Bluewater Bio International has announced that its proprietary HYBACS® US $20 million wastewater treatment plant upgrade at Tubli Water Pollution Control Centre Kingdom of Bahrain, has received flows for the first time.
The introduction of flows to the HYBACS plant was overseen by key personnel from the Sanitary Engineering Planning & Projects Directorate, the project management division for the Ministry of Works. This completes the first stage of commissioning of the largest environmental improvement project of its kind in the region, serving a population equivalent of 800,000. The project is being implemented in two stages to meet the client’s continuous treatment requirements with overall completion due in October 2013.
The 8 million Bahraini Dinar (c US $20 million) landmark project, awarded by the Ministry of Works and executed by BwB, was in response to overloading at the current wastewater treatment works at Tubli WPCC. The original plant was designed for a capacity of 200,000m3/d - however, as a result of rapid urbanisation within the Kingdom, it now receives in excess of 300,000m3/d.
The upgrade of the Tubli plant using HYBACS alleviates the overloading problem without the requirement for green-field construction, using the existing secondary treatment assets whilst avoiding additional land take.
The upgrade comprises the conversion of 2 of the 10 existing aeration lanes and 4 of the 12 existing clarifiers into the HYBACS plant, with 42 SMART™ units (the key component that drives the HYBACS process) positioned upstream of the aeration lanes.
The 100,000m3/d excess flow is diverted after the existing preliminary treatment works to the HYBACS plant, meaning that the HYBACS plant is treating approximately 33% of the full plant load with only 20% of the existing secondary treatment capacity.
Dr. Jeremy Biddle, Technical Director of Bluewater Bio commented:
“The HYBACS plant at Tubli WPCC is the largest of its type in the world. The first half of the HYBACS plant was commissioned at the beginning of June and, like any biological treatment process, it takes time to acclimatise and achieve full capacity. It is now nearing full capacity and performance has been excellent. The concentrations of ammonia and organic material in the treated water comfortably surpass the permitted concentrations for safe discharge into the sea, or for irrigation uses.”
Daniel Ishag, Founder and CEO of Bluewater Bio, a leading provider of innovative high-performance, cost-effective water and wastewater treatment technologies, added that by October this year, the company expects to be unveiling the full operation as a showpiece project to Bahrain, its neighbouring countries, and further afield.
The project falls within the Bahrain Vision 2030, under which improvement of the Kingdom’s infrastructure is a high priority. With the HYBACS upgrade now eliminating immediate concerns at the works, the long term Master Plan for the Tubli Wastewater Treatment Plant improvements can be fully planned, designed and implemented.
