Making use of Earth’s biggest resource: a quantitative look at ocean water purification Smyth, Matthew
Three methods of simple sea water purification were examined and compared to one another to find the most effective and the most efficient way of lowering the salt levels of sea water. Water filtration using a Brita filter was least effective, but very efficient. Freezing the water was effective in cutting the water down to below a third of its initial salt concentration, while distilling the water was most effective, and required the most amount of energy.
