4-inch Low-pressure High Rejection Membrane Elements
JOZZON's 4-inch low-pressure 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.
Product Overview
JOZZON's 4-inch low-pressure high-rejection membrane elements, achieving 99%-99.5% salt rejection, are engineered for applications where permeate water quality is the highest priority. From laboratory ultrapure water systems to medical facilities and beverage production lines, these elements can be flexibly configured to meet various requirements, including high desalination, stable operation, or compact system design.
All elements 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 maintains consistent rejection performance over time. The high rejection rate significantly extends the regeneration cycles of downstream DI or EDI systems, reducing overall operating costs.
Whether you are designing a hospital central water system, a food and beverage processing unit, or a laboratory RO unit, JOZZON's 4-inch high-rejection low-pressure elements provide the perfect balance of water quality, durability, and energy efficiency.
Features & Benefit
1.High Water Flux
Optimized membrane structure and hydrophilic modification deliver higher flow at same pressure, reducing membrane count and initial investment.
2.Excellent Salt Rejection
99%-99.5% salt rejection effectively removes salts and contaminants, ensuring permeate quality and extending downstream system regeneration cycles.
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.
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.
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.
