Effect of organic loading on rotating biological contactor efficiency.
Organic loading (weight per unit time per volume) is useful for the design of rotating biological contactors (RBC) and for comparison with the other processes such as activated sludge or oxidation ponds. The present study puts emphasis on the significance of this control or design parameter because it allows direct comparison of the RBC system's performance when operated under various circumsta...
متن کاملModified 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 کاملUse of a rotating biological contactor for removal of ammonium from mining effluents
Mine and mill effluents often contain appreciable quantities of ammonia. The discharge of effluents containing ammonia to aquatic systems can have significant environmental effects because ammonia is toxic to fish and other organisms. The Rotating Biological Contactor (RBC) technology has been in use for several years for the treatment of municipal and industrial wastewater. This study evaluate...
متن کاملKinetic modeling of carbon and nutrients removal in an integrated rotating biological contactor-activated sludge system
In this study, kinetics of biological carbon, nitrogen, and phosphorous removal from a synthetic wastewater in an integrated rotating biological contactoractivated sludge system was investigated. The experimental data obtained from varying four significant independent factors viz., hydraulic retention time, chemical oxygen demand for nitrogen to phosphorus ratio, internal recirculation from aer...
متن کاملFGM ROTATING DISC FABRICATE BY Al/Al2O3
Our aim of is to develop a processing method for a rotating disc made of functionally graded materials (FGM), by stacking the slurry, layer by layer in a radial direction. A three-layer functionally graded material of Al/Al2O3 is fabricated with compositions of 10, 20, 30 vol.% Al2O3. The ceramic composition increases from the discs inner (centre) to the outer. The combination of these material...
