How RO Membrane is made？

Reverse osmosis is the finest level of filtration available. If we want to know How the RO Membrane is made, first we need to know the structure of the reverse osmosis membrane. The structure of a RO membrane element is shown in the figure below, we can see that the core of the RO membrane element is the RO membrane.

The RO membrane acts as a barrier to all dissolved salts and inorganic molecules, as well as organic molecules with a molecular weight greater than approximately 100. Water molecules, on the other hand, pass freely through the membrane creating a purified product stream. Rejection of dissolved salts is typically 95% to greater than 98%. The applications for RO are numerous and varied and include desalination of seawater or brackish water for drinking purposes, wastewater recovery, food and beverage processing, biomedical separations, purification of home drinking water and industrial process water.

HID has now invested in three fully automated reverse osmosis flat sheet production lines. These are exactly the core that HID can produce high-quality RO membranes. The total daily output of the HID RO flat sheet is 20,000 square meters, which can be used not only for HID RO membranes but also for customers worldwide.

Main Features:

★ HID high rejection;

★ Long service life for reducing the cost;

★ High stabilized rejection with realized nominal flux;

★ Sanitary qualified elements;

★ Stringent in-house inspection & testing control.

When you have the core RO membrane of the membrane element, it is not enough to make the RO membrane element. The next article takes you to know what is needed for a reverse osmosis membrane production line.
