In this research, the continuously operated laboratory scale Kaldnes (k1) moving bed biofilm reactors (MBBRs) under partial nitrification-denitrification process were used for treatment of synthetic wastewater containing ammonium and glucose. The Anoxic and Aerobic reactors were filled to 40 and 50 %( v/v) to attach and retain biomass with k1 biofilm carriers, respectively. The favorite interna...

Moving bed biofilm reactors (MBBRs) are an effective biotechnology for treating industrial wastewater. Biomass retention on moving bed biofilm reactor (MBBR) carriers (biofilm support materials), allows for the ease-of-operation and high treatment capacity of MBBR systems. Optimization of MBBR systems has largely focused on aspects of carrier design, while little attention has been paid to enha...

A novel process configuration was designed to increase biofilm growth in tertiary moving bed reactors (MBBRs) by providing additional substrate from primary treated wastewater a sidestream reactor under different redox conditions order improve micropollutant removal MBBRs with low availability. This recirculating MBBR operated on pilot scale for 13 months, and systematic seen the biomass concen...

Autotrophic denitrification with biosulfur (ADBIOS) provides a sustainable technological solution for biological nitrogen removal from wastewater driven by biogenic S0, derived biogas desulfurization. In this study, the effect of different biofilm carriers (conventional AnoxK™ 1 and Z-200 pre-defined maximum thickness) on ADBIOS performance microbiomics was investigated in duplicate moving bed-...

The effectiveness of four different electron donors, specifically methanol, ethanol, glycerol, and sulfide (added as Na(2)S), were evaluated in post-denitrifying bench-scale moving bed biofilm reactors (MBBRs). With the requirement for more wastewater treatment plants to reach effluent total nitrogen levels approaching 3 mg/L, alternative electron donors could promote more rapid MBBR startup/ac...

Moving bed biofilm reactors (MBBRs) were placed at two wastewater treatment plants, where they constantly fed with effluent and intermittently primary wastewater. Each reactor was subjected to different feast/famine periods flow rates of wastewater, thus the organic nutrient loads (chemical oxygen demand(COD), ammonium(NH4-N)) resulted in feast-famine conditions applied biomass. In batch experi...

The moving bed biofilm reactor (MBBR) has proven to be an effective system for the treatment of municipal and industrial wastewater. main operating mechanism reactors is growth attached biomass in carriers bioreactor with mixing provided by diffusers aerobic bioreactors or mechanical stirrers anoxic/anaerobic bioreactors. Biofilm formation a complex process affected microbial composition proper...
