Product Description
High-Efficiency Reverse Osmosis Membrane for Low-Pressure Water Treatment
The industrial-grade Ospura ULP-4040 (Ultra Low Pressure) reverse osmosis membrane is an advanced spiral-wound element measuring 4" in diameter (99 mm) and 40" in length (1016 mm). Constructed from a premium polyamide thin-film composite membrane material and encased in a durable fiberglass-reinforced epoxy outer wrap (FRP), it provides exceptional structural stability and long-term operating reliability. The ULP series delivers a high nominal salt rejection rate of 99.0% under ultra-low operating pressure (tested at just 150 psi / approx. 10 bar), achieving a high permeate flow rate of 2,500 GPD (9.5 m3/day).

Key Features & Technical Specifications of the Ospura ULP-4040 Membrane:
- Energy-Saving Ultra Low Pressure (ULP): Operates efficiently at reduced feed pressure (tested at 150 psi / 2,000 ppm NaCl), significantly cutting electrical energy consumption for high-pressure booster pumps.
- High NaCl Salt Rejection (99.0%): Produces top-quality demineralized water (permeate) to prevent spot formation and white film deposits on washed vehicles.
- 2,500 GPD Permeate Capacity: Yields up to 9.5 m3 of purified water per day, maintaining an optimal reserve of spot-free rinse water in storage tanks.
- 28 mil (0.7 mm) Feed Spacer: Enhances feed channel hydraulics, ensuring uniform cross-flow distribution and high resistance to particulate fouling.
- Broad pH & Temperature Limits: Operates continuously across a pH range of 3–11 (chemical cleaning range pH 1.5–12) and temperatures up to 45°C (113°F). Maximum operating pressure is rated up to 600 psi (41 bar).
- System Reliability & Cold Weather Care: Pure spot-free water delivery is crucial during winter operation. Learn how to protect water treatment modules from freezing in our winter car wash preparation guide and read more maintenance insights in our article on car wash maintenance tips.
Applications in Water Treatment & Car Wash Automation:
- Reverse osmosis (RO) systems supplying spot-free rinse water for touchless and rollover car wash facilities.
- Industrial demineralization plants treating municipal or tap water with low-to-medium salinity (brackish water).

Frequently Asked Questions (FAQ)
What are the physical dimensions of the Ospura ULP-4040 membrane?
The membrane features standard industrial 4040 dimensions: overall length (A) is 40.0 inches (1,016 mm), outer diameter (D) is 3.9 inches (99 mm), and the end stem connector diameter (C) is 0.75 inches (19 mm).
What is the permeate production capacity and salt rejection rate?
The Ospura ULP-4040 produces up to 2,500 GPD (approx. 9.5 m3/day) of permeate water with a nominal NaCl salt rejection rating of 99.0%.
How does the ULP-4040 differ from the BW-4040 membrane model?
The ULP-4040 is engineered for ultra-low pressure applications (tested at 150 psi), whereas the BW-4040 operates at a higher pressure (tested at 225 psi). The ULP model helps reduce energy consumption while delivering 2,500 GPD output.
What precautions should be taken during initial system start-up?
Prevent hydraulic shocks or sudden pressure surges during start-up. Permeate water collected during the first hour of operation should be discarded. For extended shutdowns, elements should be immersed in a preservative solution to prevent biological growth.
What is the maximum chlorine tolerance for this RO element?
Free chlorine concentration in the feed water must be maintained below 0.1 ppm (<0.1 mg/L). Raw feed water must undergo proper pretreatment (such as activated carbon filtration) prior to entering the membrane.
