  Core Tip: water industrys first national mandatory standards --GB34914-2017 "reverse osmosis water purifier water efficiency limit value and water efficiency rating of" national standards (referred to as "water efficiency standards") officially released, and [123 ] water industrys first national mandatory standards --GB34914-2017 "reverse osmosis water purifier water efficiency limit value and water efficiency rating of" national standards (referred to as "water efficiency standards") officially released, will begin early next year implementation. This means that the state will be forced to means of production of reverse osmosis water purification products, sales made water-saving requirements. This is the second health and safety, product quality, the state of the reverse osmosis water purifier has proposed a requirement.

   Recently, the water industrys first national mandatory standards --GB34914-2017 "reverse osmosis water purifier water efficiency limit value and water efficiency rating of" national standards (referred to as "water efficiency standards") officially released and it will begin in early next year. This means that the state will be forced to means of production of reverse osmosis water purification products, sales made water-saving requirements. This is the second health and safety, product quality, the state of the reverse osmosis water purifier has proposed a requirement. This standard will have a profound impact on the water industry, water purifier manufacturers Forced technological innovation, improve the performance of water-saving reverse osmosis water purifier produced.

鍑€姘村櫒 Reverse osmosis water purification because of its technical characteristics of cross-flow filtration, the concentration of water must be discharged. Before "water efficiency standards" release, the industry usually "waste than the" nominal term for water utilization. Then, "water efficiency standards," called "water efficiency", with the industry original generic "waste than the" what difference does it make?

   1, the test conditions and specifications of different

   "Wastewater ratio "is the nominal various manufacturers themselves, have not been rigorously tested, is just a rough proportion. And after the "water efficiency" requires strict accordance with the provisions of the "water efficiency standard" test conditions for testing to nominal.

   2, different nominal request

   "waste ratio" is the nominal factory itself, there is no national requirements must be marked. The "water efficiency" identifies After the standards, each home water purifier must be affixed prominently labeled. .

鍑€姘村櫒 3 represent different forms

   "waste ratio" represents a ratio manner as the preparation of 1 part water, three discharge concentrated water, waste water ratio of 1: 3 represents . and"Water efficiency "represents the percentage of places, such as water efficiency of 60%, then the raw water system from the clean water of 60%, the discharge amount of concentrated water 40%

   4. Meaning different

   [ 123] water is efficient water use efficiency, is the ratio of the total amount of water consumed by the obtained clean water, flushing water purifier consumption is to be calculated, including water.

   the "waste ratio" look only at a reduced water flow and water flow of the discharged water during a reverse osmosis membrane system, the consumption of flushing water purifier, no matter how many are not included therein, and therefore, it does not the reaction can be water use efficiency, but only one operating parameter of a reverse osmosis water purification unit.

   5. water has the lowest effective limit requirements, the "waste ratio" is not 搴熸按姣? src= [123 ] "water efficiency standards", water efficiency less than 35% (five) of reverse osmosis water purification unit, prohibiting production and sales. the "waste ratio" is not a predetermined minimum value.

   in after the "water efficiency standards" release, reverse osmosis water purification machines, the manufacturers and distributors, both above concepts deal with a converter on an understanding and avoid misunderstandings and unnecessary trouble.

   Mechanical and Electrical IAQ real commitment to a healthy home environment, you create a constant temperature and humidity, oxygen-rich, clean, healthy home comfort system gives you a higher quality of life.
