Source Water Quality
(e.g. salinity, temperature, pollutants) | Primary concerns stem from the chemical conditioning of the source water and the disposal of process residuals. | Source water quality largely determines the extent of pretreatment needed or membrane desalination. | Energy use for pretreatment of brackish water depends on the quality of source water and type of pretreatment process. | Effective pretreatment can reduce membrane fouling and prevent other process complications, thereby reducing annual operating costs. |
Membrane Fouling
(e.g. scaling and particulate, biological and organic fouling) | | Appropriate pre-treatment can prevent fouling, optimize membrane performance and extend membrane life. | | |
