Caustic Recovery

Caustic Recovery

Caustic Recovery

(OP)
I am looking at cleaning up several caustic streams for reuse.  We are going to use MF and/or UF membranes for organics and solids, but we would like to also remove chlorides.  We have approximately 30 gpm of a 4% caustic stream to work with (100 - 120 'F).  

I have only seen on outfit claiming they can do this using special IX methods.  Any suggestions would be appreciated

RE: Caustic Recovery

Allied Chemical developed an electrodialysis process variation with bipolar membranes several years ago that may help you out with your problem. There are two product streams; one acidic and one basic.

I have lost track of who owns the technology now. This may be you only alternative to the IX process.

Good luck.
