Wandana S, Adlin N, Satanwat P, Pungrasmi W, Kotcharoen W, Takeuchi Y, et al.
Bioresour Technol . 2024 Sep; 413:131496. PMID: 39299346
This study presents a novel approach to sustainable aquaculture by integrating biofloc technology (BFT) with a compact down-flow hanging sponge (DHS) reactor. The integrated BFT-DHS system effectively removed nitrogen compounds...
