    Membrane: Varying pressure drop for flow rate

    Dear sir Drop pressure (DP)is in relation with retentate flow and viscosity. Linear velocity along membrane drives DP. Permeate flow is in relation with TMP but there is no crosslinking between these two parameters Best regards

    Membrane filtration for use in wine filtration

    In France, ceramic membranes are used for wine filtration Trade mark : Kerasep 0,1 µ same ceramic membranes are used for spring water filtration after oxydation step using air (iron and maganese removal)

    Membrane materials with uniform pore size.

    Pore size is managed by sittering temperature (about 1200 °C) during ceramic membrane production Pore size is managed by phase inversion process during organic membrane production - Polymer concentration in the collodion used for membrane production determines pore size.

    ultrafiltration optimisation

    Process parameters are different according membrane type 1) Ceramic tubular membrane : linear velocity along membrane must be around 5 m/s - pressure at the module inlet will be about 5 bars to maximise permeate flux 2) Organic plate and frame membrane (Orelis membrane) requires a lower velocity...

    electrocoat and membranes

    organic ultrafiltration membrane are used to separate paint from demi water - organic membrane have the same electronic charge than paint - for instance positive membranes are used with cationic paint (+) to avoid membrane fouling.
