WebSep 1, 2024 · Retrofitting conventional denitrification filters into partial denitrification-anammox (PdNA)- or anammox (AnAOB)-based filters will reduce the needs for external carbon addition. The success of AnAOB-based filters depends on anammox growth and retention within such filters. Studies have overlooked the importance of media selection … WebJun 14, 2024 · Interestingly, the synergistic partial-denitrification, anammox, and DNRA (SPDAD) processes were discovered in the system, opening a twilight for the complete …
WebA truly novel added dimension of this work is to incorporate partial denitrification anammox (PdNA) into well-known process configurations and integrating it with enhanced biological phosphorus removal (EBPR) to achieve resource-efficient nitrogen and phosphorous removal. WebApr 13, 2024 · Nitrite accumulation occurred in the B-stage via partial denitrification and partial nitritation (NOB out-selection), depending on operational conditions, and was removed along with ammonia by the tertiary anammox MBBR, with the ability to achieve effluent TIN less than 2 mg/L. Competing Interest Statement
WebPurpose: The purpose of this study was to optimize carbon addition to an anoxic partial denitrification/anammox (AMX) MBBR testing three different carbon sources to maximize TIN removal through the AMX pathway and to minimize effluent TIN. Based on data from the pilot, this tertiary treatment step has shown to be a viable nitrogen polishing option. WebJan 13, 2024 · In Anammox system, it is very meaningful to couple other denitrification processes to reduce the NO 3 − -N produced to NO 2 − -N, provide more electron receptors for Anammox bacteria, and...
