This often involves the use of one or more of the filters shown on the diagram on the right. The removal of iron from well water first involves identifying the type of iron present in the water supply (ferric, ferrous, or iron bacteria), measuring its concentration in ppm, measuring the pH of the water, and then applying the appropriate method of iron removal, either through oxidation, ion exchange, greensand, or chemical feed. If you have a ‘constant pressure’ or variable-speed pump, this test as described below won’t work.

I’ve noticed people who live in the country, without city water access, often have a rust discoloration in their sinks. The Best Water Softener to Remove Iron from Well Water Supply. Yes, a reverse osmosis system can remove iron present in water. This is known as pressure tank ‘draw down’.

Using the filter, you can get rid of the worries of staining and scale buildup, which can cause damage to the appliances and plumbing systems. This interaction may result  in hydrogen sulfide gas only in the hot water. Using oxygen in the air, an air injector converts the ferrous to ferric. These five major complications of borehole and well water are resolved by just one filter, instead of conventional approaches which require a separate filter for each problem. Iron becomes part of their cell walls and the end result is a slimy stringy growth that can be seen in toilet flush tanks. Ferric Iron is clear well water that has been exposed to oxygen, oxidized forming visible rust, giving the water a reddish color. A Katolox filtration system is able to remove both forms of iron, magnesium and hydrogen sulfide present in well water.
