On November 2, the AQSIQ and the National Standards Commission released the national standard "Limit value of water efficiency and water efficiency of reverse osmosis water purifier." This standard specifies the most stringent water resources management system The red line for water efficiency control will come into effect in November 2018.
With the improvement of living standards, people pay more and more attention to the quality of drinking water, water purifier demand and consumption also will continue to grow.Which reverse osmosis water purifier due to the high quality of water, the current market share has reached the market share 60%, nearly 4000 production enterprises, the annual sales of more than 1000 million units of these products to reverse osmosis membrane as the main purification components, through the multi-stage filtration to achieve the purpose of purification, while producing some concentrated wastewater.According to the survey, the current market close 40% of domestic reverse osmosis water purifier water production rate of less than 20%, resulting in huge waste of water.National Standards Commission to promote the improvement of water efficiency of such products to promote the development of reverse osmosis water purifier water efficiency standards.
According to reports, the standard on the one hand provides for the detection and calculation of water efficiency methods, on the other hand the water efficiency is divided into five, and set the red line of water purification rate of water, water efficiency rating of 5 that is 35%. Through the setting of water efficiency limit, at least 30% of high-water consumption products will be eliminated and the annual water saving amount is estimated to exceed 100 million cubic meters. According to the survey, the average efficiency of water purifier is less than 20% Double, reaching 40% .At the same time, the standard set of advanced water-saving value, can lead the industry to improve water efficiency.Water efficiency standards of reverse osmosis water purifier 2 that water-saving evaluation value of 55%, as leading the efficient water-saving products Advanced indicators, will encourage enterprises to improve technology, by improving the overall quality of products to achieve higher water efficiency.
Currently released water efficiency standards a total of eight, namely, toilet, tap, washing machine, water purifier, shower, urinal, squatting pan, toilet flushing valve, faucet, urinal, squatting pan and toilet flush Valve plans to be revised, two national standards for water efficiency of dishwashers and rotary nozzles are being developed.
On September 13, 2017, the National Development and Reform Commission, the Ministry of Water Resources and the General Administration of Quality Supervision, Inspection and Quarantine jointly released the Measures for the Administration of Water Efficiency Labeling. The compulsory national standards for water efficiency are the basis and foundation for the implementation of the water efficiency labeling system. In the future, The standard implementation of the water purifier water efficiency labeling, labeling enterprises by affixing water efficiency, self-declared reverse osmosis water purifier water efficiency rating and the main indicators of water to accept the supervision of the market and consumers through the implementation of water efficiency labeling system will be Will effectively improve the effectiveness of the implementation of water efficiency standards.It is estimated that the implementation of water efficiency labeling can save 6 billion tons per year.
