Hollow fibre modules made from hollow fibre forward osmosis membranes
Hollow fibre module summary
|Packing density||up to 1600 m2/m3|
|Advantage||ideally suitable for high volume applications due to high packing density and resulting small module footprint|
|Disadvantage||prone to fouling / membrane clogging at low concentrations of fouling agents|
Hollow fibre modules are basically tubular modules with very high packing densities (see the table below), and are used extensively for large-volume water treatment applications, such as desalination of seawater via reverse osmosis processes, where a small module footprint is essential for the economical viability of the given membrane installation. Hollow fibre membranes are prone to fouling and clogging due to their small internal diameters. This is also the case for forward osmosis hollow fibre membranes and therefore usage for industrial water treatment is limited to applications where waste water streams contain low concentrations of fouling agents. Such applications include:
- Downstream waste water processing steps
|Hollow fibre length||1m|
|Hollow fibre wall thickness||0,2mm|
|Hollow fibre inner diameter||1mm|
|Hollow fibre inner area||0,0031m2|
|Inner diameter of module||90mm|
|Number of hollow fibres in module||3227***|
|Internal volume of module||0,0064m3|
|Active area per module||10m2|

Excuse me, I would like to know this price of Hollow fibre modules for FO process. I need it for my project calculation in order to find economic analysis. Thank you.
I am representing Aquaporin, where we have developed Hollow Fibers for FO. For more information please visit our homepage at aquaporin.com or you can contact me directly at email@example.com. I will be happy to help you with HFFO for your project.
All the best
Hello, I am looking for a Hollow Fiber Modules for use as an alternative to 0726710U PUR MDL PSH-330-8 PVDF WS.

Please contact me by email. I look forward to hearing from you.
I don’t know of any forward osmosis modules that are capable of replacing the one from Koch you’ve linked to.
I am looking for a small HF module for cellulose acetate composition please quote me
Did you try reaching out to Aquaporin? They have small HF modules based on TFC membranes. I’m not sure where you can purchase small HF modules made from cellulose acetate. Perhaps from Toyobo?
