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 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...
متن کاملRecovery of Ascorbic Oxidoreductase from Crude Extract with an Aqueous Two-phase System in a Perforated Rotating Disc Contactor
A continuous perforated rotating disc contactor was used to extract the enzyme ascorbic oxidoreductase (E.C.1.10.3.3) from crude extract of Curcubita maxima with an aqueous two-phase system of poly (ethylene glycol) and phosphate salts. The effect of dispersed phase velocity on either protein mass transfer coefficients or separation efficiency at 1, 2 and 3 mL/min was studied. An increase of th...
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...
متن کاملEffect 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...
