[네덜란드] IX + 세라믹 멤브레인 수처리 플랜트 공개

이온교환(IX)와 세라믹 멤브레인을 결합한 네덜란드의 수처리 플랜트가 PWN에 의해 5월 12일 처음으로 공개됐다. Andijk III 플랜트는 PWN의 SIX와 UV-과산화수소수 기술과 활성탄 여과를 결합한 CeraMac 세라믹 멤브레인 여과 기술을 기반으로 한다. 플랜트의 하루 수용량은 120,000m³이고 비용은 5~6천만 달러이다.

PWN은 "적은 환경 영향과 에너지 소비 절감으로 더 적은 비용을 사용하면서 더 좋은 수질의 물을 생산한다"고 밝혔다. 또한, "SIX는 물 혼탁도를 줄인다"고 덧붙였다.

A water treatment plant in the Netherlands combining ion-exchange (IX) with ceramic membranes was presented to the water industry for the first time on 12 May 2014 by PWN Technologies of Velserbroek.

The Andijk III plant is based on PWN's SIX (Suspended IX) and CeraMac ceramic membrane filtration technologies in combination with existing UV-peroxide technology and active carbon filtration. It has a capacity of 120,000 m³/d and cost   50-60 million.

PWN says that the plant will produce water of a better quality with lower environmental impact and decreased energy consumption at a lower cost. SIX removes water turbidity (dissolved organic substances, nitrate and sulphate).

Jonathan Clement, CEO of PWN Technologies, thinks Andijk III is the most modern pretreatment installation, integrating completely new technologies: "What we do here is not a little bit different, it is unique in the world. A great achievement for the water industry."

The compact design significantly increases the economic viability of the water treatment process, says PWN. "This is a major step forward", explains Martien den Blanken, CEO of PWN Water Supply Company North Holland. "Andijk III is a new standard in treating difficult surface water."

Florida claims US reuse lead with 2.74 million m³/d

An average of 725 MGD (2.74 million m³/d) of treated wastewater is reused every day in the state of Florida, USA, according to statistics published by the South Florida Water Management District. It claims this leads the nation.

SFWMD and other utilities in the state are recognizing 18-24 May 2014 as Water Reuse Week to promote the benefits of using reclaimed water as part of a continuing effort to protect regional water supplies.

Within the district itself, more than 100 reuse systems use an average of 266 MGD (1 million m³/d) providing water for more than 127,000 residents, 269 parks, 199 golf courses and 74 schools.

"Reusing water is essential throughout the state in protecting Florida's water resources," said SFWMD executive director Blake Guillory, who also is on the board of directors for the national Water Reuse Association. "Reuse technologies are continually improving, and, as a result, we're seeing an increase in customized industrial applications--especially as Florida's economy also continues to improve."
