Summary: Membrane distillation (MD) is a promising method for treating salty and dyeing wastewater. However, existing MD membranes often face issues like low permeability and membrane pore wetting. In this study, a hydrophobic electrospun nanofibrous membrane doped with Zeolitic imidazolate framework 71 (ZIF-71) was developed, which improved the surface roughness, hydrophobicity, permeation flux, and desalination performance of the MD membrane. The ZIF/PcH membrane showed high stability and excellent pollutant retention rate when treating salty and dyeing wastewater.

Summary: This study aimed to find an effective cleaning method for organic fouling in membrane distillation (MD). The fouling characteristics of humic acid (HA), sodium alginate (SA), and bovine serum albumin (BSA) were investigated, along with the cleaning efficiency of different flushing methods. The results showed that the presence of calcium ions had a varying effect on fouling for different organics. NaOH flushing resulted in irreversible fouling, while DI water flushing showed good recovery for SA-induced fouling.

Summary: This study investigates the sensitivity analysis of seat design parameters and their interaction effects, optimizes the seat design to minimize vibration transmission to drivers, and identifies system parameters from measured vibration acceleration data. A prediction model of vibration transmissibility is developed using the response surface method modeling, and the statistical significance of the model is validated by analysis of variance. The design parameters are optimized using the response surface method modeling and Genetic Algorithm. The proposed method can enhance the vibration isolation performance of existing vehicle seat suspension systems with reduced cost and without additional parts and energy consumption, making design change and optimization of the seat suspension system simple and easy to implement. The vibration transmissibility ratio of the optimized seat system is reduced by about 10%.
