Complementing our existing CF042 and Sepa CF membrane/process development cells is the new CF016. Designed for applications with smaller membrane samples or low solution volumes, the CF016 comes in two varieties: a crossflow version that can perform reverse osmosis, nanofiltration, ultrafiltration, and microfiltration separations and a forward osmosis version that can be further modified to perform pressure-retarded osmosis.
In the crossflow version of the the CF016, feed solution enters the membrane cavity in the cell body, flowing tangentially across the membrane surface. Applied pressure forces a portion of the stream to permeate the membrane and flow through the permeate carrier located on the underside of the top half of the cell, finally exiting through the outlet on the top of the cell into a user designated collection vessel. The concentrate stream, which contains the material rejected by the membrane, continues sweeping over the membrane, exiting via the concentrate outlet on the underside of the bottom half of the cell into a discharge vessel or back in to the feed vessel.
In contrast, the forward osmosis version of the CF016 works by having both a feed solution and a draw solution entering the cell body. The two solutions are separated by a membrane and the difference in concentration between the two solutions creates osmotic pressure which pushes a portion of feed stream through the membrane as the two stream flow past each other.
Currently, the both versions of the CF016 are available with either a delrin acetal or acrylic cell body. You can see how it stacks up against the rest of our membrane/process development products here.
