Abstract
Normally, the filtrate space of a plasma separator is not fully charged with plasma, with the result that filtrate pressure is measured at the upper aperture of the filtrate space. In a previous study filtrate pressure was measured considering the static pressure of the filtrte which filled the filtrate space. In membrane plasma separation, TMP is usually vanishingly small, so that an exact method for measuring filtrate pressure needs to be developed. This method recommends itself for filtrate pressure measurement. Correct filtrate pressure makes it possible to obtain pure water permeability Lp and TMPc (TMP at commencement of hemolysis).
