Xylem has won a major contract valued at more than $8 million USD to develop and supply customized technologies to a wastewater treatment and reclamation plant in Sulaibiya, Kuwait. Following a plant expansion currently underway, it will be one of the largest water reclamation facilities of its kind in the world.
Kuwait’s average rainfall is less than 120 millimeters (mm) annually. Groundwater is the main naturally-occurring water resource, providing 36 percent of Kuwait’s annual water supply, including 90 percent of the water used for irrigation and landscaping. However, this precious resource is overexploited, depleting rapidly and subject to pollution from various sources such as oil exploration and refining, insecticides, pesticides and fertilizers used for agriculture, landfill sites, industrial and commercial operations and soil contaminated by hydrocarbons during the 1991 Gulf War.
The expanded facility will serve the growing irrigation needs of the southern and western Kuwait catchment areas, treating 600,000 cubic meters of wastewater per day, using ultra filtration (UF) and reverse osmosis (RO) as tertiary treatment and polishing stages.
“We are delighted to be playing a key role in the expansion of what will be one of the largest water reclamation plants of its kind in the world,” said Vincent Chirouze, regional director for Xylem’s Middle East and Africa region, “In conjunction with Kharafi National, the project contractor, our optimized solution during secondary treatment will help create an efficient and effective system that will deliver clean reusable water to this arid, water-challenged region.”
Xylem will supply highly efficient and reliable treatment technologies for use during secondary treatment at the plant, including the company’s Sanitaire fine bubble aeration technologies, Flygt ultra low-head pumps and low-speed mixers, aeration blowers, stainless steel air mains and Flygt Jet aerators in the aerobic digesters. These technologies will ensure adequate secondary effluent quality for further treatment and polishing during tertiary stage.
Mr. Dimitris Anagnostopoulos, Project Director for Kharafi National, said, “We are looking forward to the implementation of various equipment performance and optimization concepts that Xylem’s engineering and research and development (R&D) teams have developed. Xylem’s willingness and commitment to join hands with Kharafi National and help us to expedite the project execution phase is commendable.”
Xylem previously worked in a similar role with Kharafi National during the first phase of the development of the treatment plant. Expansion of the plant is expected to be completed by autumn 2016 and will be operational from Q1 2017.
