Nutrient recovery from aquaculture sludge is vital for promoting hydroponic plant growth and achieving near-zero solid waste discharge in aquaponic systems. Modified biological aerated filters (MBAFs) are promising because of the dual capabilities of aquaculture sludge collection and aerobic mineralization. However, the bioconversion kinetics, which is indirectly related to the packed media, need to be improved.

- Nutrient recovery from fish sludge in aquaponics is essential for sustainable economic growth, as current methods fail to reclaim valuable nutrients.
- A two-stage method involving solubilization and phototrophic bioconversion with purple phototrophic bacteria (PPB) is introduced to convert fish sludge into usable nutrients, promoting the growth of both plants and fish.
- Anaerobic treatment outperforms aerobic processes by yielding more soluble nutrients, achieving high biomass production and significant nutrient recovery rates, which can be integrated into a new multiloop aquaponic system for enhanced resource efficiency.
