 Dear Ebrahiem Esmail Ebrahiem,

Reverse Osmosis can remove 90 - 95% of the chlorides because of its salt rejection capabilities. Electrodialysis and distillation are two more processes that can be used to reduce the chloride content of water.

Reverse Osmosis

Dear Ebrahiem,

It is possible to reduce the chloride content of water by several methods, provided that the total or partial reduction can not be achieved independently of other ions in the water.

 The methods are as follows:

- Demineralization on ion exchange resins

- Reverse osmosis

- Electrodialyse

- Boiling off - Evaporation

These processes have a cost, both for the installation and for the operation and it is this cost that determines whether the removal of chloride of water is economically viable or not. Indeed, it is possible that the cost of m3 of treated water is crippling.

Once the rates are high (tens or even hundreds of m3 of water per hour), installation and operating costs are high.

In fact, the technique depends on the destination of the water and everything depends on the results of the scoping study that is made. The problem is the cost of demineralized water.

If water is for boilers of camp, the process etc., all above techniques can be retained.

With my best regards

Electroosmosis

Dear Ebrahiem. You can use Revirse osmosis (RO) system 

There are various processes but is more efficient by Revirse osmosis system.

Chlorides in water / wastewater are a serious concern in the era of water conservation and reuse. There is a need for different methods which are low cost and efficient. The above paper is an effort towards finding such a method. From the above paper, the following conclusions may be drawn. 1. By using plant biomass of Parthenium, chloride removal of 30- 34% can be achieved. 2. The required pH for this process is 7 – 7.5 3. The required contact time is 120 minutes The biosorption efficiency decreases with increasing concentration of chlorides.

This is Hard water consistent with high Ca, Mg and their carbonates.The RO technology may be useful, it may reduce TDS  less than 50 mg/lit.  Technology depend on requirement of TDS. However dilution method can also be experimented.

distillation and RO are good methods. But electrochemical techniques can also be used.

Reverse osmosis is the best technology, but your water hardness is too high. You need to remove hardness before removing chloride. I recommend to first remove hardness with a softener (cationic resin) and then remove chloride and sodium (because cationic resin treatment will increase sodium content in softened water) with a reverse osmosis system.

Note that just hardness and chlorine are not sufficient parameters to design a reverse osmosis system. You'll need full analysis of your water quality to help system designers make all similations necessary to design a reverse osmosis system.

Regards,

In most cases reverse osmosis (RO) technology is mostly preferred because it removes up to 95% of Chlorides due to salt rejection capabilities. You may also consider distillation or Electro- dialysis.

Hope it helps!

Adsorption

Demineralization and Reverse Osmosis as well as the aeration of waater help in reducing Chloride, while Chlorine can be reduced by Activated Carbon, Sulfur dioxide gas or by Ammonia

The best solution for reduction of chlorides in water is Reverse Osmosis

You can chose between adsorption and reverse osmosis which give a good results for the elimination of chloride 

you can try with adsorption with an activated carbon filter.

Reverse Osmosis (RO) is best method. However many electo chemical methods can be use.

It can be removed with the UHLA (ultra high lime aluminium) method:

you need lime (3-4 times of chlorides), sodium aluminate NaAlO2 or the same hydrated (1-2 times of chlorides). It can crystallize Ca-Cl aluminate, insoluble and you can remove it from the water. In the same time, it can remove sulphates.

Of course, you can produce sodium aluminate by the raction between soda and aluminium (metal): pay attention to heat (-1133 kJ/mol!!) and hydrogen
