Improvement in motor performance during high-pressure pump starting at NDDP, Kalpakkam
The major energy requirement required for a seawater reverse osmosis plant is in the form of electrical energy. The primary energy requirement in the process is the electrical energy fed to high-pressure pumps to pressurise the feed seawater to the membranes. This high-pressure pump, being a high inertia load, requires very high torque at the time of starting. This requirement results in ...

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 ...

How is GWT's Seawater Reverse Osmosis Plant Different from Others?
A seawater reverse osmosis plant by definition utilizes the separation of salts and other mineral molecules from water. Freshwater supplies in some parts of the world are dwindling, hard to come by, or are heavily polluted. These are aspects of the growing epidemic of water scarcity.To reduce the strain on freshwater sources, we have to look elsewhere for water and there are no larger sources ...

Influence of feed quality on seawater reverse osmosis performance
The trouble-free operation of a Reverse Osmosis (RO) plant relies on the quality of the treated feed water, which highlights the need for optimisation of the pre-treatment steps. The quality of raw seawater varies with time in terms of suspended and colloidal load, along with the dissolved salt content. In a conventional pre-treatment scheme, consisting of clarification and particulate and micron ...
