On 5 Jan 2023, global water treatment solutions provider De Nora joined phase four of the Tubli Sewage Treatment Plant expansion. Planning for one of the largest public sector ozone plants to be built in the Middle East since the last decade, the plant expansion was launched in response to rapid population growth in the area. The project will include three dedicated lines of capital controls ozone generators to accommodate an increased flow of wastewater, taking the average daily flow capacity of 200,000m3/day to reach a full average daily flow capacity of 400,000m3/day – a 100% increase.

“Tubli Sewage Treatment Plant phase four will be the one of the largest wastewater treatment plants in the Kingdom of Bahrain,” said Giordano Buizza, De Nora water technologies southwest Europe regional sales director.

Capital controls ozone generators are a preferred treatment in wastewater reuse as they are powerful oxidants with a fast reaction time. The system in Tubli will generate 150kg of ozone per hour to destroy and oxidise residual organic contaminants in wastewater streams to render them harmless. The high-quality effluent will then be reused for irrigation and agricultural beautification purposes throughout the Bahrain service area.

Buizza added, “A universal concern is operating expenses, and that is where our ozone technology offers the greatest benefit. Once the project is complete, we will continue working very closely with our business partner, WTE Wassertechnik over the course of the next decade to keep operating expenses low while continuing to meet environmental goals.”

The ozone installation is part of a larger project led by WTE Wassertechnik, a supplier of municipal and industrial water management serving more than 20 million people in 18 countries.
