ForwardOsmosisTech’s guide to measuring FO membrane performance

ForwardOsmosisTech has made an extensive guide on how to determine FO membrane performance in a standardized way And we're very proud of our most recent work. The guide covers the following topics: Membrane form...

BBC Horizons: forward osmosis for industrial wastewater treatment

The concept of using forward osmosis for industrial wastewater treatment was recently covered in a BBC Horizons episode for BBC World News Earlier this year, Sharanjit Leyl from BBC World News visited...

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...

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...

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...
FO mode vs PRO mode

The difference between a PRO process and the PRO membrane orientation mode

PRO process vs. PRO membrane orientation mode - a question from one of our readers   Recently, ForwardOsmosisTech received the following email from one our readers: Hi I'm really confused, and have one question about...

Water filtration by forward and reverse osmosis explained in 4 paragraphs

The shortest possible explanation of water filtration, forward osmosis, and reverse osmosis - here's our attempt Membrane based water filtration systems and processes require energy to extract clean water from impaired water...

Inquiry: draw and feed circulation paths in FO modules

How do draw and feed streams circulate in an FO module? Most of us who are interested in forward osmosis technologies and their applications are familiar with the general concept of how...
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...

Forward osmosis draw solutions and draw solution recovery methods

Draw solutions and draw solution recovery methods are key to unlocking the business potential of forward osmosis I am a membrane enthusiast working in Aquaporin for the past 3 years. Previously, I...
