VONTRON FR11-4040 Membrane Element 

Brief Introduction:

FR11-4040 RO Membrane Element utilizes specialized manufacture technique that can improve the hydrophilicity, electric charge and roughness of its surface, thus reducing the breeding andadsorption of pollutants and microbes on membrane surface. 

FR series of fouling resistant membranes normally suitable for treatment of complex water sourcewith TDS less than 10000 ppm. It is mainly used for purification of surface water, mining wastewater, municipal reclaimed water, industrial waste water, RO brackish water, etc.

Size of Membrane Element：1.0 inch =25.4 mm

Notice: 

1.All data and information provided in this manual have been obtained fromlong-termexperiment by Vontron. We confirm the effective and accuracy of the data. We assume no liabilityfor any consequences of user’s failure in abiding the conditions specified in this manual in use or maintenance of membrane products. It is strongly recommended that the user shall strictly abide the designed use and maintenance requirements and keep relevant records.

2. The permeate value listed in the table is the average value. The permeate flowof single membrane element is tolerance not exceeding ±15% of the nominal value.

3. All wet-type membrane elements have been strictly tested before leaving the factory, andhave been treated with 1.0% sodium hydrogen sulfite (10% glycerin antifreeze required in winter) for storage purpose, then sealed with plastic bag in vacuum, and further packed in carton boxes.

4. The membrane used should remain wet after being used; In long term suspension, to prevent the breeding of microbes, soak the membrane elements with protective solution is highlyrecommended, the solution (prepared with RO filtered water) containing 1.0% sodiumhydrogensulfite (food grade).

5. Operate low pressure flushing for 15-25 minutes of first use, high pressure flushing for 60-90minutes when first use (Permeate flow no less than 50% of designed flow). Discard all thepermeate and concentrated water produced during the first one hour after system start-up.

6. During storage and operation period, it is strictly prohibited to add any chemicals that may be harmful to membrane elements. In case of any violation in adding chemicals, Vontron assumes noliabilities for any damages incurred.

7. Along with technical development and product renovation, all information will be subject tomodification without prior notification. Please keep notice the website of Vontron for any updates of the product.
