Development of High Efficiency Partial Nitrification as a First Step of Nitrite Shunt Process using Ammonium-Oxidizing Bacteria (AOB)
… from wastewater using two processes either nitrite shunt or deammonification. In this research, a complete partial nitrification as a first step of the Nitrite Shunt process has been developed under a high nitrogen loading rate (NLR) using a novel strategy to control the DO depending on …

Intensification of Biological Nutrient Removal Processes
… Shortcut nitrogen removal processes; including nitrite shunt, partial nitritation/anammox, and partial denitrification/anammox, as well as low-carbon biological phosphorus removal, were critically-evaluated in this study with an overall objective of intensification of existing infrastructure. At …

Mathematical Modeling of Carbon Removal in the A-Stage Activated Sludge System
… was based on its suitability for a downstream nitrite shunt (i.e. nitritation/denitritation) process. In the downstream process the goal is to eliminate nitrite oxidizing bacteria (NOB) from the reactor while selecting for ammonia oxidizing bacteria (AOB). The results showed that a low SRT (< …

Zeolite Incorporated Materials for Targeted Biomass Retention and Pollutant Removal
… with zeolite-coated carriers, indicating the nitrite-shunt process maybe another application. Zeolite-coated membranes were configured in flow-through membrane-aerated reactors and subject to varying operating lengths, inter-lumen oxygen concentrations, and influent nitrite with mixed results. …

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
… a high particulate COD fraction. A high effluent nitrite accumulation ratio (NAR = NO2-/(NO2-+NO3-)) was seen during this period (46 ± 15%) accompanied by the out-selection of Nitrospira. Feeding effluent from AvN control to an Anammox MBBR improved removal efficiency. Increased soluble COD …
