The CF042- FO Cell is a laboratory-scale filtration unit that is designed to evaluate a variety of Osmotically Driven Membrane Processes (ODMP), including Forward Osmosis (FO) and Pressure Retarded Osmosis (PRO). Available in five different materials for chemical compatibility or for applications requiring visual investigation of hydrodynamic conditions or local fouling intensity. All cells are compatible with our kits, benchtop systems, and skid systems.

Frequently Asked Questions
Q: Are your PP spacers FDA compliant?
Yes, our Bi-Planar Feed Spacer Mesh is extruded from FDA compliant polypropylene.
Q: Why is the flat sheet membrane I'm using measuring a flux value less than the published flux value?
Flow characteristics for a spiral element and flat sheet membrane are significantly different and are really only comparable on a qualitative basis. Variability in the membrane manufacturing process, differences in water composition, test procedures, and test equipment, used in a factory, laboratory, or elsewhere, will impact water flux results.
Q: How do I install/remove permeate fittings or other plastic NPT fittings?
Sterlitech recommends to install all plastic fittings by hand using PTFE tape. If a plastic NPT or compression fitting starts to leak during operational testing, tighten the fitting carefully until the leaking stops. Excessive tightening may break the fitting or damage other components.
If the fittings is broken and stuck in the cell top, use a spiral flute extractor bit or similar tool to release the portion of the fitting in the cell top. If the cell top becomes cracked from removal efforts, a replacement can be purchased.
