In contrast, the adsorption desalination (AD) technology can simultaneously produce three useful effects (high concentration concentrated water, high purity fresh water, and cold water for cooling) using a low temperature (< 80°C) heat source. And, since it is operated at low temperature (< 30°C) and low pressure (< 10 kPa), it is possible to minimize the occurrence of fouling and scale compared to existing seawater desalination technologies (MED, MSF, RO). Accordingly, it is an environmentally friendly seawater desalination technology that can minimize the use of chemicals in the pretreatment process. In this study, a synthetic silica gel was prepared and performance evaluation was performed to improve the freshwater production and performance of the adsorption desalination method. 2021-12-03T00:00:00Z https://www.kriso.re.kr/sciwatch/handle/2021.sw.kriso/7508 Title: 진공 막증류장치(VMD)를 이용한 해수농축 시스템 성능평가 실험 Abstract: The production technology of mineral salts and extracts from deep seawater has been required for high value-added industries. To meet this demand, the VMD (Vacuum Membrane Distillation) system was applied and improved to achieve seawater concentration by 11% and reduce power requirement. An experiment using a pilot system was performed, and it was possible to concentrate seawater to 11% or more. Also, the composition of the concentrated and permeate water was found to be satisfactory for industrial application. 2021-12-03T00:00:00Z https://www.kriso.re.kr/sciwatch/handle/2021.sw.kriso/1933 Title: 네트워킹-해양수산 국제협력의 과거와 미래 Authors: 김현주 2021-03-01T00:00:00Z https://www.kriso.re.kr/sciwatch/handle/2021.sw.kriso/1931 Title: 지구과학과 지속가능 발전 목표 Authors: Michael Petterson; 김현주; Joel C.
