title: Filtration rates of pharmaceutical suspension systems.
abstract: This study was undertaken to find it a correlation exists between the filtration rate and the Hu/Ho ratio. For this purpose, flocculated and coagulated structures of sulfamerazine were used. Suspension settling profiles and filtration rates, using additives and additive-free sulfamerazine suspensions, were studied. A straight-line correlation was found. Effects of filter bed parameters on refiltration rates were studied, and a relationship was found by the use of the Kozeny-Carman equation. A straight-line relationship existed between the H1/Ho ratio and the filtration rate exhibited by the different suspension aggregates.
