스웨덴의 Stockholm Vatten사가 세계에서 가장 큰 MBR 플랜트를 만들고자 현재 기술을 업그레이드하는 계획의 한 부분으로 Henriksdal 지자체 폐수처리 플랜트에 GE사의 새 멤브레인 바이오액터(MBR) 장비를 탑재할 준비를 마쳤다.

스톡홀름 지자체 폐수량의 ⅔를 담당하는 Henriksdal WWTP는 암벽 내에 위치해 있다. 암벽 구조물 안으로 18㎞ 이상을 파고 들어간 터널은 시설을 확장하는 것이 엄청난 도전이다.

 

 

 

Stockholm Vatten, the primary water company for the city of Stockholm, Sweden, is set to receive new membrane bioreactor (MBR) equipment from GE (NYSE: GE) for the Henriksdal municipal wastewater treatment plant (WWTP) as part of an upgrade to its existing technology, making it the largest MBR plant in the world.

 

The Henriksdal WWTP, responsible for treating two thirds of the municipal wastewater for Stockholm, is located inside rock. With over 18 kilometers of tunnels blasted into the rock structure, this presents a huge challenge to expand the utility in the same relative footprint. These drivers steered Stockholm Vatten to select GE's LEAPmbr technology as the right solution for the retrofit and upgrade.

 

The city of Stockholm has one of the fastest growing populations in Europe, and Stockholm Vatten was tasked with both expanding the capacity of the facility and producing effluent of higher quality to meet the country's environmental commitments under the Baltic Sea Action Plan (BSAP) and the E.U. Water Directive.

 

At the core of LEAPmbr is GE's ZeeWeed 500 membrane, an advanced ultrafiltration technology that separates solids, bacteria and viruses from water or wastewater. More than 1,000 plants worldwide use this technology to produce superior quality water. GE's ZeeWeed ultrafiltration membranes offer a combination of performance, energy-efficiency, durability, ease of operation, and reliability.

 

As part of the contract, GE will be delivering a scope that encompasses the design, supply and servicing of the entire membrane filtration package. The contract will be completed in multiple stages and delivered over a period of four to five years. Design will be completed in 2015, and first shipments will begin in 2016. Once the upgrade is complete, it will process up to 864 million liters of wastewater per day.
