Why Reverse Osmosis Membranes Matter
A reverse osmosis RO membrane is the central component of any reverse osmosis water purification system. It works as a selective barrier, allowing only pure water molecules to pass through while rejecting contaminants such as dissolved salts, chlorine, heavy metals, bacteria, and other particles. The result is pure, clean water ideal for drinking, cooking, and industrial applications.
Whether you’re managing a household water filter or operating a commercial purification plant, the right RO membrane determines not only the water quality but also the overall system efficiency and lifespan. That’s why Supreme Water Sales offers top-quality RO membranes that meet exacting industry standards for performance and durability.
Trusted Watts Membrane Technology
Supreme Water Sales proudly offers a range of membrane for reverse osmosis systems from Watts Water Technologies — one of the most trusted names in the water treatment industry. These membranes are engineered using advanced Thin Film Composite (TFC) technology and polyamide materials for excellent salt rejection and long-lasting performance.
Watts commercial and residential RO membranes are specifically designed to handle tap water applications with high rejection rates and efficient flow performance. From compact home systems to large-scale industrial setups, these membranes provide consistent results even under variable temperature and pressure conditions.
Our Product Range
At Supreme Water Sales, we stock a complete lineup of Watts RO membranes to suit a wide range of applications:
Every membrane is crafted with precision and built to deliver consistent, reliable results, ensuring pure water output and minimal maintenance.
Efficiency and Quality You Can Depend On
Each reverse osmosis membrane replacement we offer is carefully designed to provide superior salt rejection (up to 99.5%) while maintaining strong flow rates. These membranes are spiral-wound and negatively charged to optimize contaminant removal and reduce fouling, helping your system operate efficiently for longer periods.
Watts membranes are tested under ideal conditions — typically at 225 psi and 77°F — ensuring the data you see reflects real-world performance. They can withstand up to 400 psi, work across a broad pH range (2–11), and handle varying water conditions without losing effectiveness.
Residential and Commercial Applications
Whether you need a reverse osmosis system membrane for home drinking water systems or for commercial operations like food production, car washes, or laboratories, Supreme Water Sales has the perfect fit.
Our residential membranes, such as the Watts W-1812-100, are designed to fit standard 2” x 12” housings and can easily be integrated into most home RO systems. For businesses, larger units like the W-4040-TW and W-4040-LE are optimized for high-volume performance, ensuring dependable output while maintaining energy efficiency.
Maintaining System Performance
To keep your RO system operating efficiently, timely reverse osmosis membrane filter replacement is essential. Over time, even the highest-quality membranes accumulate scale and sediment, which can affect performance. By replacing your RO membrane regularly, you not only maintain water quality but also extend the life of your overall filtration system.
Supreme Water Sales provides genuine Watts replacement membranes, ensuring compatibility and reliability. Each membrane is packaged in protective preservatives and should be stored in a cool environment for maximum shelf life before installation.
Advanced Membrane Filtration Technology
The reverse osmosis membrane filtration process uses a sophisticated, multi-layered structure that provides exceptional contaminant removal capabilities. The TFC polyamide construction ensures resistance against chlorine degradation, while the spiral-wound configuration enhances flow and minimizes pressure drops.
This advanced design helps achieve a balance between high permeate flow rates and outstanding rejection levels — a must-have for those seeking consistent, high-quality purified water.
Designed for Tap Water Applications
Each reverse osmosis water filter membrane from Watts is tailored for tap water purification, engineered to handle typical municipal water sources. Their robust construction ensures they perform efficiently even when pressure, temperature, or water chemistry varies slightly.
With proper maintenance, Watts membranes deliver stable operation and long service life, providing both peace of mind and excellent value.

Frequently Asked Questions
1. What is a reverse osmosis membrane?
A reverse osmosis membrane is a semi-permeable filter that removes impurities, salts, and contaminants from water, allowing only clean water to pass through.
2. How do I know when to replace my RO membrane?
Most membranes last 2–3 years. Signs of replacement include reduced water flow, a drop in water quality, or unusual taste and odor.
3. Can I use a residential RO membrane in a commercial system?
No. Residential membranes are designed for low-volume use. Commercial systems require larger-capacity membranes for high water output.
4. What water contaminants do RO membranes remove?
RO membranes effectively remove dissolved salts, heavy metals, chlorine, bacteria, and other impurities, providing safe and clean water.
5. How do I maintain a reverse osmosis membrane?
Regularly check water pressure, pre-filters, and flush the system if needed. Timely replacement of pre-filters helps prolong membrane life.
6. Are Watts membranes compatible with all RO systems?
Watts membranes are designed to fit standard residential and commercial RO housings. Always check size and specifications before purchase.
7. What is the difference between standard and low-energy RO membranes?
Low-energy membranes, like Watts W-4040-LE, require less pressure to operate efficiently, reducing energy consumption while maintaining high water output.
