Vontron ULP22-8040 Membran Filtre (ULP22-8040)

ULP22-8040 Ultra Low Pressure Membrane Elements - ULP Series Product Presentation Application ULP Series Membrane Element can work with ultra-low pressure to re ach a water flux and rejection rate that can rival its common low-pressure counterpart. It can operate with 2/3 pressure of LP Series. ◎ Industrial pure water production, for example: electric power, steel, chemical industry, etc. ◎ Desalination of drinking water, for example: purewater, packaged water.

Operating Conditions & Limits Important information Maximum operating pressure psi(MPa) 600(4.14) 〇 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, add10%of propylene glycol antifreeze) as the preservation solution for storage treatment andusevacuum packaging. 〇 Dry membrane elements should always be maintained wet after Soaking; whenwet membrane elements are not used for a long time, preservation solution is needed to soak theelements. 〇 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 flushit for 60-90 minutes at high pressure (the water flow should not be less than 50% of the systemdesign water flow). 〇 The permeate water and concentrated water within the first hour of the initial operationof the membrane element should all be discharged. 〇 The operating limits and operational guidelines given in this technical information arepart of the limitations of the three-year warranty on the membrane element. 〇 The addition of any chemicals that may affect the membrane element during storageandoperation is prohibited, and Vontron Technology will not be liable for any consequencesarising from the use of such chemicals. 〇 Please refer to the Product Manual for details on installation, commissioning, storage, andtransportation of membrane elements.
