8-inch Low-pressure Membrane Elements
JOZZON's 8-inch low-pressure membrane elements are designed for large-scale commercial and industrial systems requiring high water output with low operating costs. Featuring a rugged fiberglass wound shell, these elements offer excellent pressure resistance, preventing telescoping and ensuring long-term stability. The low-pressure design reduces energy consumption by 15-30%, while high water flux minimizes the number of elements needed.
Product Overview
JOZZON's 8-inch low-pressure membrane elements boast an effective membrane area of up to 400 square feet, with the same external dimensions as other 8-inch membrane elements. The JRW-8040 membrane element operates at low pressure and delivers high permeate flow, significantly increasing the economic efficiency of system operation. The membrane element increases permeate flow by increasing the effective membrane area, rather than the permeate flow per unit area, thus maintaining a low fouling rate and ensuring the membrane element's lifespan.
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
Over 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.
