March 7 news, has been Wastewater reverse osmosis water purifier is always restricting the development of product, and only water-saving products to improve capacity and reduce the rate of waste water to be able to give full play to the advantages of reverse osmosis, so that better product development, while giving consumers with more excellent products. To solve this problem today by the China Household Electrical Appliances Research Institute of testing technology, smart home research center jointly organized the "first passed the mandatory national standards" reverse osmosis water purifier water efficiency and water efficiency rating limit value "(to be issued) detection of water purification products conference "held in Beijing, experts discussed hot issues on the current water purifier industry, and released a list of related products.
Our country is a lack of water resources in the country, with the development of industry, water continues to be contaminated. According to related statistics, at present, the countrys water plant a total of more than 4,000 daily supply of 60 million tons of tap water is more than 400 million urban residents in the county. Due to the different water sources, water quality residents of the home are not the same. In some areas such as water quality is very hard, alkaline water is great; some areas affected by the impact of illegal discharge of industrial, water sources to varying degrees of organic or heavy metal pollution; some areas drinking water pipelines due process of secondary pollution, resulting in excessive microorganisms.
At present, the best way to improve water quality, it seems is to install a home water purifier. While the current water purification technology, since the reverse osmosis water purification unit (RO unit) of the filter pore size is extremely small, a variety of viruses, bacteria, heavy metals, soluble solids, organic contamination and metal ions hardly pass reverse osmosis membrane, Therefore, reverse osmosis water purifier (RO machine) is the best solution to solve all the problems of water quality.
However, due to the different techniques of reverse osmosis water purification treatment, will produce a concentrated portion of the water while obtaining drinking water, the actual use, various mixed products, indeed some water purifier It is a waste of water. The issue has attracted attention is also water purifier industry, related businesses are also trying to improve their own technical strength, and strive to improve the efficiency of water purification machines, so that consumers spend more water-efficient water purifier.
for water efficiency in water purification equipment, water purification Chinese Academy of household appliances Performance Research and Testing Center recently launched the "RO water purifier water efficiency and water efficiency rating limit value" test. According to the national standard mandatory "reverse osmosis water purification efficiency limit water and water efficiencyRating "for Approval, the water purifier of the efficiency rating is divided into 6, wherein the predetermined level of water aquaculture net 5 in the water purifier water purifier efficiency rating was limited values, that is to say all the net rate of aquatic RO water purifier must be 鈮?5%; water aquaculture net 2 in a predetermined stage water purifier saving efficiency rating evaluation value was water purifier, that is effective to achieve the level of water 2 or more of the water purifier can be called a water-saving type water purifier; water aquaculture net can be regarded as the leading value of the water purifier efficiency should be not less than 75%.
