Novel Fiber Membrane Distillation Process

Using hydrophobic hollow fibers to make air gap membrane distillation processes more cost-effective, efficient, and compact. Background: < Membrane distillation (MD) is a water distillation method that involves the use of hydrophobic membranes and their properties. MD allows for water vapor to permeate through a membrane but prevents...

Apparatus for Electro-Blowing or Blowing-Assisted Electro-Spinning Technology and Process for Post Treatment of Electrospun or Electroblown Membranes

Use of electrospinning and melt-blowing processes for a higher yield, more efficient production method of fiber manufacturing. Background: Electrospinning is the process where an electrostatic field is strong enough to overcome the surface tension of a liquid. This process allows nanofibers to have a very large surface area to volume ratio, thus having...
