Based on experimental data, simple, linear system models were derived for the mean drop diameter and the interfacial area using the stirrer speed as input variable.

Natural minerals have become the focus of denitrification catalyst research because of their advantages of large reserves, low price, and environmental protection. A large number of rare earth tailings have brought great pressure to the ecological environment, and the elements that are rich in Fe, Ce, and other elements conducive to catalytic denitration have not been effectively utilized. In this paper, 7.5 wt % Mo/magnetic separation of rare earth tailings was taken as the object. In order to further improve the denitration efficiency of the catalyst and broaden the reaction temperature window, the hydrothermal reaction time and hydrothermal reaction temperature of the catalyst were adjusted during the preparation process. XRD, SEM-EDS, BET, H<sub>2</sub>-TPR, NH<sub>3</sub>-TPD and other characterization methods were used to study their effects on the performance of Mo-modified rare earth tailings catalysts.

To date, a remarkable amount of data is available on the application of membranes in diverse domains such as industrial wastewater treatment, food processing, and medicine. It is becoming a severe issue when process sectors like mining, metallurgy, and petrochemicals discharge oily wastewater. Although oil–water emulsion separation using membrane technology is successful, this method suffers from a serious flux declination problem brought on by fouling during filtration. Keeping this in mind, the aim of this paper is to highlight the recent advancements in the synthesis of ceramic membranes from several perspectives such as feed pretreatment, membrane cleaning, proper operational conditions, and the use of antifouling coatings. Recent study has indicated that surface hydrophilization is the key emphasis in mitigating membrane fouling.
