Steve mentioned he had high levels of Iron 37 gms/ liter and 2000 ppm salt.
I thought a new topic would be smart.

Recommended Treatment Sequence
Oxidation (Aeration or Chemical):
The first step is to convert the dissolved iron into solid particles. At 37 mg/L, aeration (spraying, agitating, or bubbling air into a holding tank) is an effective and economical method to oxidize the iron.
Chemical oxidation (chlorine or hydrogen peroxide) can also be used.
Sedimentation: After oxidation, allow the water to sit in a tank, letting the solid iron particles settle to the bottom.
Filtration: Pass the water through a multi-media filter (e.g., sand or anthracite) to remove the oxidized iron particles.
Desalination (Reverse Osmosis):
To remove the 2000 ppm salt, a Reverse Osmosis (RO) system is necessary. Due to the high salt levels, a brackish water RO system is often required.
Polishing/Post-Treatment: A UV light may be added to kill any iron-related bacteria.

Hydrogen Peroxide Based Iron Removal Systems
This is my opinion and I have saved the best for last.
Hydrogen peroxide or H2O2 is a much better oxidizer than oxygen and it doesn't require that a service technician move in with you.
Hydrogen Peroxide works every time and since it is such a great oxidizer, it does not leave all that iron sludge to clean up and there are no injectors to plug.
Injecting H2O2 is simple and very low maintenance… and unlike chlorine, the injection point does not plug frequently.
It is not uncommon for hydrogen peroxide to work for 5+ years without any maintenance except for adding peroxide.
Hydrogen peroxide is injected just ahead of a catalytic carbon filter. Not only does peroxide not require contact time, contact tanks or pressure tanks just dilute the H2O2 making it less effective.
That is why a proportional injection system is the most effective method.
Pros & Cons:
The cost of a system is on the moderate to the high side, but it operates for many years without any maintenance... except for adding the H2O2.
An average family will spend $200 to $400 a year on peroxide, but most think that is a small price to pay to have iron-free water.
The only drawback to an H2O2 system is the annual peroxide cost.
