Enabling the Performance of the MBBR Installed to Treat Meat Processing Wastewater

Simultaneous nitrogen and carbon removal from wastewater at different operating conditions in a moving bed biofilm reactor (MBBR): Process modeling and optimization

“…As the sloughing increases, the microbial flocs are formed and the settling of the suspended solids in the settling tank is improved, increasing TSS removal efficiency. In a similar research, treating slaughterhouse in a MBBR, TSS removal efficiency after settling tank was 97% [40]. In another research, treating domestic wastewater, a value of 76.5% was reported for the response [41].…”

“…In this study, biodegradable polymer (PCL) was used as both solid carbon source and biofilm carriers to remove nitrogen from wastewater with a low C/N ratio. In average, 74.6% TN removal efficiency was obtained at HRT of 18.5 h. In another work done by the authors [8], the effects of two types of packing media, polyurethane foam (PUF) and biodegradable polymer polycaprolactone (PCL), at different HRT (14,16,24,40 h) on the removal of organics and nitrogen from wastewater with a low C/N ratio were evaluated. The PUF carriers showed better performance in terms of TOC and ammonium removal efficiency (90 and 65% versus 72% and 56%, respectively).…”
