TAPU-MS,Nanofiltration membrane elements for municipal water application - Tapurim Series.
Product Presentation:
Organics, microbes, viruses and most of divalent and higher-valence metal ions can be filtered byTapurim Series NF element, while part of sodium, potassium, calcium, magnesium ions, etc . can beretained in the permeated water .
TAPU-MS Element has higher rejection rate of monovalent ions while maintaining a proper rejection rateof organics, which is applicable to the removal of organic and inorganic matters in midsalinity raw water .
Product Performance

Important information:
Before the membrane element leaves the factory, The dry membrane element has nopreservation solution, The wet membrane element has 1.0% sodium bisulfite (in winter, add 10%of propylene glycol antifreeze) as the preservation solution for storage treatment and usevacuum packaging .
Dry membrane elements should always be maintained wet after Soaking; when wetmembrane elements are not used for a long time, preservation solution is needed to soak theelements .
When the membrane element is used for the first time, it is recommended to flush it first for15-25 minutes at low pressure (not suitable for soaking or soaking overnight), and then flush itfor 60-90 minutes at high pressure (the water flow should not be less than 50% of the systemdesign water flow).
The permeate water and concentrated water within the first hour of the initial operation ofthe membrane element should all be discharged .
The operating limits and operational guidelines given in this technical information are partof the limitations of the three-year warranty on the membrane element .
The addition of any chemicals that may affect the membrane element during storage andoperation is prohibited, and Vontron Technology will not be liable for any consequencesarising from the use of such chemicals .
Please refer to the Product Manual for details on installation, commissioning, storage, andtransportation of membrane elements .
