[스페인] Avila시 폐수처리장, GE사의 ZeeWeed MBR 기술 적용

스페인의 Avila시는 기존 폐수처리장치의 처리 물량을 배로 확장하기 위하여 GE사의 ZeeWeed 500D 모델인 UF 기술근거의 MBR 설비를 설치키로 했다. 이 프로젝트는 기존 부지면적을 유지하고 기 설치된 인프라를 재이용하는 공사조건으로 nutrients 물질 제거에 대한 새로운 규정을 준수하기 위한 목적이다. 즉 부지면적 확장없이 기존 인프라 설비를 이용하여 경제적 이득을 얻을 수 있게 됐다.

MBR upgrade to double Spanish city wastewater treatment plant capacity

To help meet new regulations for nutrient removal the city of Ávila in Spain will install GE’s ZeeWeed 500D ultrafiltration membrane bioreactor (MBR) technology.

The city’s original wastewater treatment plant was constructed in 1991 to service 190,000 inhabitants with a 30,000 m3/day average flow.

However, due to new regulations, the discharge area of the Cogotas water reservoir was classified as a “sensitive area,” meaning that the new parameters have been placed on effluent quality and require reductions in nitrogen and phosphorous.

The upgrade of the plant’s wastewater treatment processes with the GE MBR technology features four ZeeWeed 500D trains and 32 cassettes. A fifth train is designed for the future expansion, which will expand the plant’s treatment capacity to 37,000 m3/day.

It is anticipated that the membranes will treat the same amount of water while removing all total suspended solids and complying with all other requirements.

GE’s ZeeWeed technology was selected for the upgrade of this plant by the Spanish Consortium Company as ZeeWeed can achieve the technical specifications required on the public tender by Somacyl. Somacyl was awarded the project by UTE EDAR Avila (a consortium formed by Aqualia and Volconsa).
