The application fields of STRO membran

Features of STRO Membrane

1. Improvement in Feed Water Channel

Among the many anti-fouling mechanisms, the width of the feed water channel of reverse osmosis membrane elements is already a recognized most important indicator of the anti-fouling performance of membrane elements, and also a key consideration for users when choosing products. The STRO membrane element is a spiral-wound membrane, but it differs from traditional spiral-wound membranes. The problem with traditional spiral-wound membranes is that their spacers are prone to clogging and scaling, which restricts the feed water channel and increases the pressure difference. To address this issue, the STRO membrane element combines the advantages of open-channel and spiral-wound element designs, creating a membrane element with a narrow but open channel structure. This design greatly optimizes the feed water channel and the effective area of the membrane, significantly alleviating the shortcomings of traditional spiral-wound membranes.

2. Improvement in Winding Method

   
   
   

The STRO membrane has undergone improvements in its winding method: shorter leaves and increased number of leaves. The advantages of this are: shortened length of the freshwater channel, reduced pressure loss in the freshwater channel; ensuring that the net driving pressure along the membrane is approximately the same; maintaining equal water flux across different areas of the membrane surface; and reducing the degree of concentration polarization.
