Increasing the Performance of Vacuum Membrane Distillation Using Micro-Structured Hydrophobic Aluminum Hollow Fiber Membranes

PVDF Hollow Fiber and Nano Fiber Membranes for Fresh Water Reclamation using Membrane Distillation

Polyvinylidine fluoride (PVDF) hollow fiber and nanofibrous membranes are engineered and successfully fabricated using dry-jet wet spinning and electrospinning techniques, respectively. Fabricated membranes are characterized for their morphology, average pore size, pore size distribution, nanofiber diameter distribution, thickness and water contact angle. Direct contact membrane distillation (D...

Metal–Organic Framework-Functionalized Alumina Membranes for Vacuum Membrane Distillation

Nature-mimetic hydrophobic membranes with high wetting resistance have been designed for seawater desalination via vacuum membrane distillation (VMD) in this study. This is achieved through molecular engineering of metal–organic framework (MOF)-functionalized alumina surfaces. A two-step synthetic strategy was invented to design the hydrophobic membranes: (1) to intergrow MOF crystals on the al...

Municipal Wastewater Treatment Using a Hollow Fiber Membrane Bioreactor

A bioreactor equipped with hollow fiber microfiltration membranes was applied for wastewater treatment. Removal of chemical oxygen demand (COD) and biochemical oxygen demand (BOD5) was investigated. The experimental setup consisted of influent and effluent tanks, and membrane modules using Polyvinyl Di–Fluoride (PVDF) hollow fibers. The operation program included suction and backwash...
