Vontron SW4040HR

P4 830

SW series of aromatic polyamide compound membrane element developed by Vontron Membrane Technology Co., Ltd. is applicable to desalination of seawater. By optimizing the structure of membrane element, the SW series increases the permeate flow, and requires fewer elements for same permeate flow. It is characterized by low operating pressure, low investment in equipment, excellent rejection rate and reliable performance.

Vontron SW4040HR Industrial RO Membrane

The Vontron SW4040HR RO Membrane is a high‑performance, industrial‑grade reverse osmosis element designed for demanding environments such as seawater or high‑salinity brackish water feed. It features a spiral‑wound configuration with a large active area of ~8.8 m² (~95 ft²) and a typical permeate output of 1,600 GPD (~6.1 m³/day) under test conditions.
Because it achieves a salt rejection rate of 99.8%, it offers outstanding purification for high TDS inputs.
The SW4040HR is built with robust materials and rated for high pressures (up to ~8.3 MPa / ≈1,200 psi) for demanding desalination tasks.

Key Features

  • High salt rejection (~99.8%) — suitable for seawater or high‑brine feed.
  • Large active area (~8.8 m²) inside a standard 4″×40″ housing — supports higher throughput.
  • Robust pressure rating — max allowed pressure up to ~1,200 psi (8.28 MPa), which allows industrial use.
  • Wide pH and chemical tolerance — operational pH range 2‑11, cleaning range 1‑13.
  • Seawater‑qualified design — excellent for systems treating saline or high‑TDS water.

Technical Specifications

  • Model: SW4040HR
  • Active Membrane Area: ~95 ft² (≈8.8 m²)
  • Typical Permeate Flow: ~1,600 GPD (~6.1 m³/day) under standard test condition (32,000 mg/L NaCl, recovery 8%)
  • Stable Rejection Rate: 99.8% (under test)
  • Maximum Operating Pressure: ~1,200 psi (~8.28 MPa)
  • Maximum Feed Flow: ~3.6 m³/h (~16 gpm)
  • Maximum Feed Temperature: ~45 °C
  • Required Feed Conditions: SDI ≤5, free chlorine <0.1 ppm

Why Choose the Vontron SW4040HR RO Membrane?

For industrial or commercial applications that demand serious water purification, the Vontron SW4040HR is an excellent choice. Because it handles high salinity, offers high rejection and high flow in a standard 4″×40″ format, you avoid oversized vessels or custom arrangements. Moreover, thanks to its robust design and high-pressure rating, it performs reliably in harsh feed conditions. Additionally, when pre‑treatment is properly maintained, this membrane delivers consistent, high-quality permeate and longer service life — ideal for desalination systems, high‑TDS feed water, and industrial water reuse settings.

Installation & Maintenance Tips

  1. Ensure solid pre‑treatment: feed water SDI ≤5, free chlorine <0.1 ppm, temperature ≤45 °C.
  2. On first use, flush the new element at low pressure (~15‑25 min), then at full design pressure for ~60‑90 min before regular operation. Inzton
  3. Monitor performance: if permeate flow or salt rejection drops, inspect for fouling, scaling or membrane damage.
  4. Follow periodic chemical cleaning according to feed‑water chemistry; ensure pH stays within allowable cleaning range (1‑13).
  5. For storage or standby, maintain the element wet in a protective solution (e.g., 1 % sodium bisulfite) to prevent microbial growth.
