4-inch Low-pressure High Rejection RO Membrane Elements
JOZZON High Rejection RO Membrane Elements deliver 99%-99.5% salt rejection, ensuring superior permeate quality for demanding commercial applications. Featuring a rugged fiberglass wound shell, these elements offer excellent pressure resistance and long-term stability.
High Rejection Performance for High-Purity Water Applications
JOZZON 4-inch Low-pressure High Rejection RO Membrane Elements are designed for water treatment systems where permeate quality is a primary consideration. With salt rejection of 99β99.5%, the membrane provides effective removal of dissolved salts and contaminants while operating at a relatively low pressure of 150 psi.
The high-rejection membrane is particularly suitable for applications requiring consistently high-quality feed water for downstream purification processes. By reducing the ionic load entering DI or EDI systems, the membrane can help extend regeneration or operating cycles and reduce overall water treatment costs.
Available in the standard 4-inch format, the membrane element combines high rejection performance with a rugged fiberglass-wound shell, optimized membrane structure, and precision manufacturing technology. This makes it suitable for laboratory, medical, beverage, and other commercial water purification systems where stable permeate quality and reliable long-term operation are essential.
Why Choose JOZZON High Rejection RO Membrane
1. 99β99.5% High Salt Rejection
Consistently removes up to 99.5% of dissolved salts, silica, heavy metals, and organic contaminants. This ensures exceptional permeate purity and significantly extends downstream DI resin or EDI module regeneration cycles.
2. Energy-Saving Low-Pressure Operation
Designed with low-pressure drop chemistry and high-hydrophilicity active layers, operational pressure is reduced by 15% to 30% (at 150 psi standard), reducing pump power demands and supporting green production.
3. Rugged Fiberglass Shell Construction
Features a high-strength fiberglass-wound outer shell that resists hydraulic shock and pressure spikes far better than glued alternatives, preventing structural warping and guaranteeing long-term stability.
4. Stable Long-Term Performance
Advanced resistance to chemical degradation and physical compaction slows down flux decline, ensuring steady water output, extended cleaning intervals, and lower replacement costs.
5. Wide Feedwater Compatibility & Anti-Fouling
Incorporates a fouling-resistant, wide feed-channel design that accommodates various feedwater sources (groundwater, tap water, municipal supplies) while reducing pretreatment overhead.
6. Easy System Integration & Replacement
Manufactured according to standard 4040 industrial dimensions, these elements fit seamlessly into mainstream 4-inch membrane housings, enabling fast drop-in replacement, short commissioning time, and simple maintenance.
