Ultra-Low Pressure RO Membrane Elements
JOZZON’s JEC series ultra-low pressure RO membrane elements utilize an innovative hydrophilic modified membrane process to achieve exceptionally high permeate flow at minimal operating pressures. By maintaining a high 95% salt rejection rate at pressures as low as 36 psi (0.25 MPa), these elements drastically reduce system energy consumption, lower operating expenses, and deliver reliable purified water for residential, commercial, and off-grid applications.
Product Overview
Engineered for energy efficiency and low-pressure versatility, JOZZON JEC series ultra-low pressure RO membrane elements represent a breakthrough in reverse osmosis filtration technology. Traditional home and light commercial RO systems often require booster pumps or higher feed pressures to maintain efficient water production. By optimizing the surface chemistry through hydrophilic modification, JOZZON’s JEC series lowers the required driving force, enabling high water yield under gravity-fed or low-pressure line conditions.
Whether deployed in standard under-sink residential purifiers, off-grid disaster relief units, or rural decentralized water supply systems, these ultra-low pressure elements provide continuous, reliable purification without heavy electricity demand.
Features & Benefit
1. Industry-Leading Low Pressure Operation (36 psi)
Operating efficiently at feed pressures as low as 36 psi (0.25 MPa), JOZZON ultra-low pressure RO membrane elements allow systems to function without energetic booster pumps, making them ideal for low-pressure municipal supplies, mobile water units, and remote locations.
2. Maximum Energy Savings & Reduced Operating Costs
By drastically reducing the required operating head pressure, JEC membrane elements significantly lower pump workload and electrical consumption—delivering the lowest total cost of ownership (TCO) across the system’s operational lifespan.
3. Hydrophilic Modified Membrane Process for Enhanced Flux
Our proprietary surface modification technology creates a highly hydrophilic active layer. This design increases pure water flux and maintains elevated permeate production rates even during low-temperature seasons or under lower feed water temperatures.
4. Reliable Desalination Performance
Despite operating at ultra-low pressures, the JEC series delivers a stable 95% salt rejection rate, effectively filtering out total dissolved solids (TDS), heavy metals, residual chemicals, and trace organic contaminants to ensure clean, safe drinking water.
5. Flexible System Scalability under Variable Pressures
As feed water pressure increases above the baseline 36 psi, both the permeate flow rate and overall salt rejection rate further improve. This flexibility allows system integrators to configure versatile equipment for both home drinking units and light commercial platforms.
