I. INTRODUCTION 

 
 

The separation of dissolved solids and water using RO membranes is a pressure driven 
temperature dependent process.  The membrane material is designed to be as permeable to water 
as possible while maintaining the ability to reject dissolved solids. 
 
The main system design parameters require the following: 

 

 

Internal flows across the membrane surface must be high enough to prevent settling of fine 
suspended solids on the membrane surface. 

 

 

The concentration of each dissolved ionic species must not exceed the limits of solubility 
anywhere in the system. 

 

 

Pre-treatment must be sufficient to eliminate chemicals that would attack the membrane 
materials.
