High-Flow 8-inch RO Membranes for Large-Scale Systems
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.
Why Choose JOZZON RO Membrane 8 High Flow
Â
