Leading technology to bring drinking water to millions

2013-07-15 - A reverse osmosis technology solution for the world's largest seawater desalination plant in Algeria will boost energy efficiency and cut maintenance downtime from weeks to days.
The solution is a complete and highly optimized electrical package that will power the Magtaa desalination plant in Algeria at an unprecedented level of

energy efficiency and significantly reduce the length of scheduled plant shutdowns for maintenance.

Located at Oran, Algeria’s second largest city, the reverse osmosis seawater desalination plant will produce up to 500,000 cubic meters of drinking water a
day, enough to meet the daily requirements of about five million people.

ABB has completed the erection, testing of switchgear and equipment supplied. Now, the testing of electric drives and hot-commissioning of the system is in
progress. When operational, in the second half of 2013, Magtaa will be the largest seawater desalination plant in the world using reverse osmosis technology – built,
owned and operated for a period of 25 years by Asia’s leading technology-driven environmental company, Hyflux.

Electrical power consumption is one of the biggest single running costs of desalination, so making the process more energy-efficient directly translates into
affordable potable water.

We are supplying a complete electrical solution for the entire desalination plant and a 220 kV outdoor substation,which will connect the facility to the Algerian power
grid and ensure that the plant receives a reliable supply of electricity without impacting grid stability.

The solution includes 33 medium-voltage drives that will reduce plant electrical losses from the benchmark target of 5 percent to only 3 percent – a huge improvement in energy efficiency, compared to accepted industry standards.

In addition, the drives will speed up the long plant startup process after maintenance or power-failure related shutdowns, reducing the length of plant downtime, compared with the more traditional method of mechanical control.

Over the course of Hyflux’s 25-year operation of the plant, these improvements in energy efficiency, plant productivity and reduced wear and tear made possible by
the ABB solution will provide a huge and sustained boost to plant profitability. As one of the leading suppliers of power and automation solutions to the water
sector, we offer complete capability in integrated and optimized instrumentation, control and electrical (ICE) systems as well as a range of automation products that
improve the energy efficiency, productivity and reliability of plant assets.
