Currently, the most favorable water purifier RO reverse osmosis and ultrafiltration unit, commonly referred to as pure water and the water purifier. What are the differences between the two is what? The average consumer can be distinguished from the following two aspects.
any difference between pure water and the water purifier? Four aspects tell you (Photo from Internet)
First, the technical
The biggest difference between reverse osmosis and ultrafiltration membrane technology is that the filtration accuracy.
Reverse osmosis: means applying a high osmotic pressure than the ambient pressure at the inlet side of the membrane, allowing only certain components of the solution and water selective permeation of other substances is impermeable trapped in the film surface process, referred to as the RO, which filtration accuracy of 0.0001 micron.
UF: In a pressure difference as the driving force, separating the molecular weight range of several hundred to several million, membrane pore size from about 0.001 to 0.2 micron physical screening process, referred to as the UF, which was filtered to 0.001 micron.
Second, the structure
of pure water: booster pump requires a power source, the storage tank, typically five filters. The first stage of the filter, the second and third stage is activated, the fourth stage RO reverse osmosis membrane is used in aerospace technology, the fifth stage is refined activated carbon is mainly used to improve the taste.
purifier: no motor, does not require power, by hydraulic drive filtered, stainless steel tube body, high temperature stainless steel, corrosion-resistant, can adapt to changes in environmental temperature.
Third, the function
water machine: impurities, rust, silt, colloids, bacteria, viruses, and harmful radioactive particles, organic substances, fluorescent substances, pesticides removed , it can also get rid of heavy metals and alkaline water; but it will also get rid of trace elements beneficial to humans.
water filter: filter out impurities in tap water, rust, some bacteria, viruses, colloids, etc., filtered water retention useful trace elements pairs.
Fourth, the shortcomings
of pure water: water system of pure water in the process will produce waste.
purifier: the role of heavy metals and alkaline water is not great.
is the difference between the above four aspects of the water and PurifierCompare, hope to have some reference to help everyone to buy oh!
