3 Proven Cheapest Way to Remove Iron from Well Water

2021-1-14 · Manganese greensand is one of the oldest oxidizer used to remove iron from water. it uses a real powerful oxidizer called potassium permanganate. Similarly, like water softener, the system regenerates and draws some of that oxidizer, the potassium permanganate, up through the manganese greensand media. It is very effective method to reduce iron.

Stainless Steel Iron Contamination | Stainless Foundry ...

The iron is converted to iron oxide which can then be removed by abrasive blasting. This method is acceptable for unmachined sand castings since the scaling which occurs is not detrimental. The sand blasting abrasive must be free of iron contamination or the part will be re-contaminated.
