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...
Schematic diagram of a forward osmosis membrane in action

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...

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...

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...

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 scarcity in 2025

How forward osmosis can help cut energy usage in industrial water treatment processes

The main challenge with today's water treatment technologies Today's water treatment technologies are effective but not always efficient. As a result, considerably more energy will be needed to replenish ever dwindling fresh...
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...
Relationship between forward osmosis membrane structure and performance

The relationship between forward osmosis membrane structure and performance by Tiraferri et. al. 2011

Why Tiraferri et. al. 2011 is a must read within the field of forward osmosis membrane development. In their article "Relating performance of thin-film composite forward osmosis membranes to support layer formation...
