Reynolds Number Calculation Method for Aerobic Biological Porous Packed Reactors

摘要: ABSTRACTThe degree of mixing in aerobic biological porous packed reactors can be quantitatively determined by Reynolds Numbers calculation. The dimensionless parameter accounts for all the inertial and viscous forces fully partially reactors. Two identical were built; each reactor was 14 cm diameter 100 height, providing an empty bed volume 15 L. At approximate organic loading rates (OLRs) 2, 3, 4, 6 kg COD/m 3 .d, numbers partial-bed 40 300, 36 100, 25 500 400 respectively, whilst those full-bed 19 500, 20 11 700 26 400. quantity media therefore had a significant effect on extent filter. Porosity is characteristic resulting from balance between biomass accumulation due to growth loss shear stress. stress arises increased loadings upflow velocity aeration.Keywords : number, mixing, reactors, porosityABSTRAKDarjah pengadukan di dalam reaktor biologi aerobik terpadat berliang boleh ditentukan secara kuantitatif melalui pengiraan Nombor Reynolds.
