Forward osmosis (FO) membranes and membrane processes

Q: What is a membrane? In the context of the water treatment industry, a membrane is a thin, porous structure that can be used as a selective barrier between two aqueous solutions...

Forward osmosis video tutorial

Breaking the ice with a forward osmosis video tutorial Forward Osmosis technology is still a novel and developing technology. And as something innovative and original, it comes with some degree of excitement...
Membrane fouling in forward osmosis processes

Membrane fouling in forward osmosis (FO) processes is reversible

Membrane fouling in reverse osmosis and forward osmosis processes The difference in membrane fouling between reverse osmosis and forward osmosis processes can be attributed to the underlying driving force for water transport. In...

S-parameter calculations yield negative values – what to do?

What to do when structural parameter equations yield negative S-values? We recently received this question from Maxime, a Phd student at KU Leuven, who is working on TFC membranes for forward osmosis...

Draw solutions and their recovery methods for dairy and food industries – a brief...

Introduction Currently, Forward Osmosis (FO) is well suited for applications in which water needs to be removed in a gentle manner (e.g. food processing and concentration of valuable such as flavors &...

New calculator for estimating structural parameters (S-values)

The structural parameter (S-value) of a forward osmosis membrane determines how severely the membrane is affected by concentration polarization This makes the S-value one of the 3 most important FO membrane performance...
