Seawater Desalination RO Membrane Elements (JSW) Series
JOZZON JSW Series Seawater RO Membrane Elements are engineered for seawater desalination and high-salinity water treatment, combining high salt rejection, stable water production, and optimized operating performance for demanding industrial applications.
High-Rejection Seawater RO Membranes for Desalination and High-Salinity Water Treatment
JSW series seawater desalination RO membranes utilizes world-leading composite membrane coating technology and an optimized polysulfone support layer structure, significantly enhancing the membrane’s compressive strength and ensuring the density of the desalination layer and the overall lifespan of the membrane.
Seawater reverse osmosis membranes combine high desalination rates with low energy consumption, featuring stable performance and consistent water production. They are primarily used in seawater desalination, wastewater reuse and near-zero discharge treatment of high-salt wastewater, and material concentration.
The series covers multiple membrane configurations for different system capacities and performance requirements, including high-rejection, low-energy, and high-flow options.
Why Choose JOZZON Seawater RO Membrane?
JSW Series membranes are developed for demanding seawater and high-salinity applications, combining high desalination performance with optimized membrane structure, stable operation, and proven project experience.
