Dynamic α-factor models for fine-bubble- and surface aeration – impact of settleability and implications on N<inf>2</inf>O emission

Qiu, Yuge; Bakos, Vince; Stewart-Campbell, Nyle; Plosz, Benedek (Peer reviewed; Journal article, 2024)

In water resource recovery facilities (WRRF), aeration efficiency and N2O greenhouse gas emission are affected by the variability of the α-factor. Dynamic calibration of α using sensor data represents a significant knowledge ...
Numerical modelling of surface aeration and N<inf>2</inf>O emission in biological water resource recovery

Qiu, Yuge; Ekström, Sara; Valverde-Pérez, Borja; Smets, Barth F.; Climent, Javier; Domingo-Félez, Carlos; Cuenca, Raúl Martínez; Plosz, Benedek (Peer reviewed; Journal article, 2024)

Biokinetic modelling of N2O production and emission has been extensively studied in the past fifteen years. In contrast, the physical-chemical hydrodynamics of activated sludge reactor design and operation, and their impact ...
