Slow continuous ultrafiltration (SCUF) is an artificial method which approximately mimics the ultrafiltration function of the kidneys. SCUF is a continuous renal replacement therapy (CRRT) generally used to remove fluid from fluid overloaded patients with acute kidney failure. During SCUF blood is continuously removed from the body, passed ...
Given a transformation between input and output values, described by a mathematical function, optimization deals with generating and selecting the best solution from some set of available alternatives, by systematically choosing input values from within an allowed set, computing the output of the function and recording the best output values found during the process.
Hemofiltration is sometimes used in combination with hemodialysis, when it is termed hemodiafiltration. Blood is pumped through the blood compartment of a high flux dialyzer, and a high rate of ultrafiltration is used, so there is a high rate of movement of water and solutes from blood to dialysate that must be replaced by substitution fluid that is infused directly into the blood line.
As other research has been conducted, it has been argued that using an ultrafiltration pump may not be the best pump for the WAK. For example, research has found that by using a peristaltic pump instead, would allow a person to know their blood flow rate without having a sensor, which is needed in an ultrafiltration pump used in the experiment ...

In ultrafiltration, the molecular weight cut-off or MWCO of a membrane refers to the lowest molecular weight of the solute (in daltons) for which 90% of the solute is retained by (prevented from passing through) the membrane, [1] or the molecular weight of the molecule (e.g. globular protein) that is 90% retained by the membrane.
[3] The suspended liquid is passed through at a relatively high velocity of around 1–3 m/s and at low to moderate pressures (around 100-400 kPa) parallel or tangential to the semi-permeable membrane in a sheet or tubular form. [4] A pump is commonly fitted onto the processing equipment to allow the liquid to pass through the membrane filter.
