ULP3113 800

Summary

Product identification

The ULP3113-800 is an Ultra Low Pressure (ULP Series) reverse osmosis (RO) membrane element, developed by VONTRON.

Application

This membrane is designed for treating low-salinity water sources such as:

• Tap water
• Well water
• Underground water
• Centralized water supply

It is applicable for:

• Residential water purifiers
• Hospital water purification devices
• Laboratory water purification devices

Product performance

Performance is tested under specified conditions:

• Testing Pressure: 100 psi (0.69 MPa)
• Temperature of Testing Solution: 25℃
• Concentration of Testing Solution (NaCl): 250 ppm
• pH of Testing Solution: 6.5~8.5
• Recovery of Single Element: 50 %

Note:

• Each membrane element may have ±15% variation in permeate flow.
• Rejection Rate may vary by ±2%.

Mechanical / hydraulic

Important Information

• Preservation:
  • Dry membrane elements leave the factory without preservation solution.
  • Wet membrane elements contain 1.0% sodium bisulfite (and 10% propylene glycol antifreeze in winter) as a preservation solution, and are vacuum packaged.
• Storage:
  • Dry membrane elements must always be kept wet after initial soaking.
  • Wet membrane elements, when not in use for a long time, require a preservation solution soak.
• Initial Usage:
  • It is recommended to flush the membrane element first at low pressure for 15-25 minutes.
  • Follow with a high-pressure flush for 60-90 minutes (water flow should be no less than 50% of the system design flow).
  • The permeate water and concentrated water produced within the first hour of initial operation must be discharged.
• Warranty: The operating limits and guidelines provided are part of the limitations for the three-year warranty on the membrane element.
• Chemicals: The addition of any chemicals that may affect the membrane element during storage and operation is prohibited.
• Documentation: Refer to the Product Manual for detailed information on installation, commissioning, storage, and transportation.
