Is Reverse Osmosis The Best Water Filter For Your Home?

Commonly referred to as “RO” is a very powerful technology, it is not the best water filter for most homes or offices. Reverse osmosis is best suited to address the two issues for which it was originally designed:

Desalination of seawater or brackish water and / or

Reduction of very specific chemical contaminants.

Osmosis – is one of membrane separation methods solutions and suspensions into components based on passing through the semipermeable membrane of the volume of solvent molecules with a lower concentration of solutes.

In reverse osmosis, the water under pressure passes through the membrane from a more concentrated solution in a less concentrated, i.e. during the reverse osmosis liquid cleaned of solutes.

That is, the membrane is permeable only for particles whose size is equal to or smaller than the diameter of water molecules (i.e., oxygen, chlorine and other impurities permeable membrane).

Most reverse osmosis systems require a constant flow of water to clean and flush their membranes. This water is removed as waste water. Between 50-80% of the water entering the water treatment system can be disposed of as wastewater, something called concentrate (because the contaminants are concentrated in this stream of water).

The amount of water produced by the drinking system is called the recovery rate (the amount of good quality water recovered from the original water source).

So what is the best water filter for your home or office?

RO water purifiers are decent choice for house and office use, definitely not the best one.One of the best examples of this technology which offers:

· Easy installation,

· Faucet dedicated, (retrieve your refrigerator!)

· Minimum maintenance

· Visual indicator for filter change and

· Reduce harmful contaminants to the allowable limits of ANSI / NSF, without eliminating healthy minerals.

Advantages and disadvantages

Filters based on reverse osmosis water is removed from the chlorine ions, iron, heavy metals, insecticides, fertilizers, arsenic, etc, but also magnesium, potassium, calcium and other vital micro- and macronutrients.

The obtained reverse osmosis water has the degree of purification from impurities up to 98% (in industrial units – up to 100%). According to its properties, it is close to the glacial melt water. However, it should be borne in mind that the water purified by reverse osmosis, contains very little mineral salts.

For there is no single opinion about the benefit or harm of such water for health. Part of physicians believe that its use has a negative impact on the cardiovascular system, the normal operation of which depends on the intake of sufficient amounts of potassium and magnesium. Problem can be solved using additional cartridges, ensuring forced mineralization and recovery of the water structure.

A reverse osmosis filter as compared to the conventional free-flow filter that is considered to be expensive, but this is not always the case. If you are water meters, and you are concerned that three quarters of the water in the filter works to merge into the sewer, keep in mind that one liter of cold tap water in Moscow costs about 3 cents, and in comparison with the use of high-quality filter these costs are immaterial.

What does this all mean?

Reverse osmosis was originally invented as a means to desalt the sources of brackish water or sea water and should be used as a tool for which it is intended.

Contrary to its reputation, reverse osmosis does not eliminate 100% of all pollutants and reduction rates and certifications vary widely depending on the pollutant in question.

OI membranes can be damaged and destroyed by chlorine found in most municipal water supplies and therefore require pre-filtration of carbon.

Reverse osmosis water treatment systems are one of the most complicated types of systems on the market today and require pre-filters, storage tanks, pumps, drain connections and diligent maintenance and testing.
