Removal of the Total Dissolved Solids mean Desalination process. The choice of the method ( R.O or Evaporation-Condensation depend on many parameters as cost ,area ,quantity ,use after treatment& the physic- chemical  parameter such as T.D.S ,Temperature.Most likely the method would be Evaporation-Condensation (multi stage flash evaporation MSF).

1- Drain some of high TDS and do makeup with low TDS fresh water.

2- Re-treat the high TDS water with R.O unit and recycle again

There are two ways

Reverse Osmosis Method.

Ion exchange Method.

We can solve this proble by using above two methods.If we want to reduce 1200 ppm TDS to 600 PPM , then half of water passsed through RO plant or Ion exchange towers where positive and Negative Ions exchange into H and OH ions.

by adding an oxidation bacteria to move the dissolved  organic mineral  in the water and filtrate it  by active carbon

The use of RO (Reverse Osmosis) system will lower the TDS levels.

 by using  Evaporation and  condensation process we can remove up to 40,000 TDS to 800 TDS .

we will use pre filteration system and Sand filter.also we will use specific chemicals for example Antiscanlant & Sulfuric Acid.

First of thing, classify the hardness to find the proper pretreatment way to decrease the hardness precipitation so will be ready for further salt removal by (I prefer) Reverse Osmosis
