   [hyperlink] home reverse osmosis water purifier net As the water purifier can remove the water of harmful impurities, high removal efficiency, won a large number of markets. But the reverse osmosis the proportion of waste water discharge water purifier is generally 1: 2 (pure water: waste water), that is to say, purify one liter of pure water, which needs to discharge 2 liters of tap water is difficult for many consumers! to accept that there is a reverse osmosis water purifier "waste water", a serious waste of water! is this really true?

Introduction of reverse osmosis water purifier

   is a reverse osmosis water purifier a kind of a pressure higher than the osmotic pressure as a driving force, using a selective membrane permeable only selected water impermeable solute permeability, the process water from the water molecules of the solute separation. Reverse osmosis water purifier [1] is the main principle of reverse osmosis water treatment machines. General tap water conductivity through the RO membrane filter after 5渭s / cm (RO membrane filtration effluent water conductivity = conductivity 脳 desalination rate, generally inlet a reverse osmosis membrane desalination rate can reach 99% or more, 5 years guarantee operation above 97% required for relatively high conductivity water, 2-stage reverse osmosis may be employed, through simple processing, electric conductivity can be less than 1渭s / cm), in line with national standards laboratory three water. And then through an ion exchange column atomically loop filter, the water resistivity can reach 18.2M NaN, more than one water standards National Laboratory.

The technical principle of reverse osmosis water purification

   It is mainly used in the reverse osmosis membrane technology. It works by applying a certain pressure on the water, so that water molecules and mineral elements by a reverse osmosis membrane in a plasma state, and most of the inorganic salts dissolved in water (including heavy metals), organic and bacteria, viruses and the like can not penetrate through the reverse osmosis membrane, so that the permeated water and concentrated pure water can not penetrate through strictly separated; only the reverse osmosis membrane pore size of 0.0001 microns, the virus generally 0.02-0.4 m in diameter, the diameter of the common bacteria 0.4 -1 micron, so you can rest assured that bold to drink in pure water springs flowing.

   The soA case divided into a manual type (also economic), automatic type, but differs in that the water for backwashing aspect, economical use of water for backwash manual valve. Meanwhile, according to the characteristics of pure water used further divided into type hood and hood lower mold, the same action.

   is in operation water effluent why

   The core member

   of pure water is a reverse osmosis membrane is actually process a liquid concentrate, the amount of salt water in the course of working with water through the reverse osmosis membrane surface continue to increase, the osmotic pressure of water increases constantly. When the osmotic pressure of the booster pump increases, the water can not pass through the reverse osmosis membrane water purification inflow end. Also due to the increasing concentration of minerals in water, a number of sections substance (such as calcium carbonate, calcium sulfate, silicon) will be deposited in the surface of the reverse osmosis membrane, the reverse osmosis membrane pores and plug, resulting in decreased reverse osmosis membrane and desalinated water production rate (reverse osmosis membrane the ability to remove the inorganic salts in water) drop. Work in process water for the above phenomenon to be avoided, all of the applications in the reverse osmosis membrane has a ratio of water can be made of the product water, called "recovery."
