Abstract The development of eco-friendly adsorbent with perfect solid/liquid separation performance is of great practical importance for the efficient purification of dye-containing wastewater. Herein, cellulose based cation-exchange fibrous bio-adsorbent (CEF) was successfully obtained via an industrialized cellulose etherification process. The fiber morphology can be maintained with the average degree substitution (DS) of CEF as about 0.19. The CEF showed high efficiency adsorption for methylene blue (MB): achieving 82% of equilibrium uptake (447.69 mg·g-1) within 5 min. Especially, the non-woven porous filter material, formed by CEFs and glass fibers, showed the praisable solid/liquid separation characteristics, fast water filtration rate (≈ 6.3 m3·m-2·h-1) and high removal rate (≈ 99.2%) when it was used to adsorb MB (150 ppm) from wastewater. In addition, CEFs filter material can be regenerated via a simple method. This study demonstrates that green natural fiber materials are promising for the economical and efficient purification of dye-containing wastewater.

Background: In recent years, a kind of drilling method of Solid-Liquid separation combined with pulsating vacuum formed by vibrating screen and compressed air injection has emerged in oil drilling, which greatly improves the gas, solid and liquid separation ability of the drilling fluid vibration screen. Objective: Based on the above ideas, a kind of hydrocyclone used for gas-liquid separation with the pulsating feed boundary was proposed. The separation performance of gas-liquid hydrocyclone may change greatly due to the mixed pulsation of the gas-liquid fluid transported by the jet pump. Therefore, the flow characteristics of the pulsating feed hydrocyclone need to be analyzed and explored to provide basic data for further improvement of structure. Methods: The development status of cyclone separators are summarized through related literatures and patents investigation. The Computational Fluid Dynamics (CFD) software ANSYS Fluent 2019 R3 is used to analyze the flow field characteristics and optimize the parameters of the hydrocyclone with stable feed. Then, programming by the User-Define-Function (UDF) of Fluent is used to simulate the flow field of the separator under the condition of pulsating feed, meanwhile, the flow field analysis and parameter optimization are carried out accordingly. Results: The optimal parameters in stable state and pulsed state are obtained through the analysis of efficiency curve. The results show that the flow field can be stabilized in the pulsating feed state, and the sinusoidal pulsing with a frequency of 0.4Hz is used to achieve the highest separation efficiency, reaching 85.5%. Conclusion: The separators with pulsating feed and stable feed have similar flow field characteristics, and the optimal structural parameters under pulsating feed are obtained. Compared with the stable feed condition, the pulsating feed condition can connect multiple cyclone separators, which can separate more drilling fluid in unit time, and the work efficiency could be improved. It has a strong practicability, which provides an important basis for the structure optimization in future.

Liquid Separator

In order to evaluate the separation efficiency of each module in this type of novel combined separator, by PDPA(Phase Doppler Particle Analyzer) we find that under different conditions in 6 combinations, combination 6 (including cyclone + stabilizer + blade+ baffler) has the highest separation efficiency, and there are relatively efficiency valley region in all the 6 combinations. Under the same conditions, the average separation efficiency of the baffler is higher than the blade, and then the blade and baffler have their own advantages in different flowrate. To use stabilizer can effectively improve the flow field inside the separator, restrain and reduce vortex and backmixing, more conductive to the gas-liquid separation.
