Startup and Pilot Testing of MBBR and IFAS Partial Denitrification/Anammox Processes
… methods for a proposed mainstream polishing PdNA MBBR at Hampton Roads Sanitation District's James River Treatment Plant (JRTP). These two MBBRs were started with either virgin carriers or carriers coated with a preliminary biofilm and were fed secondary effluent The MBBRs were dosed with glycerol …

A sponge-based moving bed bioreactor for micropollutant removal from municipal wastewater
… This study investigated a sponge-based MBBR for its effectiveness in the elimination of various micropollutants, including pharmaceuticals and personal care products, steroid hormones, industrial chemicals and pesticides. A moving bed-submerged membrane bioreactor (MB-SMBR) was also …

Evaluating Biological Treatment Systems: (i) Moving Bed Biofilm Reactor versus Biological Aerated Filtration, and (ii) Sulfide-Induced corrosion in Anaerobic Digester Gas Piping
… the performance of a moving bed biofilm reactor (MBBR) versus a biological aerated filtration (BAF) and Section II involved study on causes of deposition in anaerobic digester gas piping. The first section evaluated and compared the performance of a laboratory-scale MBBR and BAF for organic carbon …

Evaluation of Alternative Electron Donors for Denitifying Moving Bed Biofilm Reactors (MBBRs)
Moving bed biofilm reactors (MBBRs) have been used effectively to reach low nutrient levels in northern Europe for nearly 20 years at cold temperatures. A relatively new technology to the US, the MBBR has most typically been used in a post-denitrification configuration with methanol for additional …

Denitrification Under Salinity Stress in Biofilm Reactors
… (FBBR) and in moving bed biofilm reactors (MBBR) were studied, optimizing the process via reactor and biofilm carrier selection, and a salinity inhibition modelling strategy was proposed for the biofilm. Methanol-driven denitrification showed higher tolerance to inorganic ions than …

Comparison of Aeration Strategies for Optimization of Nitrogen Removal in an Adsorption/Bio-oxidation (A/B) Process with an Emphasis on Ammonia vs. NOx (AvN) control
… Feeding effluent from AvN control to an Anammox MBBR improved removal efficiency. Increased soluble COD loading resulted in greater nitrogen removal with strategies operating in an MLE configuration while particulate COD was found to be important for processes where removal was designed to occur …
