Reverse Osmosis System(RO system) is the most effective treatment method.

Called reverse osmosis Reverese Osmosis RO, is known to the most effective and most modern water treatment methods. The so-called reverse osmosis system principle is in the raw water side pressure, so that pure water molecules through thin film (TFC Membrane) produces water, while will not penetrate the various impurities and harmful substances in waste water with the concentrate.

Ro System can effectively filter the water contained bacteria, viruses, chemicals toxic substances. Humans in the pursuit of pure drinking water in the process, from boiling, distillation, ion exchange, activated carbon filtration ...and so on, are unable to obtain the perfect water, only use reverse osmosis system (ro system) high penetration theory, the effective removal of 99% of the total dissolved solids in water quality (TDS), the purity of up to 1-10 ppm, applied to seawater desalination, dialysis water, hemodialysis, laboratory highly purified water.

By the ro system pure drinking water into the legal system is crystal clear, pure water does not contain pollutants, no bacteria, viruses, carcinogenic substances such as trihalomethanes, etc., to remove inorganic minerals, toxic heavy metals. Reverse osmosis pure water out of the legal system can perfect the use of the body, can be described as healthy water, still no law out of the water to his left out.

Reverse osmosis can effectively remove inorganic substances dissolved in water, organic matter, bacteria, pyrogens and other particles, still no law out of the water he was able to compare with.

To understand "reverse osmosis" theory before the first interpretation of "infiltration (osmosis)" concept. The so-called penetration refers to the semi-permeable membrane separating two solutions of different concentrations, in which the solute can not be through the semipermeable membrane, the concentration of water molecules with lower side reach the semi-permeable membrane by high concentrations of the other, until both sides of the concentration equal to date. No balance in before the party in the higher concentration to exert pressure gradually, then the aforementioned water will temporarily stop the move, this time the pressure required is called "osmotic pressure (osmotic pressure)", if the applied force greater than the osmotic pressure, the water movement in the opposite direction, that is, the flow from the high concentration of low concentration of one case, a phenomenon called "reverse osmosis."

Reverse osmosis purification effect can reach the level of ions, for the price from the (monovalent ions) of the exclusion (rejection rate) of up to 90% -98%, while the bivalent ions (divalent ions) up to about 95% -99% (You can prevent more than 200 Dalton molecular weight of the material through.)

Although more expensive reverse osmosis, reverse osmosis membrane pore size due to the general about l0A the following, which can eliminate bacteria, viruses and pyrogens dissolved ions, or even all, it is best to prepare safe drinking water in the preparation step of the road.

Because the film is only one billionth of a pore size cm. Only water molecules can penetrate the film.

Semi-permeable reverse osmosis membrane water treatment materials are commonly used in fiber plasma membrane (cellulosic), poly aromatic amines brew (aromatic polyamides), polyimide or polyfuranes so, as the structure of its spiral shape (spiral wound), hollow fiber type (hollow fiber) and tubular type (tubular) and so on. As these materials in the cellulose film has the advantage of high resistance to chlorine, but in alkaline conditions (pH ≧ 8.0) or bacterial conditions exist, life will be shortened. The disadvantage is a polyamide chlorine and chlorine poor tolerance to ammonia. As for what kind of material used is better, then there is no conclusion.

If you do not make pre-treatment before reverse osmosis osmotic membrane is prone to dirt accumulation, such as calcium, magnesium, iron and other ions, resulting in a decline in reverse osmosis function; some films (such as polyamide) easily destroyed by chlorine and chloramines, Therefore, activated carbon and reverse osmosis membrane softening before have such pre-processing.

That is why the first three channel filter requires regular replacement, and increase flushing RO membrane function.
