“…Initially, Reynolds stress was used for modeling water as the continuous phase. The RSM model was reported as an acceptable model with a reasonable computing time and cost [31,32]. After continuous phase development, the air core was modeled by the volume-of-fluid (VOF) model.…”

Biomass particle separation is challenging in the pharmaceutical industry because of the smallness and lightness of such particles. Centrifugation is applied conventionally for batch separation. However, imposing multiple wash steps in order to eliminate culture residues and the high risk of extrinsic contamination hamper batch techniques. In this research, minihydrocyclones were introduced to provide a better solution for the mentioned limitations in continuous processes. Numerical separation of methylotrophic yeast from fermentation broth was carried out in three hydrocyclones with different lengths, and the most efficient one was examined experimentally. Three various feed flow rates and seven feed concentrations were evaluated. The concentration of biomass suspension in the product was raised to 20 %.

“…The centrifugal force required, and consequently the energy required are proportional to the density difference of the constituents involved [60]. The difference in density between oil and water is small, hence, for oil/water separation, the centrifugation process demand a strong centrifugal force and consequently a large amount of energy [61]. A possible approach to lower the energy requirements is by reducing the feed mixture viscosity.…”

“…In this sense, some studies using filtering hydrocyclones have been reported in the literature [ 33 , 34 , 35 , 36 ], in general applied in the mineral sector (solid–liquid separation), and there is little research related to the process of separating water contaminated by oil (liquid–liquid) [ 6 , 7 , 8 , 14 , 30 , 37 , 38 ].…”

Oily Water Separation Process Using Hydrocyclone of Porous Membrane Wall: A Numerical Investigation

et al. 2021

View full text Add to dashboard Cite

This research aims to study the process of separating water contaminated with oil using a hydrocyclone with a porous wall (membrane), containing two tangential inlets and two concentric outlets (concentrate and permeate), at the base of the equipment. For the study, the computational fluid dynamics technique was used in a Eulerian–Eulerian approach to solve the mass and linear momentum conservation equations and the turbulence model. The effects of the concentration polarization layer thickness and membrane rejection coefficient on the permeate flow, hydrodynamic behavior of the fluids inside the hydrocyclone, and equipment performance were evaluated. Results of the velocity, transmembrane pressure and oil concentration profiles along the equipment, and hydrocyclone performance are presented and analyzed. The results confirmed the effect of the membrane rejection coefficient on the equipment performance and the high potential of the hydrocyclone with a porous wall to be used in the oil–water mixture separation.
