엔지니어·제조업체인 Meurer Research사는 Inclined Plate Settler와 Vertical Paddle Wheel Flocculators의 제조 마지막 단계에 있다. 이들은 콜로라도 중심의 새 대도시 하수 북부 처리프랜트(NTP)에 제3 하수처리 시설을 제공할 계획이다.

NTP는 현재 콜로라도 Brighton 지역에 지어지고 있는 향상된 하수처리 시설로, 북부 덴버 대도시의 지역발전을 도울 것이다. 이 시설은 2016년 운영에 들어갈 예정이며, 미국 서부에서 가장 향상된 시설 중 하나가 될 것으로 기대된다.

 

 

 

Meurer Research, Inc. (MRI), an engineering and manufacturing company, is in the final stages of manufacturing its patented Inclined Plate Settlers and Vertical Paddle Wheel Flocculators to provide tertiary wastewater treatment equipment for the new, Colorado-based Metro Wastewater Northern Treatment Plant (NTP).

 

The NTP is an advanced wastewater treatment facility being constructed in Brighton, Colo., to support community growth in the northern Denver metropolitan region. Expected to become operational in 2016, the plant is one of the most advanced in the western United States.

 

MRI's custom installation will provide treatment in the four tertiary basins. Total design capacity is 51.4 million gallons per day (MGD), with delivery expected by year-end. Custom-built to the specifications of site engineering firm CH2M HILL, MRI Inclined Plate Settlers and Flocculators are needed to remove phosphorus and provide high-quality effluent that meets or exceeds the stringent standards needed to protect the South Platte River.

 

Chemical feed in the NTP's tertiary phase will be alum and a polymer, which in conjunction with MRI Flocculators will bring phosphorus out of solution and into floc formulation that settles and can be easily removed. High-capacity Inclined Plate Settlers -- created and patented 20 years ago by MRI -- are in operation in a similar tertiary treatment phase at the Snake River Treatment Plant in Dillon, Colo. At Snake River, MRI is experiencing a 90-percent phosphorus removal through the plate settlers prior to filtration.

 

The first installation of the current design of MRI Inclined Plate Settlers was at the City of Arvada, Colorado, Water Treatment Plant in 2001, which is still in operation today. Inclined Plate Settlers produce better effluent quality and reduce the footprint of a tertiary basin by as much as 80 percent over a conventional basin.
