First year performance review of Magong UF/RO Seawater Desalination Plant

Abstract

The aim of this article is to describe the long term performance of one of the first Seawater Reverse Osmosis desalination plants with Ultrafiltration as pre-treatment. The plant in question is located in Magong (Taiwan) and has a current capacity of 5,500 m3/day. In the near future this current capacity will be increased up to 13,000 m3/day. The Magong desalination plant is an important example of how Ultrafiltration is a key component in seawater desalination plants to ensure sustainable and reliable operation of the downstream reverse osmosis installation. When the Magong desalination plant was initially started-up in 2002 it had a conventional pre-treatment. After six years of less than satisfactory performance, the conventional pre-treatment was replaced by a Ultrafiltration system. Nowadays the plant consists of a self-cleaning Filter, the Ultrafiltration units, Cartridge Filter and Reverse Osmosis lines. The Ultrafiltration system contains 7 racks, each with 60 modules DOW™ Ultrafiltration SFP2860....
