“…In this study, comparing hydraulic retention times (HRTs) of 6, 8, and 10 hours showed that increasing the HRT led to improved efficiency in removing organic matter and nutrients. The removal efficiency of BOD 5 increased from 80.0% at 6 hours HRT to 85.2% at 10 hours HRT, as depicted in Figure (6). Similarly, the COD removal efficiency increased from 76.3% to 81.7% with the corresponding HRTs, shown in Figure (7).…”

“…The high biomass concentration leads to a high volumetric removal rate, making MBBR a more suitable process. This sustainability, along with stable microorganism concentration and high volumetric rate, allows for reduced reactor volume, making MBBR a versatile treatment technology (Bhattacharya, 2022;Ødegaard, 1999). The carrier media in MBBR have less clogging and low head loss due to agitation during aeration.…”

Wastewater treatment faces a growing challenge in removing nutrients and organic matter. This study aimed to evaluate the effectiveness of the moving bed biofilm reactor (MBBR) system in removing nutrients and organic from municipal wastewater. The impact of different carrier filling ratios and hydraulic retention times (HRT) on the removal efficiency was systematically investigated. Moreover, the addition of nanoparticle additives to enhance system performance was evaluated. The optimal conditions for the MBBR system were 30-45% filling ratios and a 10-hour HRT, resulting in maximum removal efficiencies for biological oxygen demand (BOD 5 ), chemical oxygen demand (COD) and ammonia (NH 4 + -N) with a percentage of 85.23%, 81.69%, and 54.45% respectively. Furthermore, adding nanoparticles improved the BOD 5 and COD removal efficiencies by 6.6% and 8.0% respectively, compared to the MBBR system without nanoparticles.
