베올리아가 주도하는 합작투자의 스페인지사가 스페인 남부에 위치한 하루 97.2ML규모의 Campo Dalias RO 담수화 플랜트를 완공했다. 이번 1억4천300만 달러 규모의 플랜트는 유럽에거 가장 큰 규모 중 하나로 30만 명의 인구에게 식수를 제공하고 알메리아 지역의 8천㏊ 토지에 관개용수로 공급될 예정이다.

베올리아가 설계·시공한 이 플랜트는 하루 129.6ML 규모 생산량으로 확장됐으며, 베올리아 스페인지사 및 합작투자 파트너사들은 15년 계약 하에 이번 플랜트 운영을 맡게 된다.

 

 

 

A joint venture led by Veolia Water Technologies' Spanish operation has completed the 97.2 Ml/d Campo Dalias reverse osmosis desalination plant in the south of Spain.

 

The 130 million (US$ 143 million) plant is one of Europe's largest and will supply potable water to some 300,000 people and irrigate 8,000 hectares of land in Almeria in Andalusia. It was designed and built by Veolia Water Technologies' with capacity to be expanded to an output of 129.6 Ml/d. Veolia Water Technologies Spain and its joint venture partners will operate the plant under a 15- year deal.

 

The plant has been promoted by the Spanish Ministry for Agriculture, Food and Environment throughWater Spanish Society ACUAMED. It is expected to allow the natural regeneration of the aquifers and avoid their agricultural overexploitation.

 

"The Campo Dalias desalination plant proves the capacity of the Spanish team to design, construct and operate big projects", said managing director for Veolia Water Technologies in Spain and Portugal, .Jose Angel Legaz, "

 

Raw water is drawn through a 1.6 km submarine intake pipe to pretreatment by 40 double- stage filters before going to a double-pass reverse osmosis train. The first pass comprises six skids equipped with isobaric chambers as an energy recovery system that recovers up to 95% of the brine pressure which is then transferred to the feed to reduce pumping requirements.

 

A second, six-skid reverse osmosis pass reduces the boron concentration to less than 0.5 mg/l to comply with irrigation requirements.

 

The desalinated water is remineralized and disinfected step to ensures the output is suitable for human consumption and irrigation.

 

Brine is discharged backed to the see via a 2 km pipe equipped with diffusors to prevent disturbance to marine fauna and flora.
