Low Pressure Commercial Reverse Osmosis Membrane Element
Engineered for commercial water purification systems, JOZZON Commercial RO Membranes provide high salt rejection, stable water production, and energy-efficient performance for reliable everyday operation.
High-Flux, Low-Energy Commercial RO Membrane Solutions
JOZZON’s low-pressure commercial membrane elements, including the compact 2521 and standard 2540 models, are engineered to meet the diverse needs of a wide range of users. From small-scale point-of-use systems to larger commercial installations, these elements can be flexibly configured to build systems with various requirements, such as high desalination, energy savings, or maximum water recovery. Both the 2521 and 2540 models feature a rugged fiberglass wound shell, offering better pressure resistance than traditional glued or taped alternatives. This robust construction prevents membrane telescoping under fluctuating operating conditions, delivers a longer service life with fewer failure risks, and supports higher water production by enabling stable operation at optimized pressures. Whether you are designing a vending machine, a light industrial system, or an office RO unit, JOZZON’s 2521 and 2540 low-pressure elements provide the perfect balance of compact footprint, durability, and output efficiency.
Why Choose JOZZON Commercial RO Membrane
Â
1. High Water Flux
Optimized membrane structure and hydrophilic modification deliver higher flow at same pressure, reducing membrane count and initial investment.
Â
2. Excellent Salt Rejection
Over 99% salt rejection effectively removes salts and contaminants, ensuring permeate quality and extending downstream system regeneration cycles.
Â
3. Reduced Energy Consumption
Low-pressure drop design and high-hydrophilicity materials lower operating pressure by 15-30%, cutting electricity costs and enabling green production.
4. Stable Long-Term Performance
Excellent resistance to chemical degradation and compaction ensures slow flux decline, with a 3-5+ year service life and fewer cleaning/replacement needs.
Â
5.Wide Feed Water Compatibility
Fouling-resistant, wide-channel design adapts to various water types (groundwater, reclaimed water, etc.), resisting fouling and reducing pretreatment requirements.
Â
6.Easy System Integration
Standard industrial dimensions compatible with mainstream membrane housings and pipes enable quick drop-in replacement, short commissioning time, and easy maintenance.
