Abstract

Water distillation is a high-energy process requiring expensive machinery and large amounts of capital to create facilities. Because of the high costs of distillation, research was conducted on membranes consisting of cellguard pp2068 and hydrophobic carbon cloth. These filters require less complex infrastructure to put in place making them cheaper. In this experiment water was heated on one side of the membrane, water vapor passes through but liquid water cannot. Due to this property water was to be distilled to a high quality but low energy input in total compared to reverse osmosis. Salt water was heated on one side and the output was collected on the other for an hour per test. On average 5.5 millimeters were collected and there was appreciable salt rejection by the membrane meaning it was very efficient at contaminant rejection.
