독일 화학 회사인 Lanxess는 이집트 Sharm에서 실시된 RO 멤브레인 테스트에서 고품질의 물을 생산했다고 밝혔다. Lanxess는 새로운 Lewabrane RO S 멤브레인을 테스트하기 위해 Deutsche MeerwasserEntsalzung (DME) GmbH와 계약했다. 관리 책임 기술자인 Claus Mertes는 " 이 부품은 실제 운영에서 산업 기준을 충족한다."고 발표했다.

이 부품은 2014년부터 이집트의 상·공업 규모의 담수화 플랜트에서 테스트를 진행해왔다. 비슷한 조건과 모든 요구되는 공정 변수에 따라서 시험한 결과 고품질의 물 생산에 성공했다. Lanxess는 이 부품을 the Singapore International Water Week에서 출시한다고 설명했다.

Prior to launching its new line of reverse osmosis (RO) membranes, German chemicals company LANXESS said an “excellent water quality” was produced from the elements in a test run in Sharm El-Sheik, Egypt.

Deutsche MeerwasserEntsalzung (DME) GmbH, a Duisburg-based company were contracted by LANXESS to conduct the tests on the new Lewabrane RO S membranes.
Managing director engineer Claus Mertes said the elements “meet or exceed the relevant industrial standards in continuous operation (24/7) under real conditions. They show high salt rejection even under fluctuating temperatures, salt contents and pH values, meaning that they deliver permeate in consistently high quality”.

 

The elements have been undergoing testing in Egypt since March 2014 in a commercial, industrial-scale desalination plant. Under otherwise comparable conditions and in compliance with all required process parameters, an excellent water quality was achieved at a high permeate flow, according to the chemicals company.

Following the test results, LANXESS launched the vessels at the Singapore International Water Week.

Three different elements are currently available: Lewabrane RO S400 HR, S440 HR and S085 HR 4040. The first two are 1,016 mm (40 in.) long with a diameter of 201 mm (8 in.), and have a membrane area of 400 and 440 square feet, suitable for use in all standard RO facilities. The third grade has a diameter of 101 mm (4 in.) and is suitable for smaller systems.
