The seawater quality and the effluent discharge have
been considered in the design and dimensioning of the
desalination plant, with the aim of complying with the
technical and operational expectations and
requirements. In summary, the design criteria aim to
achieve the following objectives:
• Ensure the guaranteed water capacity, availability
and quality as required, maximizing the availability
of the plant and it components.
• Optimize the energy consumption; in order to
minimize the cost per cubic meter of desalted
water.
• Design the plant in a comprehensive approach
which considers the operation and maintenance
period and the whole life of the project, minimizing
operation and maintenance costs.
• Optimize the quality of the installed equipment
with the best and most reliable suppliers and The scope of the Project includes the engineering, Dissolved Air
