| [미국] 폐수처리에 하이브리드 중공사막/ 평 막 공용의 MBR 기술사용
미국 캘리포니아 모하베사막 지역의 Victor Valley Wastewater Reclamation Authority (VVWRA) 는 2곳의 MBR 플랜트에 Fibracase 사 제작의 하이브리드 멤브레인 기술을 채택하기로 결정했다.
이곳 MBR 플랜트는 7,570톤/일 규모의 재이용수를 생산하여 조경용수로 사용하고 있으며 이번 설치되는 FibrePlate 브랜드의 하이브리드 멤브레인은 새로 개발된 제품으로 투자비용 및 운전비용을 절감하기 위한 목적으로 중공사막과 평 막의 가장 큰 장점만을 통합하여 제조된 것이다.
한편 취수시스템에 유입되는 부하 량을 절감시켜 수요 증가에 따른 새로운 투자 확장계획을 보류하고 별도의 에너지 사용 절감을 시도하였다.

New hybrid membranes chosen for Victor Valley MBRs
The Victor Valley Wastewater Reclamation Authority (VVWRA), on the edge of the Mojave desert in California, has selected FibrePlate™ hybrid-membrane™ technology manufactured by Fibracast Inc for two sub-regional membrane bioreactor (MBR) facilities.
The MBR facilities will be located in high growth areas of the service region and produce a combined 2 MGD (7,570 m³/d) of high quality effluent for landscape irrigation.
"FibrePlate membranes are a game-changing technology and they are the first 100% newly designed membrane that the industry has seen in a long time," said Andrew Benedek, executive chairman and chief technology officer of Canada's Anaergia, which owns Fibracast.
"The hybrid-membrane™ combines the best advantages of hollow-fibre and flat-sheet technologies to deliver a significant capital and operating cost advantage to our clients."
in 1980, Benedek founded Zenon Environmental, which developed ZeeWeed ultrafiltration membranes and was bought by GE in 2006.
In addition to providing a drought-proof supply of water, the sub-regional MBR facilities will reduce the overall load on the collection system, enabling VVWRA to defer costly infrastructure expansion and reduce the energy costs associated with pumping recycled water.
"This is a critical project that will help to ensure the future sustainability and economic prosperity of our communities," said Logan Olds, general manager of VVWRA. "We have a proven track record of employing best-in-class technologies to help solve critical wastewater infrastructure challenges.
FibrePlate represents a new generation of membrane technology that offers unique operational efficiencies including future capacity expansion capabilities for the VVWRA."
