CANNON Artes awarded contract for seawater desalination treatment plant
The new facility will treat 34,000m3 of high-salinity seawater daily and will produce demineralised water for steam generation, potable water for plant consumption, and service water for various utilities
CANNON Artes has been awarded the contract for the engineering and supply of a large-scale seawater desalination treatment plant for the Hajr Expansion CCGT IPP Project. This 3GW combined- cycle gas fired power plant is located in Saudi Arabia’s Eastern Province.
The desalination plant is part of a US $2.6bn combined cycle power project developed by a joint venture between ACWA Power, the Saudi Electricity Company, and Haji Abdullah Alireza & Co. Orascom Construction and Técnicas Reunidas are the EPC contractors for this project.
The project was recently assigned and is now entering its detailed design phase, and is said to represent a significant technological achievement in industrial water treatment and desalination under extremely challenging conditions.
The new facility will treat 34,000m3 of high-salinity seawater daily. It will produce demineralised water for steam generation, potable water for plant consumption, and service water for various utilities. Designed to ensure optimal performance and long-term reliability, the system exceeds local regulatory requirements. It also reinforces CANNON Artes’ commitment to environmental sustainability and resource efficiency.
The desalination plant integrates CANNON Artes’ most advanced membrane technologies. These include Ultrafiltration (UF) and Reverse Osmosis (RO) systems, each featuring nearly 22,000m2 of active membrane area. Electrodeionisation (EDI) is used for final polishing. In addition, a remineralisation section with calcite filters will restore calcium and alkalinity to improve water stability and reduce corrosivity, the firm said.
“This project highlights CANNON Artes’ ability to manage highly complex and large-scale water treatment challenges, meeting the most demanding efficiency and environmental standards,” said Mauro Monti, Area Manager CANNON Artes. “Our integrated expertise, from process design to full plant delivery, allows us to deliver tailor-made solutions for critical industrial infrastructures worldwide.”
This project further solidifies CANNON Artes’ position as advanced industrial water treatment, serving the power generation, oil & gas, energy downstream, and petrochemical sectors.
