첨단임상시험의 초기 결과는 에너지 사용과 담수화 및 재이용 기술을 가져오도록 설계되었다. 베이올라(Veolia)는 담수화 전문 기업 SIDEM을 통한 아랍에미리트(UAE) Masdar 신재생에너지 물 담수화 프로그램과 협력을 진행하는 중이다. Ghantoot 지역에 설계된 시험공장은 8월 이후부터 식수를 생산하는 중이다. 이는 대규모 플랜트의 동일한 동작 제약을 준수하며 매우 거대한 규모의 해수를 처리한다.

 

 

Early results have been released from advanced trials designed to bring down energy usage and couple desalination and renewable technologies.

 

Veolia, through its desalination specialist SIDEM, has been collaborating on Masdar’s Renewable Energy Water Desalination Program in the United Arab Emirates.

 

The pilot plant, built in the Ghantoot area, has been producing potable water since August, abiding by the same operation constraints as a large plant and capable of handling very harsh seawater conditions (salinity up to 52 g/l, temperature which may exceed 42°C and harmful algal blooms).

 

Veolia said the trial has demonstrated electrical consumption performances by 7% compared to the contractual target initially required by Masdar.

 

These energy cost savings can be added to those generated by a new pre-treatment design which can save 25% on civil works and, therefore, reduce the footprint of the plant as well as its CAPEX, the company said.

 

Technologies used in the trial include high performance seawater pre-treatment, combining air floatation and filtration, as well as a new osmosis membrane feed configuration able to deal with high treatment fluxes. A Swiss company which Veolia has been partnering with has also been developing new Energy Recovery Devices (ERD) which are implemented on the pilot.

 

In a press release, Veolia said: “Although these are all new technologies, their development is advanced enough to consider them ready for large-scale implementation. The upcoming optimisation phase will allow Veolia experts to push the limits of their system in order to further enhance the design and processes, in the pursuit of even better power efficiency while extending the lifetime of the plant.”
