How to Clean Water from Iron

Iron - one of the most common chemical elements in nature. It is universally found in various layers of soil, and therefore it is not surprising that groundwater is overly enriched with this mineral. In addition, in addition to natural ways, it can penetrate into drinking water from rusty water pipes, which are everywhere in old houses. Drink or use for cooking such water is extremely undesirable. The question arises: how can I clean the water from iron? There are several methods for this.

Before proceeding with cleaning, you should find out from what type of iron located in the water you want to get rid of:

If the water from your crane is clear and transparent, but after settling at the bottom of the vessel, a brown precipitate is formed - there is a bivalent iron in it. This type of water pollution with iron is the most common and occurs about 85% of residential buildings.
The trivalent iron cannot dissolve, so water with its content has a yellowish shade, accompanied by the appearance of a brown sediment in the process of settling.
If water has a pronounced yellow shade, but after settling the precipitate is not formed - iron is present in the form of organic compounds with molecules of other substances.

To date, the most efficient water purification system in domestic conditions is the method of reverse osmosis. It is based on the use of several filters connected to each other, falling into which water is cleaned from large elements (sand, sludge, chalk), various precipitation and chlorine. Then, toxins, organic impurities and heavy metals are removed on the molecular level of water. A high-quality filter can give a practically one hundred percent guarantee for water purification from unwanted impurities.

The ion exchange method of cleaning is less efficient than the method of reverse osmosis, but also gives good results. Its essence is that the cartridge containing ion-exchange resins is installed inside the filter. Depending on its design and the used resins, such cartridges can effectively purify water to the level of iron content in it 5 milligrams per liter.

The widespread filters using calcite - natural material, which is able to effectively delay the iron dissolved in water. This method is called "alkaline plant" and is most often used in conventional household filters.

In addition to special filters, it is possible to clean the water with ordinary upholding. To do this, type water in a large vessel and leave for 8-12 hours. After iron-containing impurities fall at the bottom - drain clean water.

Now you have been understanding that iron in water can be in a variety of forms, and you know which way you can get rid of it. But to accurately determine the filter you need - make analyzes your water in the laboratory. The results will give an answer not only to this question, but will be able to indicate the presence of other impurities, to remove which you can correctly select high-quality cleaning equipment.

Good day! The iron content in my water from the well is 2.4 +0.36 -0.36 mg / l (I made an analysis). Water with a set clean and transparent, like a tear. Slightly stand and yellow, and then it becomes transparent again. At the bottom of a small sediment of white or slightly yellowish shade. After the kitchen filter, the barrier water is generally transparent and costs any muddy as you like. What will you advise me for cleaning from iron, - what equipment? Can I drink it?
