Assessment of an ultrafiltration pre-treatment system for a seawater reverse osmosis plant
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 ...

A New Fast Acting Low PH Cleaner Paves the Way for a New Cleaning Philosophy for Integrated Membrane Systems
Abstract For many years ultrafiltration/microfiltration (UF/MF) has been replacing multi-media filtration as a seawater reverse osmosis (RO) or nanofiltration (NF) pre-treatment system. Initially the systems were treated as individual unit operations and optimized as such. However, the similarity in the flux maintenance requirements of the particle removal membranes and the desalination ...

Innovative seawater intake for reverse osmosis desalination plants
Seawater desalination plants typically consist of four major unit operations: seawater intake, pretreatment, Reverse Osmosis (RO) stage, and posttreatment and brine discharge. The best way is to go through vertical beach wells, but the increase of the production capacity of the plants built in recent years makes open intake the only solution. These open ocean intakes draw seawater through the ...

Experiences in the construction and operation of a nuclear desalination demonstration plant
A hybrid desalination system of 6300 m³/day capacity has been envisaged, comprising 4500 m³/day Multi-Stage Flash (MSF) and 1800 m³/day Seawater Reverse Osmosis (SWRO) plants, and sharing basic utilities with Madras Atomic Power Station. The SWRO plant has been commissioned and has been operating for more than two years. The MSF plant is under construction. The construction of the MSF plant has ...
