Co-inoculating aerobic granular sludge with pre-cultivated aeration-free microalgal-bacterial granular sludge enabled stable SNDPR in a photo-sequencing batch reactor, achieving 99.2% ± 0.7% NH4+-N removal over 100 days.
- Why it matters: Aeration-free MBGS-based SNDPR is promising for sustainable wastewater treatment but has prolonged, unstable start-up that limits practical deployment.
- What they did: A photo-sequencing batch reactor was seeded by co-inoculating SNDPR-capable aerobic granular sludge with pre-cultivated MBGS, then tracked granule properties, cycle performance, mass balance, and microbial communities for 100 days.
- The result: Two distinct MBGS types emerged from the inoculum, with MBGS-S dominated by nitrification and phosphorus removal and MBGS-L dominated by denitrification, while functional microorganisms and key gene abundances persisted and increased to support stable pollutant removal.
