The company EMALSA operates the most important desalination station of Agua de Mar (E.D.A.M.) in the Canary Islands with an average daily production exceeding 80,000 m3. The Piedra Santa industrial water production complex is considered a pioneer worldwide due to its continuous implementation of improvements in the design and modes of operation.
The EDAM called “Las Palmas III” has been characterized by implementing technological measures that have taken advantage of the shortage of available space to increase the quality of the water produced and reduce energy consumption. Over the last few years, various systems have been successfully implemented to improve energy efficiency, based on the technology of isobaric chambers in a double-stage reverse osmosis process, patented by EMALSA itself.
The Santa Piedra desalination complex has several production lines since the installation has had several production extensions since its inauguration. Specifically, the present project affects the two lines known as chassis K (10) and L (11) respectively or the “ISOLUX” plant since it was the contractor that executed the project in 2004.
The purpose of this project is to define the following main aspects:
- Description of the main characteristics of the EDAM at present.
- Define, calculate and measure the works needed to improve energy efficiency.
- Evaluate economically the savings expected in the installation
- Calculate the partial and total amount of the works, specifying the different units with their respective unit prices
- Serve as the basis for the realization of the corresponding administrative authorizations.
