Forward Osmosis (FO) Membranes

Forward Osmosis (FO) Membranes

Specifications

FTS H2OTM
Membrane materialCellulose Triacetate (CTA)
Operating conditionsMax. Operating Temperature: 50 °C
pH range: 3-7
Maximum Chlorine 2 ppm
Minimum Transmembrane Pressure: 5 psi*
Max. Inlet Pressure 75 psi
Recommended Pre-filtration: 100 um or lower (if particulates are present)
Packaging and storageRefrigerated storage is recommended (3-25 °C)
Membrane must be kept moist at all times1
Do NOT allow the membrane to freeze2
Do not store in direct sunlight
 Shelf lifeUp to 3 years

1 Maintain higher pressure on the retentate feed side. Control permeate (draw solution) side to have some pressure and flow to keep minimum transmembrane pressure at 5 psi or above.

2 If membrane dries out, it is impossible to re-wet and should be discarded. If membrane freezes, the pore structure may its lose integrity and the membrane should be discarded.

Applications

Forward Osmosis technology is most commonly used for an array of wastewater recycling and water reclamation applications. Areas in which an FO cell may be used include:

Water reclamation from oil and gas exploration

Landfill wastewater

Alternative energy/biogas wastewater

Medical/dental wastewater

Membrane bioreactors

Seawater desalination

Radioactive wastewater

Carpet manufacturing wastewater

Pressure Retarded Osmosis (PRO) to generate electricity

Other uses for Forward Osmosis Cells:

Pretreatment for Reverse Osmosis procedure

Concentrating juices (grape juice to wine, tomato paste)

Pharmaceuticals

Nutraceuticals
