Case Study: Mitigating Severe Organic Fouling in a Brackish Groundwater Reverse Osmosis System
The Torrance Desalter could not be commissioned after a two year expansion because of increases in interstage feed pressure to the 2nd stage. The initial assumption was that scaling was occurring. However, an autopsy and cleaning study determined that the foulant was entirely organic in nature. The approach was to mitigate the problem by resolving ...
The Perils of Using Chloramines for Pretreatment of Water Reuse RO
The use of chloramines has become a standard pretreatment method for biofouling control in water reuse RO. When used in the 2 - 3 ppm range, chloramines have been known to cause only minimal losses in salt rejection, and the benefits are generally believed to far outweigh the risks. However, in recent years, significant irreversible declines in per...
