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.
