In brief: Good question

Dialyzers are made of a polyurethane capsule within which hollow fibers or parallel membrane plates are suspended in dialysate (dialysis solution).
The fibers or plates act as a semipermeable membrane across which blood and dialysate flow. By crossing this membrane, solutes and water move between a patient's intravascular compartment and the dialysis fluid contained within the dialyzer.

Best resource I've seen is "Help - I Need Dialysis" by Dr. John Agar and Dori Schatel. You can find it on Amazon.com. LGromkoMD
