introduction: sequential batch reactor (sbr) is one of the modified biological treatment systems which is able to remove bod5, nitrogen, and phosphorus from wastewater. the object of this study is to determine the removal efficiency of nitrogen, phosphorus, and heavy metals from municipal wastewater by the advanced sbr system. methods: this descriptive-analytical and cross-sectional study was c...
Biological nitrogen removal in aerobic granular sequencing batch reactors is sensitively affected by process conditions (e.g. dissolved oxygen (DO) concentration, nitrogen loading rate (NLR), influent C/N ratio, among others). The variation of one of these process conditions affects the others, because often they are tightly linked. These interrelationships are a drawback for the experimental a...
SBR as a relevant technology to combine anaerobic digestion and denitrification in a single reactor.
Two laboratory-scale sequencing batch reactors were used to study biological treatment of carbon and nitrogen in a new combined anaerobic-aerobic system. Piggery wastewater was used as a model effluent. The anaerobic reactor, fed with raw wastewater and nitrite/nitrate recycling from the aerobic reactor, carried out denitrification and anaerobic digestion of organic carbon. In the aerobic react...
An integrated approach for efficient biomethane production from solid bio-wastes in a compact system
BACKGROUND Solid bio-wastes (or organic residues) are worldwide produced in high amount and increasingly considered bioenergy containers rather than waste products. A complete bioprocess from recalcitrant solid wastes to methane (SW2M) via anaerobic digestion (AD) is believed to be a sustainable way to utilize solid bio-wastes. However, the complex and recalcitrance of these organic solids make...

AAqua-Aerobic Systems (AAS), in partnership with the Colorado School of Mines (CSM), has completed the successful startup of a sequencing batch reactor-membrane bioreactor (SBR-MBR). The package system treats domestic wastewater generated by a 400-apartment, student and faculty housing-complex located on the CSM campus in Golden, CO. This success is rooted in a 15-year development program that ...
This study investigated the bioreactor performance, production of extracellular polymeric substance (EPS), and microbial activity a granulated sequencing batch reactor (SBR) by increasing graphene oxide nanoparticle (GO NP) concentration stepwise. The GO NPs reduced removal chemical oxygen demand (COD), ammonia, phosphorus, whereas nitrite nitrate contents effluent were kept stable during exper...
