The Efficiency of the Cold Trap Condenser in a Pervaporation Membrane Process

Pervaporation is promising a membrane process for purification of highly saline waters beyond the capacity of conventional processes such as reverse osmosis. This project is specifically studying the efficiency of the cold trap condenser used for the system to collect the purified water. It is unknown whether the current cold trap method is the most efficient for water capture. A pervaporation system was modified to isolate the cold trap and study the efficiency of water vapor capture. Initial studies showed that the system was not properly sealed, so a new study began with a modified system.
