담수생산량 향상을 위한 흡착제 합성 및 흡착등온선 실험

Abstract

Reverse osmosis and evaporation methods, which are typically used for seawater desalination, have disadvantages such as large energy consumption and regular additional costs, so a new seawater desalination method is required. 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.
