Is there any difference between the membranes Ovivo uses for MBRs vs those for membrane thickeners?
No, Ovivo uses the same membranes for liquid and solids treatment. The difference lies in how we apply the membranes. In a typical MBR application a flux rate of 15 gallons per square foot of membrane material per day is normal. As the solids in a membrane thickener are much higher than they are in an MBR we derate or lower the flux rate for thickeners to approximately 5 gallons per square foot of membrane material per day to prevent premature fouling.
