초록

식수의 보급이 원활하지 않은 경우를 대비하여 저에너지, 자급형 휴대용 담수화 장치를 설계하고 실험하여 그 활용 가능성을 제시하였다. 장비 구성이 단순한 정삼투 현상을 이용하여 휴대용 담수화 장치를 설계하였으며 중탄산암모늄을 이용하여 적은 에너지원을 이용한 담수화가 가능하도록 하였다. 여러 농도의 중탄산암모늄 수용액과 염화나트륨 수용액을 각기 사용하여 휴대용 담수화 장치의 담수화 성능을 조절할 수 있음을 확인하였다. 염 제거 실험을 통하여 음용 가능한 물을 확보하였고 온도를 증가시킴에 따라 그 시간을 단축시킬 수 있음을 확인하였다.

This study aims to design a portable desalination device and discusses the feasibility of the device for overcoming a shortage of safe drinking water. A low-energy, self-supporting, and portable desalination device is designed based on forward osmosis (FO) using an ammonium bicarbonate solution. Experiments with various concentrations of ammonium bicarbonate solution and sodium chloride solution showed that the portable desalination device's performance such as volume and flow rate of desalting water and time required satisfied drinking water standards. The device performance is controlled by varying the concentration and temperature of the solution.
