E-MEM® FR series

Product introduction

FR (Fouling Resistant) series membrane is aromatic polyamide composite membrane element which is used in brackish water desalination, research and development from Hangzhou E-MEM Environmental Technology Co., Ltd. FR series membrane with its features of low operation pressure, high water flow, and high desalination rate. The unique anti-pollution patented technology is adopted to modify the membrane surface to change the charge and smoothness of the membrane surface, increase the hydrophilicity of the membrane surface, reduce the adhesion of pollutants and microorganisms on the membrane surface, reduce the pollution rate of membrane components, and extend the service life; At the same time, 34mil feed spacer design is adopted to reduce pressure loss and improve cleaning recovery. FR series are suitable for desalination of surface water, municipal water and industrial wastewater with a salt content of less than 8000ppm. They are mainly used for reuse of reclaimed water, boiler make-up water, circulating cooling water and other water treatment fields of various sizes. They are especially suitable for polluted water sources containing a small amount of organic matter.

matters needing attention

①. The data and information provided by HangzhouE-MEM Environmental Technology Co., Ltd in this sample are all obtained throughlong-term experiments, and we are convinced that these data and information areaccurate and effective. Customers are requested to use the product in strictaccordance with the design, use and maintenance requirements of the product andkeep relevant data records. Hangzhou E-MEM Environmental Technology Co., Ltdshall not bear any consequences arising from customers' failure to use andmaintain the products in accordance with the conditions provided by thissample.

②. The permeate flow listed in the table is the average value, and the deviation of single membrane element of permeate flow is±15%.

③. Before products leaving the factory, the drymembrane element has no protective liquid, while the wet membrane element isstored and treated with 1.0% sodium bisulfite (10% glycerin antifreeze added inwinter) solution and vacuum-packed.

④. Dry membrane elements should always be kept wetafter wetting. When wet membrane element is not used for a long time, in orderto prevent the growth of microorganisms, it is recommended to soak the membraneelement with protective liquid containing 1.0% sodium bisulfite (food grade)(prepared with RO production water).

⑤. For initial use of membrane elements, it isrecommended to flush first at low pressure for 15-25 minutes and then at highpressure for 60-90 minutes (water production not less than 50% of the system design).All production and concentrated water shall be discharged within the first hourof membrane element operation.

⑥. It is prohibited to add any chemical agentthat has an impact on the membrane element in storage and operation. If suchchemical agent is violated, Hangzhou E-MEM Environmental Technology Co., Ltdwill not bear all the consequences arising therefrom.
