Ionex SG는 질산을 획기적으로 제거하는 자사의 IX-N™ 시스템을 수자원관리이사회(SWRCB, State Water Resources Control Board)의 식수부문에 의해 캘리포니아에 수처리 시스템에 조건부로 설치하는 승인을 받았다고 밝혔다. 이번 승인은 IX-N 시스템에 대한 다년간의 테스트를 거쳐 식수에서 질산염을 제거하는 안전하고 효율적인 해결책을 제시하기 위함이다.

 

테스트는 또한 제조된 식수의 0.5% 미만으로 기존 시스템의 2% 범위에서 염수 폐기물의 부피를 감소시키는 것으로 효과를 입증했다.

 

 

 

Ionex SG today announced that its breakthrough nitrate removal system, the IX-N™, was conditionally approved for installation in California by the State Water Resources Control Board (SWRCB), Division of Drinking Water. The decision follows extensive multi-year testing that revealed the IX-N system to be a safe and efficient solution to remove nitrates from drinking water. The tests also proved that the system reduces brine waste volumes from the typical two percent range of traditional systems, to less than 0.5 percent of drinking water produced -- a game-changer for ion exchange. The breakthrough is thanks to a proprietary Selective Regeneration™ method that isolates the nitrates into a vastly smaller volume than what's possible with standard ion exchange regeneration methods, while optimizing safe components for re-use.

 

The combination of the patented regeneration technique and Ionex SG's end-to-end waste management/disposal services delivers a robust nitrate removal system with lifecycle costs that are 10X lower than standard ion exchange treatment systems.

 

Ionex SG's Strong Base Anion Exchange treatment process is already deployed in California for removal of hexavalent chromium (chromium-6), with near-zero waste. The technology is highly regarded for its transformative environmental, efficiency and low-cost advantages. Now, with the Conditional Acceptance decision, any public water authority in California can use the same technology platform for nitrate removal, and achieve similar benefits.

 

Nitrates are commonly found in California drinking water and can be harmful to health. In rural areas, the main source of nitrates is fertilizers. Nitrates are also a byproduct of waste-water treatment plants, dairy farms, and leaky septic tanks.

 

"We're delighted to achieve Conditional Acceptance in California where the bar for drinking water quality is so high," said Ionex SG Founder & Director of Technology, Mike Waite. "When it comes to treatment solutions, we learned that our customers' appetite for innovation is matched by respect for the environment. That said, they have high performance expectations for their systems, and their cost priorities are stringent. The IX-N system addresses these essentials. It is ion exchange completely re-imagined with novel features that equip the technology for 21st century deployment. Along with the equipment innovation, customers can expect a complete treatment solution with vastly lower lifecycle costs than what's possible with traditional ion exchange systems."

 

Since 2011, Ionex SG has conducted three demonstration-scale studies in California to fine-tune its Strong Base Anion Exchange Treatment with Sulfate Return Treatment Process for nitrate-contaminated drinking water. In its May 2015 Conditional Acceptance Challenge Study Report, the company documented that through the optimized design and operation of: a) the ion exchange distributor system, b) a multi-stage multi-column lead-lag process, c) a selective regeneration process, and d) a sulfate return process, it is capable of designing, manufacturing and implementing a full-scale ion exchange treatment system that can produce safe drinking water. The Study Report further showed that the system can reduce the brine waste volumes from the typical 2 percent range of traditional systems, to less than 0.5 percent of drinking water produced.

 

Added Waite, "We could not have reached this milestone without the extraordinary cooperation of customers, consulting engineers, and valued suppliers, as well as SWRCB professionals. Their support and guidance throughout this process has helped us deliver a truly innovative nitrate treatment system."
