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...

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...

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...
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...
