WebMar 16, 2024 · The study was carried out from May to August of 2024 in an aquaculture pond (65×55×2 m) with a biofilm carrier treatment system. After the biofilm stabilized on the carrier, samples of the biofilm and pond water were collected monthly for microbial analysis by 16S rRNA gene amplicon sequencing and metagenomic sequencing. WebThe evaluation of moving bed biofilm reactor (MBBR) technology described herein comprised part of that effort. The MBBR study was conducted in two phases. In Phase I, the MBBR was evaluated as an adjunct system to the existing ponds. The MBBR was operated to nitrify primary pond effluent for subsequent denitrification in the secondary pond.
