor was subjected to different feast/famine periods and flow rates of primary wastewater, thus the different organic and nutrient loads (chemical oxygen demand(COD ...
