아시아의 물 허브도시 싱가포르는 일본의 리드 하에 식수생산을 위한 세라믹 멤브레인을 적용할 준비를 마쳤다. 멤브레인의 신뢰도를 시험하기 위한 18개월의 시범기간 후에 국영 수처리기업 PUB는 이 기술을 이용해 Choa Chu Kang Water Works(CCKWW)를 업그레이드할 계획이다.

2018년 하루 18만2천㎥ 규모로 운영에 들어갈 이 프로젝트는 하루 12만㎥를 생산하는 네덜란드의 Andijk III 식수 플랜트보다 더 큰 규모를 자랑한다. 네덜란드 PWN 테크놀로지(PWN Technologies)는 자사의 ‘CeraMac’ 기술에 일본 Metawater의 멤브레인을 공급할 예정이며, 싱가포르 UGL은 플랜트 설계 및 시공을 맡을 계획이다.

 

 

 

Asia’s water hub Singapore is set to follow Japan’s lead and adopt ceramic membranes to produce drinking water.

 

Following an 18-month trial to determine the reliability of the membranes, national water agency PUB will upgrade its Choa Chu Kang Water Works (CCKWW) using the technology.

 

Set to be operational by 2018 with a capacity of 182,000 m3/day, the project will be larger than the Andijk III drinking water plant in the Netherlands at 120,000 m3/day.

 

Dutch company PWN Technologies will supply its CeraMac® technology with membranes from Japanese company, Metawater. UGL (Singapore) Pte will design and build the plant.

 

Once complete, the CCKWW project will be one of the largest ceramic membrane plants for drinking water treatment in the world.

 

Although novel in Singapore, in Japan there are more than 117 plants using ceramic membranes, with the first installed in 1998.

 

Elsewhere, the uptake in ceramic membranes for municipal drinking water applications has been slower, providing 2-3% market share.

 

With a higher CAPEX, they have proven more popular for industrial applications where the robust properties are required to deal with more challenging waters.

 

Metawater believes ceramics have the advantage if you look at the lifecycle cost, reporting elements that are still operating unbroken for 17 years.

 

Harry Seah, chief technology officer of PUB, said: “We have been studying and testing the merits of ceramic membrane technology for a few years now, and we are satisfied with the results. Both polymeric and ceramic membranes can now be considered in our other waterworks when they are due for upgrading.”
