자일럼(Xylem)은 기존의 폐수처리플랜트에 고도처리기술을 제공하는 계약을 체결했다고 최근 발표했다. 이번에 계약한 고도처리기술은 체서피크 만(Chesapeake Bay)의 수질을 향상시키는 데 초점을 두고 있는 계획에 핵심 역할을 수행할 것으로 기대된다.

메릴랜드주 프레더릭(Frederick)시는 영양분 초과로 인해 체서피크 만 수질을 저하시킨 도시이다. 이러한 영양분 공급은 조류의 성장을 촉진시키는데, 많은 양의 조류는 해초에 도달하는 햇빛을 차단하고 물에서 산소를 제거하게 된다.

프레더릭시의 공공사업부장 Marc Stachowski는 “체서피크만 지역은 보호되어야 하는 독특한 생태계를 갖고 있다”며 “우리의 목표는 체서피크만 영양분 제거 프로그램 계획의 요구사항을 준수하고, 화학물질에서 UV 살균으로 도시 수처리공정의 핵심 요소를 전환하는 것”이라고 말했다.

 

 

 

Xylem Inc., a company dedicated to solving challenging water issues, recently announced that it has been awarded a contract to provide an existing wastewater treatment plant with advanced treatment technology, which will play a key role in an initiative focused on improving water quality in the Chesapeake Bay.

 

The City of Frederick, Md., is a contributor to the Chesapeake Bay watershed, the water quality of which is being damaged due to excess nutrients entering the system. These nutrients fuel the growth of algae blooms, which in large quantities can block sunlight to underwater grasses and remove oxygen from the water preventing the bay from acting as a healthy ecosystem.

 

"The Chesapeake Bay area is a unique ecosystem that needs to be protected," said Marc Stachowski, deputy director of Public Works for the City of Frederick. "It is our goal to comply with the requirements of the Chesapeake Bay Initiative Enhanced Nutrient Removal program, and as part of this process, the city is converting a key element of its water treatment process from chemical (chlorine) to ultraviolet (UV) disinfection."

 

Stachowski continued, "Xylem is supporting this project by developing innovative and sustainable ways to reduce the levels of nitrate nitrogen and total phosphorus in the water before it is discharged into the Chesapeake Bay." The company will also provide training and service support to the facility's operators as the plant shifts from chlorine to UV disinfection to ensure a smooth and efficient transition.

 

Greg Claffey, Xylem' director of Treatment Sales for North America, said, "By switching from chlorine to UV disinfection, the City of Frederick will reduce the disinfection b-products going back into receiving streams. Furthermore, the removal of chlorine makes the site and the surrounding community a safer place to live and work."

 

Construction is scheduled to take place later this year with the plant scheduled to be in operation in mid-2017.
