A high-efficiency mini-hydrocyclone for microplastic
The modification of the underflow orifice diameter increased the total efficiency and underflow-to-throughput ratio by 9 % and 125 %, respectively, and reduced the Euler number by 16 %. Design of an optimized hydrocyclone for high efficiency and low energy consumption. Ind. Eng. Chem. Res., 59 (37) (2020), pp. 16437-16449, In addition, the HA hydrocyclone showed an overall separation efficiency 4% higher than the E45. The HC hydrocyclone increased the concentration of the initially diluted current (1.0% v/v) to about 45% v/v with low energy consumption (Eu = 1279). Therefore, this device (HC) was the best thickener hydrocyclone ever developed by our Optimization study of thickener hydrocyclones ScienceDirect

CFD Modeling of Hydrocyclones—A Study of Efficiency
A better separation efficiency results in higher pressure drop values. Sun et al. [13] performed a multi-objective optimization; the variables they optimized were the pressure drop and the collection efficiency. In that study, it was found that the inlet and vortex finder diameter Figure 1.

If a 35 mm nominal diameter hydrocyclone removes these droplets under a given set of conditions (temperature, ph, etc.) above those having a mean size of 8 µ and that portion of the disperse phase above 8 µ represents 80% of the distribution, D 80, then the hydrocyclone efficiency is 80% and the droplet concentration at the underflow outletIn addition, at a 95% confidence level, the vortex finder height (L v) and cylindrical hydrocyclone diameter (D c) at the defined three levels do not cause a significant change in the results of the mass removal efficiency and the cut diameter, respectively. Thus, the selection of any one of their defined levels in this study was acceptableOptimization of closed underflow mini-hydrocyclones
