남아프리카의 동부 란트 수처리협회(East Rand Water Care Association, ERWAT)가 Royal HaskoningDHV의 폐수처리 기술인 Nereda를 동부 란트 지역에 위치한 Hartebeestfontein 폐수처리 시설에 적용하기 위한 요하네스버그 기반의 WEC 프로젝트 입찰서를 발행했다.

The East Rand Water Care Association (ERWAT) of South Africa has issued a tender to Johannesburg-based WEC Projects, an engineering, procurement and construction contractor, to implement Royal HaskoningDHV's wastewater treatment technology Nereda® at the Hartebeestfontein Wastewater Treatment Works, located near the East Rand region.

 

Royal HaskoningDHV, an international engineering and project management consultancy, is providing the Nereda system -- a new aerobic granular sludge technology that purifies wastewater by controlling the growth and formation of microorganisms -- to improve the capacity of the Hartebeestfontein facility by 5 ml/day.

 

Nereda was invented by the Delft University of Technology in the Netherlands and developed in a unique public-private partnership between the University, the Dutch Foundation for Applied Water Research (STOWA), the Dutch Water Boards, and Royal HaskoningDHV.

 

"The technology represents the next level in the evolution of water treatment technology," said Nereda Global Director, Rene Noppeney. "Aerobic granule treatment is the next technology and is here to stay. The great benefit of Nereda is that it is proven in practice, also in South Africa. It requires less spaces and resources, uses much less energy and involved no chemicals."

 

Graham Hartlett, WEC Projects sales and marketing manager, added, "When this project came out on tender, we immediately recognized that it would be an excellent match for the Nereda technology. The advantages of being able to use the existing infrastructure added much value to the client. Nereda technology can be deployed on a smaller footprint. Capital and operational costs are also big factors to consider."
