Please message us before placing your order. Thank you!

Highlight of SW11-2540
Sea Water Desalination RO Membrane Elements - SW Series
Product Presentation Application
SW Series is used for seawater desalination. It can improve permeate flow by optimizing membrane
element structure. It has the features of a high rejection rate, stable performance, low operating cost, and

small equipment investment. It can be used to obtain qualified drinking water from seawater.

Application
◎ Seawater desalination.
◎ Concentration of high-concentration materials, for
example: pharmaceutical materials, food and beverage materials, etc.

Suitable for standard 2.5"*40" Fiberglass and SST membrane housings

Important information

• Before the membrane element leaves the factory, The dry membrane element has no preservation 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 use vacuum packaging.
• Dry membrane elements should always be maintained wet after Soaking; when wet membrane elements are not used for a long time, a preservation solution is needed to soak the elements.
• When the membrane element is used for the first time, it is recommended to flush it first for 15-25 minutes at low pressure (not suitable for soaking or soaking overnight), and then
  flush it for 60-90 minutes at high pressure (the water flow should not be less than 50% of the system design water flow).
• The permeate water and concentrated water within the first hour of the initial operation of the membrane element should all be discharged.
• The addition of any chemicals that may affect the membrane element during storage and operation is prohibited, and Vontron Technology will not be liable for any consequences arising from the use of such chemicals.
• Please refer to the Product Manual for details on installation, commissioning, storage, and transportation of membrane elements.
