TAPU-LS,Nanofiltration memb rane e lements for munic i pal water application - Tapuri m Series.
Product Presentation:
Organics , microbes , viruses and most of metal ions with two or higher valence can be filtered by TapurimSeries NF element , while part of sodium , potassium , calcium , magnesium ions , etc . can be retained in thepermeated water .
TAPU-LS Element is designed primarily for removal of organics while keeping most of the monovalent ionsretained in the permeated water , and is applicable to removal of organics and inorganics from raw waterwith low salinity .
Application:
The production of drinking water , such as: municipalwaterworks , rural area drinking water projects , etc
Product Performance:
1、Operating pressure 70 psi (0 .48 MPa) Tested in mixed solution of NaCl , MgSO4 and CaCl2 Temperature at 25℃ pH 7.0 ± 0.5 Recovery rate at 15%.
2、Each membrane element may have ±20% variation of permeate flow .
3、TOC removal rate is more than 90 %.

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 .
