VONTRON   SW8040XHR-400 Membrane Element

Brief Introduction:

SW series of sea water aromatic polyamide RO element developed by VONTRON for seawater desalination.  This  series  of elements  have  the  characteristics  of low  operating  pressure,  low equipment   investment,   good   desalination   performance   and   stability.   Among   them,   the SW8040XHR-400 have the highest desalination rate of 99.85%, which ensure that drinking water can be produced from seawater through one pass RO system.

SW series membrane elements are generally suitable for the treatment of seawater and brackish water with high concentration. It can be used for seawater desalination, desalination of brackish water  with high  concentration, boiler  replenishment  water in power  plants, wastewater  reuse, concentration and recovery of high value-added substances such as food and pharmaceuticals, etc.

Size of Membrane Element：1.0 inch = 25.4 mm

Notice:

1.All  data  and  information provided  in  this  manual  have  been  obtained  from  long-term experiment by Vontron. We confirm the effective and accuracy of the data. Vontron assumes no liability for any aftermath caused by user’s failure in abiding by the conditions specified in this manual in use or maintenance of membrane products. It is strongly recommended that the usershall 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  flow of single membrane element is tolerance not exceeding ±20% of the nominal value.

3.All wet-type membrane elements have been  strictly tested before leaving the factory, and have 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  highly recommended, the solution (prepared with RO filtered water) containing 1.0% sodium hydrogen sulfite (foodstuff-purpose).

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

6.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, Vontron assumes no liability for any damages incurred.

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