On the importance of minding one’s Ps and Ts: metamorphic processes and quantitative petrology
2010
This Special Issue comprises a selection of the papers given at a two-day discussion meeting held at the University of Melbourne, Australia in June 2009 to celebrate Roger Powells 60th birthday. At this milestone, it is fitting to review Rogers career to date. He has published 200 scientific papers on topics that range from low- to high-grade metamorphism, from low- to ultrahigh-pressure (UHP) metamor- phism, and from thermodynamics to kinetics. Most of Rogers papers are multi-authored and address important questions in the petrogenesis of metamorphic rocks. Roger is widely known for his work with Tim Holland to develop the most complete internally consistent dataset of thermodynamic proper…
Influence of ferric iron dosing on aerobic granular sludge: granule formation, nutrient removal and microbial community
2021
BACKGROUND: Three lab-scale sequencing batch reactors were used to investigate the effects of Fe3+ on aerobic granular sludge (AGS) formation, nutrient removal, and microbial community. RESULTS: The addition of 6 and 12 mg Fe3+ L−1 could not shorten the granulation time. However, compared to the reactor without Fe3+ addition (average sludge volume index at 30 min (SVI30) 70.8 mL g−1; stable average particle size 548 μm), the addition of 12 mg Fe3+ L−1 helped improve the physical properties of AGS (average SVI30 57.0 mL g−1; stable average particle size 1067 μm). Furthermore, with 12 mg Fe3+ L−1 addition (Fe3+ to PO43−-P molar ratio = 1.33), effective removal of NH4+-N (≤0.5 mg L−1) and PO43…
