8-inch Low-pressure High Rejection Membrane Elements
JOZZON's 8-inch low-pressure high-rejection membrane elements deliver 99%-99.5% salt rejection for large-scale systems requiring superior water quality. Featuring a rugged fiberglass wound shell, these elements offer excellent pressure resistance and long-term reliability.
Product Overview
JOZZON's 8-inch low-pressure high-rejection membrane elements, achieving 99%-99.5% salt rejection, are engineered for large-scale commercial and industrial applications where permeate water quality is critical. From industrial boiler feedwater treatment to municipal drinking water advanced treatment and pharmaceutical water systems, these elements can be flexibly configured to meet various requirements, including high desalination, stable long-term operation, or maximum water recovery.
All elements feature a rugged fiberglass wound shell, offering better pressure resistance than traditional 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 even in multi-element series configurations. The high rejection rate significantly reduces downstream treatment burden, extending the regeneration cycles of DI or EDI systems and lowering overall operating costs.
Whether you are designing a large-scale industrial water plant, a municipal water treatment facility, or a high-purity water system for power generation, JOZZON's 8-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.
