Cuevas de Almanzora BWRO Desalination Plant
Construction, operation and expansion of the desalination plant of the Cuevas de Almanzora Irrigation Subscriber Community.
The plant had in the beginning a water production capacity for irrigation of 20,000 m3/d, and has been successively expanded with a capacity of 35,000 m3/d.
The plant was built by the private initiative of the Irrigation Community and the water produced is almost exclusively for irrigation of the "Poniente Almeriense" area, having supplied more than 120 Hm3 since its operation in 2003.
The treatment process consists of:
- Harvesting brackish water mainly from 6 wells and is stored in a crude water tank of 1500 m3 capacity.
- Low-pressure pumping
- Pretreatment by pressurized silex filters, with counter-current cleaning system.
- 5 micron microfiltration
- Chemical pre-treatment (antincrustant dosing)
- Dual stage reverse osmosis with turbo charger energy recovery and membrane cleaning system
- Remineralization by blending with raw water
- Pumping of treated water drive
