Reverse Osmosis Membrane Elements Technical Data
NF Series Membrane Elements
NF Series of nanofiltration membrane elements can achieve high permeate water and excellent desalination performance. Therefore, it is suitable for large-scale industrial and municipal water treatment systems. In use, it shows excellent ability to remove pesticides, viruses and bacteria. It has high ability to remove natural organic substances and medium ability to remove total hardness. Through innovative technology, the product has a stronger film surface, strong anti-oxidation performance, and the use of ultra- low pressure mode of operation can significantly improve the system and operation economy.

Note:
1.For the recommended design scope, please refer to the latest version of the technical manual, design guide, or consult with membrane technology experts. If the user does not strictly follow the operating conditions provided by the sample, Tianjin Justin Technology Co., Ltd will not bear all the consequences arising therefrom.
2.The average water yield listed in the table shows that the error of water yield of single membrane element in series is within (+10%). The difference between the minimum water yield and the nominal value of other series of single membrane elements is not more than 20% of the nominal value.
3.Wet membrane components are strictly tested before they leave the factory. They are stored in 1.0% sodium bisulfite solution. Then they are packed in vacuum and packed in cardboard boxes. The safe storage temperature of wet membrane components is 4-45℃.
4.RO production water to be discharged in the first hour of operation.
5.During storage and operation, it is prohibited to add any chemicals that affect membrane components. In case of violating the use of such chemicals, Tianjin Justin Technology Co., Ltd will not bear all the consequences arising therefrom.
