Water for irrigation
At the time of its construction Carboneras was the largest sea water desalination plant constructed in Europe and one of the largest in the world.
- Proyect: Carboneras Ocean Water Treatment Plant.
- Entity: ACUSUR.
- Location: Carboneras, Almeria. Spain.
- Capacity: 120,000 m3/day.
- The catchment of sea water (sea water intake), is performed using 2 collectors with diameter of 2 metres and 300 metres long, placed on the sea bed.
- Dosage of sodium hypochlorite for raw water.
- Pumping of raw water through 14 pumps that provide a flow of 965 m3/h each.
- Sand filtration through 14 vulcanised horizontal metal filters of 3,000 mm in diameter and 11,000 mm in length.
- Dispersant / anti-crusting dosage system to avoid possible precipitation of salts in the system.
- Safety filtration systems composed of 14 horizontal cartridge filters. Each one of these has 12 cartridges of 20 absolute microns.
- Metabisulphate dosage to neutralise the oxidation agent injected in the previous phase.
- High pressure pumping and energy recover using 14 turbo-pump groups (12+2 reserve) composed of a pump, motor and Pelton turbine.
- 12 Frames with a production capacity of 10,000 m3/day formed by 140 pressure tubes and each with 7 aromatic polyamide membranes.
- 45% conversion.
- Remineralisation through lime and CO2.
- Treated water tanks of 2,500 m3 and 16,500 m3.
- Dilution of the rejected brine with dilution of 4:1 with sea water to avoid any impact on the Posedonia Ocean.
