Reverse Osmosis Filter

The need for proper water filtration system at home is clearly a worrying development because we face: current treatment facilities are timeworn and municipal sources of water supply loads of pollutants. Which water purification solution / water-filter system makes more sense to ensure clean water, clean and healthy for the family? The investigation of two water filtration and purification methods sheds light on this question.

> Reverse Osmosis Water Systems Inefficiency

In a reverse osmosis system (ROS) the water is passed through a sediment filter to remove sediment, dirt and algae. At a later stage the water passes through one or two to remove (depending on model), pre-filter, the volatile organic compounds from water. At a later stage, water is the reverse osmosis membrane that removes the minerals reached, lead, inorganic compounds, salts and more. TheThe water flows into a storage tank (4 gallons), which is an essential component of the system because the process of reverse osmosis is not instantaneous.

The small pores of the reverse osmosis membrane are restrictive, such organic compounds as salt and other minerals. This means that the reverse osmosis desalination is very effective in the production of mineral water and free water for use in print shops or photo. In order to eliminatehazardous chemicals and cleaning of drinking water, reverse osmosis alone, without an additional carbon filter is not sufficient, since the pores of the membrane block only large molecules such as salt.

Trace elements are locked

Activated carbon filters are only able to remove the smaller molecular substances and chemicals such as pesticides, herbicides and chlorine. Another disadvantage of reverse osmosis systems isthe removal of minerals that occur naturally and healthy. Trace elements will be blocked by the reverse osmosis membrane. These minerals make water tasty and serve as an important function of our body system.

Water without these trace minerals can actually be healthy for the body. Long-term consumption of demineralized water that can be harmful to the body and lead to mineral deficiency in the body. The waste water flows largelya reverse osmosis system is also problematic. The system generally wastes two 58 liters of water for every gallon of purified water that produces

Activated carbon filters more reliable

The process of water filtration with activated carbon filters is determined by the flow of water through a granular bed of sand or other suitable media (eg, different levels of carbon and media filters) from. The media remains the most solidMatter and requires the removal of all unwanted materials, allowing the water. The first stage of filtration removes most concentrated chemicals such as chlorine, trihalomethanes, the following steps to remove chemicals smaller and more elusive, such as herbicides or pesticides.

Chemicals adsorbed carbon

Granular activated carbon water filter systems clearly larger composite materials (eg salt) and retain traces of elements in it, and selectivelychemicals much smaller and more dangerous as chlorine and pesticides, that reverse osmosis systems remove not be removed. These water filters use a chemical adsorption (ie, add the attraction). In this way a large variety of dissolved contaminants are attracted and retained on the surface of carbon particles. In addition, these systems do not require heat or pressure, which makes them pretty cheap.

Pesticides, solvents and othervolatile organic compounds (VOCs) are not completely removed by reverse osmosis, because the membrane pores are blocked only the larger molecules. Only if an additional post carbon filter is used, these filters are effective and able to remove small molecular substances and chemicals such as pesticides, herbicides and chlorine.

Completion

Granular activated carbon filters are effective and valuable water treatmentDevices, but the consumer must maintain its boundaries. Must be the water pressure in a uniform and continues to be maintained for optimum performance needs to maintain, and evaluate the filter cartridge must be recommended by the manufacturer and / or the number of gallons the filter is changed.

The most effective water filtration and purification plant at home on the market today is a point of entry water filtration systemcombines two filtration technologies: granular activated carbon and KDF ® in which the water flows through several layers of GAC and KDF ® for maximum and cleaning.
