8-inch Low-pressure High Flow Membrane Elements
JOZZON's 8-inch high-flux low-pressure membrane elements deliver an exceptional 12,500 GPD, maximizing water output while minimizing energy consumption. Featuring a rugged fiberglass wound shell, these elements offer superior pressure resistance and long-term reliability.
Product Overview
JOZZON's 8-inch high-flux low-pressure membrane elements, rated at an industry-leading 12,500 GPD, are engineered to meet the growing demand for maximum water production while keeping operating costs low. From large-scale industrial water treatment to municipal drinking water systems and water reuse projects, these elements can be flexibly configured to build systems with various requirements, such as energy savings, maximum water recovery, or minimal footprint.
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 supports stable performance even in multi-element series configurations. The exceptional 12,500 GPD flux means fewer membrane elements are required to achieve target water output, significantly reducing both capital investment and ongoing maintenance costs.
Whether you are designing a large-scale industrial RO plant, a municipal water treatment facility, or a high-recovery water reuse system, JOZZON's 8-inch high-flux low-pressure elements provide the perfect balance of high output, 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
98%-99% 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.
