Time to upgrade Carlsbad SWRO design to NF-SWRO Hybrid ?
Dr Ata M Hassan, Blue Revolution Foundation, USA
The author puts forward a novel proposal that San Diego County would get a better deal from Carlsbad with the upgraded performance of a nanofiltration-SWRO hybrid with the reject treated using multi-effect distillation (MED). This RO/MED hybrid idea is under development by several groups, including Saline Water Conversion Corporation, Leading Edge Technologies, Sasakura and Water Reuse Promotion Center. The merits of the idea for Carlsbad or Huntington Beach would require evaluation of availability of steam for the MED process.
