Deferrization of Water

Water supply purification is the key to comfortable living in a private house and apartment. If you use water from a borehole or well, you need to remove iron from the water.

How do you know when hardness needs to be removed? First of all, by changing the color of the products you use. Red spots appear not only from rust, but also from stains on cutlery. Even a child can notice yellow stains. In such water, tea takes a long time to brew, it becomes hard - rice and pasta do not boil, and if you pour boiling water into milk, sediment forms in flakes. It is recommended to use water from an iron-containing well only for watering onions and herbs!

The process begins at the filtration stage. First, the water is purified from sand, silt and other mechanical impurities. Then they begin to remove microparticles of rust and iron. The last stage is the removal of iron, fluorine, chlorine, and salts that are harmful to human health. Conclusions: The process of purifying water from pollution is a long process. Only a set of measures will ensure high-quality drinking composition. Let's take a closer look at the main methods of water deferrization. 1. Reagent filters. The technology of water deferralization includes treatment with reagents. Doses selected for home use: 5-10 g per 1 liter, depending on the iron content in the water. Using ultrasound, saturation is carried out for 3 hours. The method is more effective using the redox therapy method. In addition to iron, the solution is also used to remove acids. 2. Deironing cartridge Modern deferrization systems use reverse osmosis and nanofiltration to remove iron. The throughput of nanofiltration allows you to remove iron in one cycle up to 40 liters. Water, in combination with a catalytic filter, makes it possible to carry out disinfection and other treatment stages simultaneously. 3. Iron removal in parallel water treatment systems This is one of the most effective purification methods. Water after the iron removal system contains a small amount of organic compounds. The efficiency of the cleaning method in most cases reaches 95%.

4. Which filters to choose - reagent or reverse osmosis?

Iron removal from water by nanofiltration is relevant due to the simplicity of the design, their wide availability and reasonable cost. The disadvantage of this method is the fragility of the material. The service life is most often calculated at 4 months, after which regeneration will be necessary. Reverse osmosis devices consume 0.6 thousand liters as filtered impurities. during the period. With low rigidity, they will be in demand everywhere - in an apartment, in an industrial workshop, even in field conditions. Disadvantages include high cost - the unit price is several thousand dollars, and the need to manually replace cartridges. Regeneration of filters can take up to one and a half days. More precise figures depend on the volume of water consumed and the composition of the water resource.
