Key Saudi Contract For ACWA
27 April 2011, News release from ACWA Services
ACWA's extensive experience in providing state-of-the-art membrane treatment systems in the Middle East has enabled the company to win a key contract from Saudi Arabia's Ministry of Finance for a comprehensive wastewater treatment and reuse.
The plant, which will be sited in the western region of the country between the cities of Makkah and Jeddah, will have a 12,000m3/day capacity and will feature ACWA's award-winning Memtreat® membrane bioreactor technology (MBR).
The turnkey contract involves engineering, procurement, delivery, construction, installation and commissioning of the treatment solutions including the required pretreatment.
The treatment process will include all necessary coarse/fine screening, de-gritting and anoxic pretreatment ahead of the Memtreat® bioreactor. The plant will be constructed with four identical 3000m3/day streams, providing the facility with the flexibility during operation to bring in additional treatment capacity as flows increase, and redundancy for maintenance purposes.
The treated effluent is of an extremely high quality, suitable for direct discharge without further treatment for uses such as irrigation, district cooling, batching plants and industrial process waters. In this desert area, the main planned use for the effluent is irrigation.
Downstream of the MBR system, the Al Shumaisi plant will provide final disinfection using chlorine to prevent regrowth of organics during storage. The waste sludge will be dewatered using a belt press.
The plant will have a high degree of automation and therefore the reliability of the technologies used was critical. The contract also calls for an extremely high quality effluent with a BOD and TSS of less than 5ppm. The treated wastewater quality is such that it will be designated for unrestricted use - lower quality wastewaters have strict restrictions on the types of crops to which they can be applied.
The demanding 12-month timescale of the project is a further challenge following an extremely competitive tendering process that pitted ACWA's formidable local experience and reputation against an array of local and international companies.
ACWA Emirates General Manager, Gary Jackson, said: "ACWA is extremely proud to have won this prestigious contract. Our success is due to our considerable reputation for technical expertise and track record in providing reliable, cutting-edge MBR systems across the region, including one of the world's largest at Al Ansab in Oman which treats a flow of 76,000m3/d.
"ACWA has built over 33 MBR plants in the last seven years in this region alone, and we have a reputation for providing high-quality, cost-effective and energy-efficient solutions exactly tailored to our clients' needs."
ACWA is in the process of opening an operational office in Saudi Arabia to serve this key market, offering construction services to clients in addition to its operation and maintenance expertise. The company also has offices in Oman, Dubai, Abu Dhabi, Bahrain and Jordan. Gary Jackson said: "Our extensive presence in the Middle East means that the expertise we bring and the durability and quality of our solutions is well known. We hope to leverage this existing body of work and reputation to expand our services to what is, for us, one of the key regions in which we work."
