Modified Rotating Biological Contactor
The disposal of domestic wastewater without any treatment into the drainage systems is considered a source of pollution threatening the population. Industrial waste water discharge to the environment is one of the environmental problems which must be controlled. Current mainstream technologies for treatment of domestic wastewater such as activated sludge and tertiary nutrient removal are too co...
متن کاملDenitrification in an anoxic rotating biological contactor under two carbon/nitrogen ratios
CEB Biofilm Group In biological denitrification of wastewater nitrate (NO3 -) or nitrite (NO2 -) are converted into nitrogen gas (N2), in the absence of dissolved oxygen (DO) or under limited DO concentrations. A rotating biological contactor (RBC) is an attached growth bioreactor, that constitutes a very unique and superior alternative technology for carbon oxidation, phosphorus removal, nitri...
متن کاملCharacterization of an autotrophic nitrogen-removing biofilm from a highly loaded lab-scale rotating biological contactor.
In this study, a lab-scale rotating biological contactor (RBC) treating a synthetic NH(4)(+) wastewater devoid of organic carbon and showing high N losses was examined for several important physiological and microbial characteristics. The RBC biofilm removed 89% +/- 5% of the influent N at the highest surface load of approximately 8.3 g of N m(-2) day(-1), with N(2) as the main end product. In ...
متن کاملDynamics of a microbial biofilm in a rotating biological contactor for the treatment of winery effluent
Wastewater from wine-related industries is characterised by high variability in COD and pH. Disposal of these effluents with little or no treatment could lead to heavy financial penalties or pollution of soil and water resources. A pilot-scale rotating biological contactor (RBC) was evaluated for the treatment of winery effluent, with specific focus on the biofilms that formed on the RBC discs....
متن کاملPhysico-Chemical and Biological Treatment of Olive Mill Wastewater by Rotating Biological Contactor (RBC) Reactors
The removal performance of total poly phenols and orthodiphenols (o-diphenols) content in olive mill waste (OMW) was investigated with a three stages cross flow laboratory scale rotating biological contactor (RBC) in the present study. Due to high COD and other pollutant in the original OMW, physico-chemical treatment was effected for COD and other pollutant reduction prior to biological tr...
