아랍에미리트 최북단에 위치한 Ras Al Khaimah는 적조 현상을 극복하기 위해 에미리트 항공 서쪽 해안선에서 하루 68ML 규모의 Ghallilah 해수역삼투(SWRO) 프로젝트를 시작했다.

이번 프로젝트는 에미리트 서쪽 해안가 유해 해조류(HABs)의 규모가 나날이 증가해 해수 내 불순물을 제거하는 전처리 필터를 손상시키고, 역삼투막으로 스며들어 역한 맛과 냄새를 발생시키는 상황에서 이를 막기 위해 실시됐다.

 

 

 

Northernmost of the United Arab Emirates (UAE), Ras Al Khaimah, has opened a 68 Ml/d seawater reverse osmosis (SWRO) project in Ghallilah on the emirate's west coast that is equipped to "overcome the red tide phenomena" - the seasonal proliferation of algae that blights the emirates' coastline.

 

The Dhs 320 million (US$ 87.1 million) facility was built by Aquatech for the Federal Electricity and Water Authority (FEWA) under a engineering-procurement-construction deal awarded following competitive tender in 2011. The contract included civil works, buildings and electrical and mechanical installation.

 

The scale and impact of harmful algal blooms (HABs) are rising. HABs clog pre-treatment filters and and foul and damage reverse osmosis membranes as well as create bad taste and odour in the permeate.

 

Dissolved air flotation pretreatment is included in the Ghallilah plant to tackle algal blooms following pilot studies were by FEWA. The plant uses 4,788 Toray SWRO membrane modulars with X-Flow ultrafiltration membranes by Pentair.
