Rotating biological contactors : a review on main factors affecting performance
Get PDFRotating biological contactors (RBCs)
constitute a very unique and superior alternative
for biodegradable matter and nitrogen removal on
account of their feasibility, simplicity of design and
operation, short start-up, low land area requirement,
low energy consumption, low operating and maintenance
cost and treatment efficiency. The present
review of RBCs focus on parameters that affect
performance like rotational speed, organic and
hydraulic loading rates, retention time, biofilm support
media, staging, temperature, influent wastewater
characteristics, biofilm characteristics, dissolved oxygen
levels, effluent and solids recirculation, stepfeeding
and medium submergence. Some RBCs
scale-up and design considerations, operational problems
and comparison with other wastewater treatment
systems are also reported.Fundação para a Ciência e a Tecnologia (FCT
