   State Administration of Quality Supervision, Inspection and Quarantine, the National Standardization Management Committee issued a "reverse osmosis water purifier water efficiency limit value and water efficiency rating of" national standards (hereinafter referred to as "standard"), to implement the most stringent water management system , draw a red line strict control of water use efficiency, and will be implemented in November 2018. ,

   At present, reverse osmosis water purifier market share has reached 60% of sales, manufacturers nearly 4000 year sold more than 10 million units. Such products to a reverse osmosis membrane element as the main purified by multi-stage filtration, to purify the purpose, while producing partially concentrated wastewater. According to the survey, the current market rate of net water aquatic nearly 40% of home reverse osmosis water purifier (hereinafter referred to as "water-efficient") less than 20%, resulting in a huge waste of water resources. National Standardization Management Committee to promote these products to enhance water efficiency, and promote the development of reverse osmosis water purifier water efficiency standards.

   "standard" aspect provides for detection and calculation of efficiency of water, on the other hand 5 into the water efficiency, and red set water aquaculture net rate, i.e. 5 water efficiency limit value 35%. By setting the limit value of the water effect, will eliminate at least 30% of the high water consumption products, preliminary estimates annual water over 100 million cubic meters. According to the survey, the average efficiency of water purification machines less than 20%, the average is expected to double after the "standard" implementation of more than 40%. "Standard" set up advanced water-saving value, water efficiency improvements can lead the industry. "Standard" in the Level 2 evaluation value that is 55% water saving, water-saving and efficient as leading indicators advanced products, encourage enterprises to improve technology, improve product quality through water to reach higher efficiency.
