- Copiapó Desalination Plant
The pre-treatment stage uses ACCIONA Agua's proprietary technology to protect membranes from phenomena such as so-called “red tides” and the proliferation of jellyfish, which are typical in this part of the Pacific.
Seawater is taken from the Pacific Ocean at a depth of 17 m and is then pumped to the desalination plant at 1,300 m from the shore. There, the water undergoes a desalination and purification process, and the brine that results from this process is returned to the ocean using a system of diffusers that prevent concentrations of salt that would be harmful to the marine ecosystem. The plant uses reverse osmosis, a highly flexible technology that makes it possible to treat different types of raw water since it is economically competitive and environmentally friendly.
The desalination project is a key part of the South Australian government’s Water Proofing Adelaide Strategy. It provides Adelaide with half of its annual water usage and is powered by sustainable energy sources.
The Tampa Bay project is but one of ACCIONA Agua’s 70 reference plants in the sector with a total installed capacity of over 1.6 million cubic meters per day.
