[네덜란드] 대규모의 세라믹 멤브레인 식수 플랜트 입증


네덜란드에서 대규모의 세라믹 멤브레인 식수 플랜트를 입증했다. 네덜란드의 물 회사의 PWN기술은 Andijk III의 식수 플랜트에 이온교환과 세라믹 멤브레인 여과 기술을 사용해서 120,000 m3/day라는 결과를 입증했다. 비용은 6천만 유로로 회사 세라믹 멤브레인 기술을 사용한 최대 설비이다. Andijk III는 회사의 영양류염과 유기 물질을 제거하고 물 표면으로부터 질산염과 황산염을 제거하기 위해 Suspended Ion Exchange (SIX)기술을 사용할 예정이다.

Large scale ceramic membrane drinking water plant demonstrated in the Netherlands
Dutch water company PWN Technologies has demonstrated its 120,000 m3/day Andijk III drinking water plant using suspended ion exchange and ceramic membrane filtration technology.

Costing 60 million euros, this is the largest installation using the company’s ceramic membrane technology, following a trial with utility PUB in Singapore (1,200 m3/day) and a smaller trial currently underway with UK utility South West Water of 140 m3/day (see WWi story).

Andijk III will use the company’s Suspended Ion Exchange (SIX) technology to remove natural and organic materials, as well as sulphates and nitrates from surface water.

The major difference between this ceramic membrane installation and others is the use of PWN Technologies’ CeraMac: using 192 membrane vessels (supplied by Japanese company Metawater) grouped together in a single vessel.

PWN Technologies claim this "block" design enables the operator to literally push it harder and enable an increased backwash of up to 5 bar, to clean the membranes, with a downtime per backwash of only a few seconds.

“This is a major step forward,” said Martien den Blanken, CEO of PWN Water supply company in North Holland. “Andijk III is a new standard in treating difficult surface water.”

Cindy Wallis-Lage, president of global water business at Black & Veatch, called Andijk III an excellent example of "disruptive innovation", adding: “This is what makes a difference. It takes a journey to make innovation move faster: integration and sharing of knowledge as well as collaboration.”
