Techno-Economic Evaluation Of Conventional And Membrane-Based Pretreatment Before Reverse Osmosis, Shamma Ahmed Rashid Al-Malek Jun 2005

Techno-Economic Evaluation Of Conventional And Membrane-Based Pretreatment Before Reverse Osmosis, Shamma Ahmed Rashid Al-Malek

Theses

In this thesis, a technological and economical comparison was conducted on both conventional and membrane based pre-treatment before reverse osmosis desalination. In order to produce high quality water at the design recovery ratio, reverse osmosis membranes should receive high quality feed water in terms of turbidity, suspended solids, and biological matters. Conventional pre-treatment schemes of media and cartridge filters after coagulation chambers have been used for years. Due to the poor performance and decline in reverse osmosis recovery, membrane based pre-treatment has emerged and has been under research and study in the recent years. Few conventional pre-treatment reverse osmosis plants …
