콜롬비아 상·하수당국 구역(DC Water)과 햄턴 로드 위생시설 구역(HRSD)이 세계시장에 AVN™ 기술의 특허를 출원하기 위해 공식적으로 World Water Works(WWW)사를 하수처리 솔루션의 설계 및 제조업체로 선정했다.

이 기술은 박테리아 밀도의 구분을 위해 선택압(selective pressure)을 적용하는 동시에 등록상표가 붙은 컨트롤 전략을 활용한다. 이를 통해 하수처리 시스템은 더 효율적인 총질소 제거를 할 수 있게 된다.

 

 

 

The District of Columbia Water and Sewer Authority (DC Water) and the Hampton Roads Sanitation District (HRSD) have officially selected World Water Works, Inc., a designer and manufacturer of wastewater treatment solutions, to bring its patent-pending AVN™ technology to the global market.

 

The technology, which is named for the balance it achieves in ammonia oxidizing bacteria versus nitrite oxidizing bacteria, utilizes a proprietary control strategy, applying selective pressure to aid in the segregation of the desired bacterial populations. This allows wastewater treatment systems to achieve more efficient removal of total nitrogen.

 

AVN will deliver a rapid return on investment to customers by managing the influent carbon, minimizing the alkalinity demands and reducing the energy requirement of the system, while at the same time maintaining superior effluent quality. AVN is literally the ACE™ (alkalinity, carbon, energy) solution for cost-effectively removing ammonia in the mainstream treatment activated sludge process.

 

World Water Works was selected through a public bidding process due to its track record of success in bringing new technologies to market, extensive ammonia removal experience, complementary technologies, and its strong reputation for customer satisfaction. The company was also recently selected to provide its DEMON® wastewater deammonification system to DC Water's Blue Plains Advanced Wastewater Treatment Plant (see "DC Water to house world's largest deammonification system for advanced nitrogen removal").
