Parkson has just commissioned a new 2,000 m3/day (approximately 0.5
million gallons per day) plant. The Design-Operate-Transfer MBR plant,
which can handle a maximum flow of up to 2MGD, 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. With the
Rabigh Sewage Treatment Plant, Parkson has demonstrated its ability to
design an entire treatment plant and assimilate a full suite of
processes and technologies that extend well beyond its own traditional
offerings.
The privately-operated Rabigh STP 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 Middle Eastern oil companies,
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 knowhow 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," says Roland Mueller, General Manager of Middle East for Parkson.
The Parkson-designed MBR plant will need to remove 96-99% of the
incoming BOD and be able to operate in an environment which can reach
50° C (122° F). "Parkson's long standing experience in wastewater
process technologies coupled with its strong local presence were the
main reasons the Petro-Rabigh plant decided to go with Parkson.
Petro-Rabigh had to choose among the best firms in the industry and
Parkson came out on top in their technical and commercial evaluations," says Saleh Albusaili, Vice President of A.A.Al-Busaili.
