| [미국] 계절적인 하수처리 과제를 위해 새로운 기술 도입
Biowater Technology는 전세계적으로 주택, 산업 시설을 위한 진화된 생태 하수처리 설비, 운영을 제공하는 회사이다. 최근 이 Biowater Technology는 미시간 주의 Bloomingdale이라는 마을과 자사의 완전혼합교정막(Compete Mix Fixed Film)을 생태 하수처리를 위해 제공하는 계약을 맺었다.
현재 Bloomingdale의 하수처리 시설은 지역의 학교와 식품 공단의 물 다량 배출로 인해 계절적 수자원 과급이라는 특이한 과제를 마주하고 있다. 또한 현재 오수 처리용 인공 못은 새로운 암모니아 기준을 달성하는 데는 부족할 것으로 예상되고 낮은 온도의 하수 또한 문제 해결에 방해가 될것으로 예상된다.

Wastewater treatment solution helps Michigan WWTP overcome seasonal challenges
OSLO, NORWAY, July 8, 2013 -- Biowater Technology, a provider and manufacture of advanced biological wastewater treatment processes and equipment for global municipal and industrial facilities, has been awarded a contract by the village of Bloomingdale, Mich., to supply its Compete Mix Fixed Film (CMFF®) biological treatment process.
Bloomingdale's existing wastewater treatment plant has unique challenges associated with seasonal fluctuation from regional school and food processor discharges. The existing lagoon could not meet new ammonia limits, and cold wastewater temperature exacerbates the problem.
The municipality selected Biowater's CMFF®, based on the MBBR (Moving Bed Biofilm Reactor) concept in which biofilm are fluidized in the bed and remove organics and nitrify ammonia and TKN. "The best solution to overcome the challenges with seasonal fluctuations and cold temperatures was to design a three-stage aerobic CMFF process followed by gravity clarification," says Laura Marcolini, President Biowater Technology US, LLC.
The cold weather in Bloomingdale has a significant impact on wastewater treatment efficiencies. Removing contaminants like BOD, TSS and other nutrients from wastewater is necessary no matter the weather conditions. Biowater Technology's CMFF® process provides an added benefit in extremely cold weather conditions because of its robust biofilm. This technology was developed in Norway and has significant benefits over traditional wastewater treatment processes like Activated Sludge, MBR, SBR, and Lagoon processes.
"Biowater and their biofilm process were pre-selected to bid on this project during the design phase because of their qualifications, expertise, and solution to the seasonal challenge we faced. The delivery met our expectations with no change orders. Start-up, training and initial system performance has met the demands posed," says Cary Bond, of Fleis & VandenBrink Engineering, Inc., (Project Engineer).
