Company will continue to run plant under six-month operation and maintenance contract
Parkson commissioned a new 2,000 cu meter per day (approximately 0.5 million gal per day [mgd]) plant. The design-operate-transfer MBR plant, which can handle a maximum flow of up to 2 mgd, is located in Rabigh, Saudi Arabia, and will serve the residents of the large residential community that supports the regional Petro-Rabigh oil refinery.
Parkson provided initial design responsibilities for the project, which includes grit removal and screening, balancing tanks, denitrification, fine-bubble aeration, submerged hollow-fiber MBRs and a permeate wet well. The plant, with complete built-in redundancy, includes extensive process controls and 100% monitoring capabilities. In addition to overseeing the plant installation and start-up, Parkson will operate the facility under a six-month operation and maintenance contract, with the possibility of longer-term operational responsibilities.
The privately operated Rabigh Sewage Treatment Plant will meet Title 22 requirements for unrestricted irrigation. In this region of the world, water scarcity is a harsh reality. Parkson’s design will recycle much of the wastewater effluent: at least 70% of the flow will be used for landscaping irrigation throughout the residential community. Parkson believes that this plant will set the standard for the Middle East’s largest oil company, creating a plant that will serve as a model in the region. “This is the first time that Parkson has extended its wastewater treatment process know-how in the Middle East beyond what we traditionally offer–systems and components. I would expect to see Parkson offer more of these ‘design and operate’ services going forward,” said Roland Mueller, general manager of the Middle East for Parkson.
The Parkson-designed MBR plant will need to remove 96% to 99% of the incoming BOD and be able to operate in an environment which can reach 50°C (122°F). “Parkson’s longstanding experience in wastewater process technologies, coupled with its strong local presence, were the main reasons Aramco decided to go with Parkson. Aramco had to choose among the best firms in the industry and Parkson came out on top in their technical and commercial evaluations,” said Saleh Albusaili, vice president of A.A.Al-Busaili.
