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 ...

MBBR and IFAS systems [PDF]

, 2019
Even though the moving bed biofilm reactor (MBBR)- and integrated fixed film activated sludge system (IFAS)-processes are designed and used more or less as they were from the beginning (in the 1990s), there have been several advances. This chapter focuses on advances that have been made during the last 10 years in biochemical oxygen demand (BOD)- and ...

Plants synthesize ergothioneine, showing a link to abiotic stress. [PDF]

Plant Biol (Stuttg)
Various plants possess ergothioneine biosynthetic genes and can synthesize this antioxidant, where increased EGT levels under abiotic stress conditions indicate protective functions. Abstract Ergothioneine (EGT) is a sulphur‐containing histidine derivative and a potent antioxidant that exhibits beneficial effects on human health.

Optimizing ciprofloxacin removal through regulations of trophic modes and FNA levels in a moving bed biofilm reactor performing sidestream partial nitritation [PDF]

Water Research X
The performance of partial nitritation (PN)-moving bed biofilm reactor (MBBR) in removal of antibiotics in the sidestream wastewater has not been investigated so far. In this work, the removal of ciprofloxacin was assessed under varying free nitrous acid

Prečišćavanje otpadnih voda primenom MBBR sistema

, 2023
Procesi prečišćavanja otpadnih voda, koji su do sada korišćeni, pokazuju ograničenu mogućnost efikasnog uklanjanja nutrijenata. Ispuštanje netretiranih ili nedovoljno tretiranih otpadnih voda u recipijente, kao što su reke, jezera i mora, može ugroziti akvatične ekosisteme izazivanjem procesa eutrofikacije.

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 ...

Instrumentation, control and automation (ICA) of MBBR plants for nutrient removal in wastewater: ICA of MBBR plants

, 2022
Abstract Cold and dilute wastewater is a major challenge for N-removal at wastewater treatment plants. The moving-bed biofilm reactor process in combination with chemical coagulation/precipitation has proven suitable for nutrient removal under these conditions. Several full-scale plants based on combined pre- and post-denitrification for
