How to increase concentrat flux?

I'm a student on water engineering I'm designing a plant and the concentrate flux is less than the minimum how I can increase it without changing the permeat flux or recovery. thank you.

1. you can increase flow trough the vessels by changing from christmastree design to a feed and bleed mode.

2. You can recirculate some concentrate back to the inlet.

   if there are multiple vessels change the number of stages and vessels per stage.

3. You can use a successive RO process where in the first stage you can set a higher level of flux of reject, using the reject for the second phase RO, and use the reject form second for third stage.   After the direct membrane filtration of wastewater, a typical phases of recovery can be 65%, 10% and 5%.  Based on the feed water quality you can increase or decrease the flux on rejects.  I hope that helps.
