The haemodialysis system: basic mechanisms of water and solute transport in extracorporeal renal replacement therapies.

phenomena came from industrial chemistry, and diaJc=Qf·Cb·S lysers were designed to be ideal counter-current being in ideal conditions: S=1–s, where s is the exchangers [2]. Only later was convection used in reflection coefficient of the membrane. These definiclinical practice, showing potential depurative advanttions present convection and diffusion as two separate ages [3,4]. At first, ultrafiltration was employed to phenomena. However, it is impossible to define pretreat overhydrated patients [5], but soon the removal cisely the contribution of each single process to the of solutes by convection thanks to the ‘solvent removal of solutes because of their continuous drag’ phenomenon was utilized for blood purification interactions.
