Reverse Osmosis: Benefit or Harm, Principle and Characteristics
The quality of water purification today can be ensured at the highest level. For this purpose, special equipment is used. Are filters such as Benefit or harm done by such a device popular? Features and its principle of operation should be considered before purchase.
Membrane cleaning method is the basic principle of reverse osmosis. Benefit or harm such a device will help to understand the reviews of experts. Osmosis is a membrane method for purifying water, during which the solution is divided into specific components.
Osmosis allows the suspension molecules to pass through the semipermeable membrane in the direction of the volume with a higher concentration of dissolved substances. This method is widely used in water purification. The essence of reverse osmosis is the opposite effect.In this case, the liquid passes under pressure from a solution with a higher concentration to a less concentrated medium.
Reverse osmosis allows you to purify water from substances that are dissolved in it. Substances with a diameter equal to or smaller than the size of water molecules (for example, oxygen, chlorine) are able to pass through the membrane of this filter. Mankind began to actively apply this principle of cleaning in the 70s of the last century. Subsequently, the production technology allowed to produce filters of this type for domestic use.
The special characteristics of reverse osmosis should be considered. Benefit or harm this device will become clear after a comprehensive study of the issue. The water that passes through the membrane under pressure is characterized by a high degree of purity. Its main indicators equate to the meltwater of glaciers. It is known to be the most useful, eco-friendly source of fresh water in the world.
Today, reverse osmosis is the most effective means for filtering water. The presented systems are used for both domestic and industrial purposes.Reverse osmosis has been recognized worldwide.
This is a molecular filter that can provide a high degree of consumer protection from adverse components in water. After passing through the membrane, the liquid becomes crystal clear. Virtually no other method can compare with the quality of reverse osmosis filtration today. The membrane retains viruses, bacteria, heavy metals, hardness salts, iron and other components unfavorable to the human body.
Special attention is given to the design of reverse osmosis. Does this device benefit or harm? This question interests many buyers of filtration systems.
The design includes several cartridges. They contain filters and a membrane. The system also includes a tank. Purified water enters it. Tank capacity can be from 8 to 12 liters. The choice depends on the number of residents in the house or apartment.
The kit can be easily installed under the sink. Although it will need to provide enough free space. Before reaching the membrane, the water is pre-cleaned. It passes through cartridges with special fillers.They contain particles of sand, chlorine, metal, etc.
After the water passes through the membrane, it enters the storage tank. More than 75% of all the liquid that has come to it with a concentration of various impurities is drained back into the sewer system. After the storage tank, the water goes through one or two additional purification steps. After that, it can be used for drinking or cooking.
Water after reverse osmosis is distinguished by its special characteristics. The benefits and harms of such installations are invariably subject to disputes. Specifications are impressive even skeptics. This device has a resource of 4 thousand liters. At the same time there are constructions on sale that can clean up to 15 thousand liters of water.
The system capacity ranges from 170 to 250 liters per day. This allows you to get enough water that can be used for drinking and cooking. The duration of the operation of the system between filter changes depends on the number of consumers. Thus, a family of 4 people can use reverse osmosis for 2 years, if the resource of the system is 5 thousand liters.
Replacement of filter elements must be made in a timely manner. Pre-cleaning cartridges are changed every six months. You also need to pay attention to finishing designs. These filters need to be changed once a year. The replacement procedure is straightforward. No need to use special equipment. Flasks with cartridges are easily unscrewed using the key that comes in the kit.
Reverse osmosis filters have a lot of advantages. Harm or benefit bear such cleaners? The degree of cleaning of such a system is 98%. Domestic filters are not able to perform filtration with a greater degree of quality. Only industrial units are able to purify water by 100%.
Such harmful components as heavy metals, chlorine, insecticides, arsenic, various chemical compounds are removed from the water. Also harmful microorganisms, bacteria, fungi are removed from the liquid.
By its qualities, the presented water is equal to thawed. This is an environmentally friendly substance that can not harm the body. It is especially important to apply high-quality water purification in areas where there are large production facilities, agricultural land and other industrial facilities. Various harmful substances enter the soil and water bodies.Reverse osmosis is also necessary for people who use water from wells.
Opinions of doctors about the harm or benefits of reverse osmosis are divided. The fact is that molecular membranes remove from the water almost all minerals that the body needs for normal functioning. These substances include, first of all, magnesium, calcium, potassium. They also cannot overcome membrane cells.
Some doctors argue that such a filter can have a negative effect on the work of the cardiovascular system. Especially negative impact on her lack of potassium and magnesium.
Today this problem is almost a thing of the past. Almost all systems come complete with an additional mineralizer. If desired, it can be purchased separately. This additional element allows you to restore the desired structure of the liquid, providing it with the necessary level of useful minerals.
Features of the system
Special requirements differ reverse osmosis with a mineralizer. The harm or benefit of such a device can be considered by buyers first.But then they pay attention to its practicality.
Some buyers claim that reverse osmosis is an expensive cleaning system. At the same time, it is precisely their exploitation that is distinguished by great expenses. More than 75% of water is not used, but is discharged into the sewer. However, it should be noted that this is a low-quality liquid, which is not advisable to apply even in the process of bathing or washing.
The cost of 1 liter of water does not exceed a few kopecks. Therefore, it is not necessary to talk about large additional costs for system maintenance. Additional costs for installing special equipment that will maintain the required water pressure may increase costs when installing the system. This indicator should not be lower than 3 atm. Therefore, pumps are installed on the upper floors.
The cost of water purification
Some buyers claim that the high cost in the end result is a reverse osmosis water. The benefits and harms of this liquid depend on the set of components with which the mineralizer enriches it. Save on the acquisition of such equipment is not worth it. Only proven manufacturers can ensure a harmonious balance of minerals that enrich the purified liquid.
The system itself can be purchased at a price of 7-10 thousand rubles.Replacement cartridges held 2 times a year. Their cost can be 3-5 thousand rubles. The total cost of such a system will be maximum 15 thousand rubles. In a year, a family of 4 consumes about 3 thousand liters of water. The cost of 1 liter of water in this case will be about 5 rubles. In this case, bottled water will cost about 15-20 rubles per liter. Installation of reverse osmosis saves about 3 thousand rubles. in year. In this case, the water can be dialed directly from the tap, which will be installed on the sink in the kitchen.
Knowing the benefits and harm of water after reverse osmosis, you can make the right decision about the need to purchase such an installation. Many doctors agree that high-quality systems are not only not harmful to health, but also significantly reduce the degree of negative impact of environmental factors on the human body.
Acquire reverse osmosis should be only from trusted vendors. In specialized stores you can find filters that are made by foreign and domestic companies. Experts recommend purchasing Russian-made products. Such plants are designed for the quality of water that is supplied to consumers in our country.
High quality known reverse osmosis systems of companies "Aquaphor", "Barrier". They can be purchased at prices ranging from 6 to 10 thousand rubles. In this case, you can choose a complete set that best suits the characteristics of operation. The company "Atoll" applies when creating their products components made in the USA. This significantly increases the cost of reverse osmosis. It can be purchased at a price of 12-15 thousand rubles.
Recommendations of specialists
