Abstract: The seawater reverse osmosis system requires extensive pre-treatment in order to ensure reliable performance. The conventional pre-treatment system involves dosing of chemicals, which requires frequent monitoring of raw water quality, and also involves adjusting the dosage. Besides being cumbersome, there is a lot of time lag involved in carrying out these measures. This calls for pre-treatment systems based on physicochemical mechanisms. During the last few years, Ultrafiltration (UF) has emerged as a leading unit operation in order to render raw seawater compatible with reverse osmosis operations. In this context, the Desalination Division of BARC has already installed an operational UF pre-treatment system. In this paper, we examine the role of UF in the overall operations of the seawater reverse osmosis system.
