[싱가포르] Hyflux, 선박이용 부유형 on-board 담수화 플랜트 개발 추진
                                      

싱가포르 Hyflux사는 싱가포르 주최의 SIWW에서 FDPV (floating desalination production vessel)을 선보였다. 이 선박은 긴급하게 깨끗한 물을 필요로 하는 지역사회나 기관업체를 목표로 설계된 것으로 3만톤/일 규모로 선박의 길이는 112m 이다.

Hyflux사의 UF 멤브레인이 미생물 및 박테리아 제거용으로 사용되며 필요한 전기는 선박내 설치된 2기의 제너레이터에서 공급되며 에너지회수장치도 설치예정이다. 또한 2기의 RO 장치로 UF 멤브레인으로부터의 생산수를 처리하여 최종 생산수는 선박내 탱크내에 저장된다. 폐수 배출 기준치의 증가 및 추진상의 환경적 제약등이 강화되므로 이러한 Off-Shore 방식의 해수담수화 처리가 주목을 받고 있다.

이스라엘 IDE사는 일본의 선박제조업체 및 정부와 이러한 처리방식의 추진을 위하여 협의을 진행하고 있으며 노르웨이의 EnviroNor사는 노후화된 oil tanker 선박을 폐선하는대신 floating wastewater treatment vessel로 개조하여 사용하는 개발을 하고 있다. 이러한 모바일 개념의 수처리 시장규모는 2016년에 9억불 매출이 발생할 것으로 Frost & Sullivan은 추정하고 있다.

Floating desalination vessel nearing first commercial roll out

Water company Hyflux used the Singapore International Water Week to showcase a model of its floating desalination production vessel, known as a FDPV.

With a capacity of 30,000 m3/day and at a length of 112.5m, the vessel has been designed for “humanitarian organisations or communities which require a clean supply of water urgently”.
Hyflux’s Kristal ultrafiltration (UF) membranes would be used for the on-board pre-treatment to help remove microorganisms and bacteria.

Electrical power would be provided from multiple generators installed on the vessel, with an energy recovery system also planned to be included.
There are then two reverse osmosis (RO) passes for the treatment of permeate from the UF. Once treated, water is stored in the product water tank before use.
With increasing discharge limits for wastewater and tighter planning obstacles, there is a growing trend for the development of off-shore treatment.

In April Bloomberg reported that Israeli company IDE Technologies was also in talks with Japanese shipbuilders and the government to design off-shore desalination plants.
The April-May edition of Water & Wastewater International (WWi) reported how the Norwegian company EnviroNor is developing a floating wastewater treatment vessel using old oil tankers (read WWi article).
Industry analysts Frost & Sullivan predicted the mobile water treatment market to generate revenues of $895 million by 2016 (read WWi article).

Speaking to WWi, Roland Ang, managing director, business development, said: “The Hyflux floating desalination vessel is a one-stop desalination mobile unit. It’s 30,000 m3/day at top capacity. It’s a whole process on board that includes RO/UF, including water storage.”
Ang suggested the first full scale FDPV could be rolled out in as little as six months, with the first deployment likely in the Middle East.

In the company’s corporate brochure on the FDPV, Hyflux suggested the floating vessel would be well placed to provide water in emergency situations.
It said: “Over the years, rapid climate change and the increase in occurrences of natural disasters globally have posed challenges for humanitarian organisations to provide a secure and clean supply of water to victims quickly.”
