Description
Vontron ULP11‑4040 RO Membrane – Ultra‑Low‑Pressure 4″×40″
The Vontron ULP11‑4040 RO Membrane is an ultra-low-pressure (ULP) reverse osmosis element designed for municipal water, surface water, and low‑salinity applications. This high-performance RO membrane reduces energy costs while maintaining excellent water quality. With a standard 4″×40″ size, it fits most RO systems for domestic and light industrial use.
Key Features of Vontron ULP11‑4040 RO Membrane
- Ultra‑low pressure operation minimizes pump energy requirements.
- Typical permeate output of 2,700 GPD with 97.5–99% salt rejection.
- Standard 4″×40″ size ensures easy integration.
- Suitable for feedwater TDS up to 2,000 ppm.
- Robust operating limits: max 600 psi pressure, 45 °C temperature.

Why Choose the Vontron ULP11‑4040 RO Membrane?
Because it blends compact size with high capacity and efficiency, this membrane is a smart upgrade for systems treating municipal or low‑brackish water where energy cost and pump size matter. Its ultra-low-pressure design cuts operating cost and simplifies system design. Additionally, its proven brand and performance make it reliable for commercial installations.
Benefits of Using Vontron ULP11‑4040
This RO membrane ensures reliable, high‑quality water for domestic, commercial, and light industrial systems. It reduces operational costs, fits standard housings, and guarantees long-term performance. Perfect for retrofits and new installations alike.
Installation & Maintenance Tips
- Ensure pre‑treatment: feed silt density index (SDI) ≤ 5; free chlorine in feed < 0.1 ppm.
- On initial startup, flush new element: 15‑25 minutes at low pressure, then 60‑90 minutes at design pressure. Discard the first hour permeate.
- Monitor permeate flow and rejection: declining performance may indicate fouling, scaling, or damage.
- Clean according to manufacturer guidelines, observe pH limits (cleaning 2‑12).
- Store spares wet or in a protective solution (1% sodium bisulfite) if the system is idle.
