Most of the potable water in the Gulf region is produced through seawater desalination. This process utilises a vast amount of energy and plays a major role in contributing to the region’s carbon footprint. The commissioning of Alba’s seawater desalination plant in 2001 as an integral component of the company’s Calciner plant was a landmark in the company’s history, confirming its pioneering role in sustainable and environmentally sound practices.
The energy we use in the aluminium production process is simultaneously employed in the water desalination process. The desalinated water is used in the cooling process. The steam that results from this process is then used to generate additional power that helps in saving valuable natural gas energy. This results in Alba producing enormous amounts of potable water that is contributed to Bahrain’s Electricity & Water Authority for general consumption in the Kingdom.
No water gets wasted as we utilise the surplus for a variety of uses in and around the plant. One of the prominent uses of this excess water is to irrigate the more than 153,500 square meters Her Royal Highness Princess Sabeeka Oasis where more than 15,000 trees, flowers, vegetables and shrubs can be found along with an artificial lagoon where the remainder of treated water is gathered to attract migratory birds and turtles and assorted creatures. The way we save, produce and recycle water is one of the most powerful examples of Alba’s corporate social responsibility initiatives.
The seawater desalination plant conforms to the World Health Organisation (WHO) and Gulf Standards. It utilises waste heat from the calcining process to generate steam for the production and supply of 41,000 cubic metres per day of potable water to Alba and to the public water distribution networks.
