VONTRON LP22-8040 PRO Low Pressure RO Membrane Elements- LP Series.
Product Presentation:
Low Pressure Series is primarily used in desalination of brackish water. This series features low operating pressure, high permeate flow and rejection. It has high performance in rejecting soluble salt, TOC and SiO2 , and can be widely applied in pure water production in electricity and electronic industries.
Application:
Industrial pure water production, for example: electric power, steel, chemical industry, etc.
Desalination of drinking water, for example: purewater, packaged water.
product Performance:
1.Operating pressure 225 psi (1.55 MPa) 2000 mg/L NaCl solution Temperature at 25℃ pH 7.0 ± 0.5 Recovery rate at 15% .
1-2.Each membrane element may have ±15% variation of permeate flow.
Operating Conditions & Limits:

Maximum inlet flow rate m3/h --------17
Maximum concentration of free chlorine mg/L------- 0.1
Maximum pressure drop per element psi(MPa)-------- 15(0.1)
Allowed pH range for feedwater in operation -------2-11
Allowed pH range for chemical cleaning ------1-13
Maximum feedwater flow SDI15------ 5
Important information:
Before the membrane element leaves the factory, The dry membrane element hasnopreservation 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; whenwet membrane elements are not used for a long time, preservation solution is neededtosoakthe elements.
When the membrane element is used for the first time, it is recommended to flushit first for 15-25 minutes at low pressure (not suitable for soaking or soaking overnight), andthenflush 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 operationof the membrane element should all be discharged.
The operating limits and operational guidelines given in this technical informationarepart of the limitations of the three-year warranty on the membrane element.
The addition of any chemicals that may affect the membrane element during storageand operation is prohibited, and Vontron Technology will not be liable for anyconsequences arising from the use of such chemicals.
Please refer to the Product Manual for details on installation, commissioning, storage, and transportation of membrane elements.
