摘要 |
The present invention discloses a desalination plant that operates with a sea water or brackish water feed and produces a concentrated and selectively improved salt reject stream and a pure water permeate stream from a first treatment section that is arranged to produce primarily water at high recovery using membrane desalination processes. The reject stream from the first treatment line has a component distribution that is substantially reduced in native di- and polyvalent scaling ions, essentially depleted of sulfate, has substantially higher total dissolved solids than a traditional sea water reverse osmosis reject, yet is suitable for thermal treatment processes. The system may be enhanced by monovalent salt components. The unit may be integrated with a second treatment section, in which the first reject stream is further concentrated, purified, and processed to produce a high purity salt product. |
