HP 1812 80

Summary

Product identification

The HP1812-80 is a Helixfil Series Reverse Osmosis Membrane Element developed by Vontron.

Application

This RO element is designed for treating low-salinity water resources such as tap water, well water, centralized water supply, and underground water. It operates under extra low pressure and is suitable for:

• Residential water purifiers
• Hospital and laboratory water purification devices

Product performance

Performance is tested under specific conditions:

• Testing Pressure: 60 psi (0.41 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: 60 %

Under these test conditions, the HP1812-80 membrane element provides:

• Permeate Flow: 80 GPD (0.3 m³/d)
• Rejection Rate: 99%
• Min. Rejection: 98%

Note:

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

Mechanical / hydraulic

The physical dimensions of the element are:

• A: 298 mm
• B: 46 mm
• C: 17 mm
• D1: 15 mm
• D2: 20 mm

Important information

• Preservation:
  • Dry membrane elements have no preservation solution from the factory but must always be maintained wet after soaking.
  • Wet membrane elements contain 1.0% sodium bisulfite (with 10% propylene glycol antifreeze added in winter) as a preservation solution and are vacuum packaged.
  • If wet membrane elements are not used for a long time, they require preservation solution soaking.
• Initial Use:
  • Flush the membrane for 15-25 minutes at low pressure (not suitable for soaking overnight).
  • Subsequently, flush for 60-90 minutes at high pressure (water flow must not be less than 50% of the system design flow).
  • Permeate water and concentrated water produced during the first hour of initial operation must be discharged.
• Chemicals: The addition of any chemicals that may affect the membrane element during storage and operation is prohibited.
• Warranty: The operating limits and guidelines provided are part of the limitations for the three-year warranty.
• Further details: For comprehensive information on installation, commissioning, storage, and transportation, refer to the Product Manual.
