Abstract

An apparatus and method for converting seawater to drinking water at room temperature aoci normal atmospheric pressure. The conversion is accomplished using the processes of osmosis, ammonia stripping: ion exchange, and breakpoint chlojlnation, which provide a low-cost alternative to traditional seawater conversion methods.
