How does a spiral wound membrane work?
How does a spiral wound membrane work?
Spiral wound modules (see Figure 3) consist of a sandwich of flat sheet membranes, spacers and porous permeate flow material wrapped around a central permeate collecting tube. The permeate flows through the membrane in cross flow to the feed solution, that is radially inwards towards the central collecting tube.
How does a membrane contactor work?
A membrane contactor is thus a device that achieves gas-liquid or liquid-liquid mass transfer without dispersion of one phase within another. The main role of the membrane is to act as a barrier and to increase the surface for mass transfer exchange between both phases.
What is spiral wound membrane?
Description. Spiral-wound elements consist of membranes, feed spacers, permeate spacers, and a permeate tube. First, a membrane is laid out and folded in half with the membrane facing inward. The feed spacer is then put in between the folded membranes, forming a membrane sandwich.
How many types of membrane modules are?
So far, there are four kinds of membrane modules that have been widely used in industry. They are (1) tubular modules, (2) hollow fiber modules, (3) flat sheet modules, and (4) spiral-wound modules.

What is hollow fiber membrane contactor?
A membrane contactor is a device that achieves gas/liquid or liquid/liquid mass transfer without dispersion of one phase within another. This is accomplished by passing the fluids on opposite sides of a microporous membrane.
What is the pore size of microfiltration membranes?
between 0.1 and 10 µm
Microfiltration (MF) membranes are normally of average pore size between 0.1 and 10 µm where pores are uniformly distributed throughout the membrane.
What is the principle of reverse osmosis?
Reverse osmosis ( RO) is a water purification process that removes ions, unwanted molecules and larger particles from drinking water using a partially permeable membrane. As a result, the solute is kept on the membrane’s pressurized side and the pure solvent is allowed to pass to the other side.
How does a spiral wound membrane ( Ro ) work?
How Do Spiral Wound Membranes work? In the spiral wound membrane configuration, a flat sheet membrane and spacer are wound around the permeate collection tube to produce flow channels for permeate and feedwater. This design maximizes flow while minimizing the membrane module size.
