Synthetic solution or liquid contains chlorine and metal oxides such as iron, calcium, magnesium, sodium, potassium and aluminum.

My goal is to remove chlorine and all of these oxides except aluminum from the solution. So what method or chemicals should I use to preserve aluminum oxide and remove other impurities?

Thanks

1. Dear Alireza, 
   Recently we investigated electro-oxidation (www.noahws.be) with this technique you could convert the chloride present in the waste water into bleach. Hereby reducing some of your chloride (20%) but giving it a useful function (disinfection, oxidation of organic pollutants). Afterwards with a pH increase like David suggested or with electrocoagulation like Abdul suggested you can remove most of the iron, calcium and magnesium. Unfortunately with these techniques you will not be able to remove the sodium and potassium.

2. Electro-Coagulation

   

   Demand for advanced, industrial waste water treatment systems is being stimulated by increasingly stringent legislation relating to the disposal of waste water.

   The rising cost of process water is forcing industry to adopt water re-use systems. 

   Electro - Coagulation provides  chemical free water treatment of aqueous waste streams and is suitable for a wide range of waste waters 
   of single or combined element contamination. 

   This is the best way to remove almost all contaminants from the effluent

   The other way is the coagulation process by using coagulation process

   Please see the detail below:

3. Your best bet is vigorous aeration which will reduce the chlorine.

   Then adjust the pH to optimize the precipitation of other metals but keep the AL in dissolved form.  (SEE Practical Wastewater Treatment by D. L. Russell  and the figure below)  The Chlorine can be removed by vigorous aeration

      Do you think that with this method (vigorous aeration), chlorine and other metal oxides can be removed from the solution and aluminum oxide can remain in the solution?

4. chlorine is easy. Just add a little reducing agent  like sodium bisulfite or thiosulfate or hydrogen peroxide. Yes , peroxide is a reducing agent in the  present of oxidizing agents, If you make the solution slightly basic, aluminum hydroxide will form a gelatinous precipitate.

      Can we really remove chlorine and other metal oxides by adding sodium bisulfite or thiosulfate or hydrogen peroxide, and finally obtain a gelatinous precipitate of aluminum hydroxide? If you have an article about this, please send it to me. thank you

5. Have you tried an alternative disinfection methode, such as hydrogen peroxide?

      No. Do you think it can help remove these metal oxides and chlorine?
