Ceramic membranes are able to separate oil and water with a maximum oil content inside filtrate about 5 ppm.
These type of membrane are laready used onboard for bilge water treatment.
Orelis Environment, located in France, provides KLEANSEP membrane (www.orelis.com)

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

Dear sir
Orelis Environment provides ceramic membrane unit KLEARSEP dedicated to bilge water treatment. Oil detection is done on line using Bilgmon 488 produced by BRANNSTROM - Sweden

Dear sir
recirculation pump is used to beat modules pressure drop and generate appropriate linear velocity.
Feed pump is used to control inlet module pressure

Dear sir
Which type of flat membrane - ORELIS (France) from Novasep group produce flat sheet membrane which are used, since many years, inside MBR unit worldwide
Visit web site and feel free to ask question

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)
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.
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...
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.
Orelis (Novasep group) produce ceramic and organic membrane used for oil/water separation
Ceramic membrane are already used on ferry for bilge water treatment - Orelis organic membrane are installed on cruise liner QM2
