my sample water TDS is 68000
But i need to convert the below 1000 TDS?
Kindly give me your valuable suggestion .
If it is possible to filter the Polyurethane foam or Zeolite or clay to reduce the that much TDS ?
Dear Vignesh,
in the case of the mining industry, i might suggest the following solution.
At open pit mines of Kuzbass (Russia) we use an artificial filter arrays, e.g. overburden dumps. Some results of using of this technology you can see there:

also till the end of Dec.2015 in Pollution Research another paper on this problem ("The low-cost technology of quarry water purifying using the artificial filters of overburden rock") will be out of print.
Feel free to contact me if any questions will be.

you can use a sludge having undergoes a wash acid which could increase the biosorption of dissolved salts and thus decontaminate the water.
There is no easy way to do this for your purpose. Possible ways include chemical precipitation, electrodialysis reversal, nanofiltration, reverse osmosis, evaporation or membrane distillation and most likely it will be a combination of some of the above depends on your specific water chemistry.
It depends on the type of TDS. If it has a hardness component then raise the pH to reduce the solubility of the C++, then try ion exchange. Otherwise, some kind of filtration -- as Maxim mentioned, above. However, is it due to high salts? Is it brackish, due to sea water intrusion? (You don't mean TSS, do you?)
I agree with Rihua Xiong and Joseph D. Rouse. You can use a combination of chemical precipitation plus biofilters or Revers Osmosis (RO). Also you can use a softener for reduction of hardness and the using of anion-cation resin.
Also evaporation and distillation is an option.
