Ras Al Khaimah Waste Water Authority (RAKWA) has awarded Veolia to upgrade its existing Al Fileyah wastewater treatment plant of the city of Ras Al Khaimah, one of the seven emirates of the United Arab Emirates (UAE).
To double the capacity of the plant, Veolia’s subsidiary and Dutch-based Biothane will deliver four Upthane anaerobic wastewater reactors.
The contract for the upgrade was signed at the Weftec trade fair in New Orleans, USA on 5 October.
The expansion follows a similar project in the next-door emirate of Ajman where Veolia is currently doubling the capacity of a wastewater treatment plant, also involving Upthane anaerobic reactors (on top photo).
Increasing inlet flow
In Ras Al Khaima the inlet flow has increased significant over the years and an issue of odor nuisance has araised, making RAKWA to request Veolia to upgrade the existing plant capabilities.
The project focuses on doubling the capacity of the treatment plant, bringing it from 20.000 to 40.000 cubic meters per day.
In order to achieve this target, the Veolia team will implement the four Upthane anaerobe reactors (50.000 m3/d hydraulic capacity), next to the secondary biological treatment processes, including installation and upgrades of aeration tanks and clarifiers.
The engineering, procurement and construction and commissioning has to be ready in twelve months.

Chief Operating Officer Thierry Froment, at Veolia water technologies in the Middle East, said: “This partnership marks the beginning of a significant journey for us with the Ras Al Khaimah Wastewater Authority and also highlights our commitment to becoming a trusted partner of the UAE, where sustainability is a key priority.”
Chairman Eng. Ahmed Mohammed Al Hammadi, at RAKWA, also commented: “The extension of Al Fileyah treatment plant is very important for RAKWA as it strengthens our strategy to enhance the overall development of Ras Al Kheima Emirates”.
Sewage enters the Upthane reactor through a gravity fed influent distribution system that guarantees maximum contact between the incoming sewage and the anaerobic biomass in the reactor.
Sewage enters at the bottom of the reactor and following an upflow path passes through a thick anaerobic sludge blanket. Here, through the process of anaerobic digestion, wastewater is converted to biogas.
In the upper section a gas-liquids-solids (GLS) separator directs biogas into the gashood from where it can be collected. The biogas contains approximately 75 percent methane and can be utilised to provide the energy needs of the entire WWTP in a combined heat and power unit.
