Water company news (September 2008)

Abstract

Company news S pecialised water treatment company VWS Envig has been awarded a contract to supply a 2 400 km3/day desalination plant to Transnet. The turnkey project involves the design, manufacture, installation and commissioning of a reverse osmosis (RO) desalination plant for use at Transnet’s iron-ore terminal at the Port of Saldanha. The harbour is South Africa’s only iron-ore handling port, and this contract forms part of a larger upgrade and expansion project. Project manager Thys Els says the plant will be able to be upgraded to a capacity of 3 600 m3/day if necessary. The project will be executed in two phases, namely a design phase and supply phase, with the latter depending on approval of the Record of Decision. “The plant will process seawater to potable standards to be used for dust suppression in the iron-ore terminal. The company is using municipal water for this purpose at present,” explains Els. The new plant will comprise a seawater intake, RO units, a clean-in-place system, energy recovery system and a storage tank.
