TDS removal

[Bharat Lodha]

Please suggest me some technology which can remove TDS as high as 200000 mg/L.  Is there any technology available? Your input will be highly appreciable.

Thanks

My suggestion is the Chemical Precipitation is the most cost effective way to move ahead with such a high TDS. Handling sludge is tough in this process.

The other technologies are expensive. You can try several other methods which are available.

My suggestion would be first you go for sedimentation, this would reduce the dissolved solids then you go for chemical precipitation......

Thanks, but chemical precipitation would not remove mono-valent ions.

I don't have concern with dissolved solid. the concern is only TDS

Dissolved solids means TDS,

What is the difference ????

[Piyush Gupta]

Can you please tell me the full form of TDS....  its one n the same thing...

[Durga venkata prasad.G]

Totally dissolved solids

Dear sir, sedimentation is removing the TDS ??????

[Piyush Gupta]

Dear Sir,

Yes, definitely. In sedimentation hydraulic flow speed is very less for effective sedimentation, even if waste water is in still condition after some time you will able to see scale formations and salts are deposited at the bottom.

Sorry i mean to say suspended solids

I don't have concern with suspended solids, that can be removed using sedimentation. My main concern is dissolved solids, which is mainly due to high concentration of soluble ions like Na, Mg, Ca, Cl, SO4, Fe etc.

can we use any technology other than distillation/evaporation, crystallization for removal of such high TDS?
