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, 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 operating limits and operational guidelines given in this technical information are part
of the limitations of the three-year warranty on the membrane element.
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.
