[사우디] MBR 기술로 사우디 아람코의 물 회수율 99%로 높여

룹알할리 사막(Empty Quarter)의 샤이바(Shaybah) 유전지대에서 사우디 아람코(Saudi Aramco)의 폐수처리장(WWTP, wastewater treatment plant)기술로의 업그레이드가 완료되었다.

ACWA Emirates가 제공하는 MBR(Membrane bioreactor) 기술을 이용하여 새로운 750m3 / day WWTP 프로젝트가 1997년 제작된 최초의 공장을 대체할 것이다.
 
불리한 Empty Quarter의 사막 환경에서 이 공장은 Aramco의 엄격한 환경 품질 기준에 따라 고품질의 관계용 유출수로 99%의 물 회수율을 제공하고 있다.

ACWA는 계약에 따라 폐수 처리장의 설계, 엔지니어링, 설치 및 커미셔닝을 담당해왔다. 또한 6개월 간의 운영 및 유지 보수 패키지가 포함되어있다.

이 20개월짜리 프로젝트는 2016년 12월에 양도되었다.

MEMBRANE BIOREACTOR (MBR) TECH HELPS SAUDI ARAMCO HIT 99% RECOVERY RATE

An upgrade to oil giant Saudi Aramco's wastewater treatment plant (WWTP) technology at the Shaybah oil field in the Empty Quarter has been completed.

Using Membrane bioreactor (MBR) technology provided by ACWA Emirates, the new 750 m3/day WWTP project replaces an original plant built by the company in 1997.
 
Facing remote and challenging desert conditions of the Empty Quarter, the plant is said to be delivering 99% water recovery with high quality effluent for use in irrigation, in line with Aramco’s strict environmental quality standards.

Under the contract ACWA has been responsible for all aspects of design, engineering, installation and commissioning for the wastewater plant.

This included a six month operation and maintenance package to provide assistance and training.

The 20 month project was handed over in December 2016.

Key components of the supplied plant include inlet pre-treatment headworks incorporating screens, grit and FOG removal, evaporation ponds with feed and return pump chambers, anoxic tanks, aeration tanks, plus the Membrane Bio-reactor tank with air blowers, self-cleaning jet filters and all controls and instrumentation.

ACWA said it re-used plant elements where possible. Examples include an existing aeration tank has been upgraded and modified to serve as a balance tank and the existing sludge drying beds have also been retained.

 
Elsewhere in the region, the company provided the 76,000 m3/day Al Ansab MBR plant in Oman.
