태양열 해수담수화를 위한 진공 막 증발법 모듈의 해수 공급 조건에 따른 담수 생산 특성

다국어 초록 (Multilingual Abstract)

In this study we built a lab scale VMD (Vacuum Membrane Distillation)system with a capacity of 1 m³ per day. The basic design data of the solar desalination plant, (freshwater production system) using a VMD module exhibited reduced energy requirements compared to other membrane distillation methods, as well as a relatively high production rate, and analyzed the performance characteristics of the VMD module under various sea water temperature, flow rates and salinities.
The VMD module used in this study has an energy requirement of about 24.2 kWh per hour to produce 1 m³ of fresh water over a period of 24 h, The total heat input required for this production is about 580 kWh. The equation of permeate flux according to the quantity of heat input is y = 0.2621x + 1.2384, so that the permeate flux is increased as the quantity of heat input is increased. When salinity or flow rate of the feed water increases, the RR (Recovery Ratio) value is reduced. If the temperature of feed water increases, the RR value is increased.
