Matthew Brannock Thanks Very much for your interest ,
 you accurately what's happening in my process and our process is seeded slurry technology, but the issue that the mixing of feed streams occur in separate tank not containing seeds (interstage tank) . and scale mainly occur in this tank.
Can you advice if adding acid on this mixed streams will help or not.

Or

preparing seeds in this tank and then restart feed streams again, and transfer to FFE while the re-circulation line of this tank opened to be sure that there will be minimum Seeds available there.

Hi Tamer,

If the scale formed is in fact calcium carbonate, then destruction of alkalinity using acid would certainly be an option (we're currently working on a project where this is undertaken).  Understanding the implications of adding acid is also necessary though.  

For example you also have to be careful that if you dose sulphuric acid it doesn't take you over the CaSO4 precipitation point too early in the process in locations where it would be inconvenient.  HCl may be an option but is much more expensive.  Modelling can help with this along with an ion balance composition from both streams.  

Without knowing the process in detail, I can't say whether preparing the seed in that particular tank is going to create an issue for you.

Cheers,

Matt.
