Overview

N-TECH seawater desalination product series utilizes world-leading composite membrane coating technology, an optimized polysulfone support layer structure, significantly enhancing the membrane's pressure resistance.

This ensures the denseness of the desalination layer and extends the lifespan of the membrane. The seawater reverse osmosis membrane combines high desalination rates with low energy consumption, offering stable performance and consistent water production. It is primarily used in seawater desalination, high-concentration salt wastewater reuse, minimum- zero discharge treatment, material concentration, and other applications.

 

SW-HR:

Superior rejection, excellent durability

SW-HRLE:

High rejection, Low energy

SW-XLE:

High flow, eXtra low energy
