Successful references – Living sustainability

In the middle of a desert landscape in Oman, we have been operating the world's largest commercial reed bed treatment plant for the cleaning of polluted water from oil production since 2008. The plant is significant not only with a gigantic area of 13.5 km² and a remarkable treatment capacity of up to 175,000 m³ of water per day, but also in terms of sustainability. By using natural flow processes, no energy-intensive pumps are required to treat the polluted water throughout the system. Specifically, the water is fed to the plant via a supply pipeline and passed through an oil and water separator. The water is then distributed by gravity into 4 terraces. Once the cleaning process is complete, the treated water is reused for specific algae growth, agriculture and potable water production.
