4월 파리에서 열리는 Water Technology Idol에 참가하는 특허 출원 중인 담수화 공정은 토양이 용해되는 전체적인 농도(TDS)를 300,000 mgl 에서 150 mg/l. 이하로 줄일 수 있다고 주장했다.

TDS 감소는 이전 처리 기술보다 운용 자금 비용을 효과적으로 감소 할 수 있다. 

이 공정은 또한 재생 회사가 유독성 갱내수를 경제적으로 재생하고 고용해 액상토양을 사용 가능한 깨끗한 물과 고체 쓰레기로 전환하는 광범위한 응용성을 갖는다.

 

A patents-pending chemical desalination process, which will be presented as a Water Technology Idol contestant in Paris in April, claims to reduce concentrations of total dissolved solids (TDS) in excess of 300,000 mgl to less than 150 mg/l. 

Advanced Water Recovery (AWR)'s process uses a recoverable chemical saturation to concentrate and precipitate dissolved salts out of any water stream, at ambient temperature, making all of the water suitable for reuse or surface water discharge. The resulting >80% dry solid waste can be selectively separated for valuable byproducts, or disposed of in an ordinary landfill. 

TDS reduction is accomplished at dramatically reduced operating and capital costs, compared with existing treatment technologies, says AWR. The process has wide-ranging applications, from toxic mine water treatment to economical total water recovery on existing desalination plants, converting high dissolved solids liquids into clean usable water and zero liquid waste. 

The South Dakota-based company is currently constructing a commercial produced water treatment facility in the Marcellus shale region in Pennsylvania, which is expected to be operating in summer of 2014. The company is currently seeking commercialization partners.
