Low-energy Reverse Osmosis Membrane Elements
The JEC series does not increase flow rate by 'squeezing' the membrane to produce more water. Instead, it achieves low-pressure, high-quality, and stable water production without reducing desalination or increasing fouling, through hydrophilic modification and precise increase of membrane area, helping you save electricity, money, and maintenance.
Features & Benefit
1.Membrane Technology
Completely new process; the desalination layer undergoes hydrophilic modification.
2.Core Advantages
Desalination capacity remains unchanged (this is a prerequisite; no performance is sacrificed for increased water output).
3.Operating Pressure
Low-pressure operation with significantly improved permeability.
4.Water Production Capacity
Water production per unit membrane area is comparable to high-pressure products, but at a lower operating pressure.
5.Membrane Area
The effective membrane area is maximized through fully automated winding.
6.Design Philosophy
Achieving a water production balance point through a dual improvement in "hydrophilicity + area", without resorting to destructive methods to maximize the membrane's own water production.
