최첨단 공기중 용해 정화 기술을 이용해 처리 과정 초반 엄청난 양의 해조를 제거하는 하수 처리 시설이 카이저(Kaiser) 전자 회사에 의해 800만 달러라는 자금, 1년이라는 시간을 통해 스타운튼(Staunton)시에 설치되었다.

이 공기중 용해 정화 시스템은 기존 정화 작업에 사용되었던 비싼 처리 화학물의 사용을 급격히 절감하였다. 이 시설의 약 80%는 지하에 설치되었고 나머지 지상에 위치한 주요시설과 파이프들을 주변 경관과 조화를 이루도록 설계, 완성되었다.

ST. LOUIS, MO, July 1, 2013 -- An $8 million, year-long project to construct a new water treatment plant in Staunton, Ill., that utilizes a state-of-the-art dissolved air flotation (DAF) clarification system to remove a significant amount of algae at the beginning of the treatment process, has been completed by Kaiser Electric.

The DAF system drastically reduces the need for expensive treatment chemicals often used in a traditional sedimentary process.  Approximately 80 percent of the facility is located underground, with major structures and piping out of view and designed to blend in with its surroundings. 

The total project included construction of one building to house the water treatment plant and installation of the Clari-DAF system, three dual media gravity filters, one standby generator, one bridge crane, one buried sand wastewater filter, one chemical feed system, two high service pumps; and installation of pipe for process sewers, storm sewers, chemical feed, process water, potable water, non-potable water and sludge.

Kaiser Electric's crews were charged with installing electrical service for the new plant, plus providing new service to an existing pump station. Additionally, Kaiser installed two standby generators and all of the power, lighting and distributive control system for all pumps, aeration, filters, tanks, valves and chemical feed systems at the new facility.

The general contractor on the Staunton project was Korte & Luitjohan Contractors, Inc. of Highland, IL and the architect/engineer was Heneghan & Associates of Columbia, Ill.
