Notice:
1. The permeate value listed in the table is the average value. The permeate flow of single membrane is tolerance not exceeding ±15% of the nominal value.
2. All the membrane elements have been strictly tested before leaving the factory, and have been treated by dry technology, then sealed with plastic bag, and further packed in carton boxes. In long term suspension, to prevent the breeding of microbes, soak the membrane elements with protective solution is highly recommened, the solution (prepared with NF permeate water) containing 1.0% sodium bisulfite (food- grade).
3. Discharge all the NF permeate and rejected water produced during the first one hour after system start-up.
4. During storage time and operation period, it is strictly prohibited to added any chemical medicament that may be harmful to membrane elements. In case of any violation in adding chemical medicament, we assumes no liability for any damages incurred.
5. Along with technical development and product renovation,all information will be updated at any time. Please keep notice our latest information of the product .
