Watermaker- The principle
Sea water (or other foul water source) is introduced into a pressure containment vessel and is exposed to a membrane which has interesting properties in that its structure is semi permeable allowing molecules of water to pass through, but not salt, mineral contamination, bacteria or pryons. Perhaps the electronic equivalent may be the semiconductor that drives the computer monitor screen you are looking at right now.
Reverse osmosis is the most energy efficient method for a watermaker, however it does require relatively high pressures. The failure of a watermaker pressure vessel in a confined space could have serious consequences. Like divers cylinders, this is a very rare occurrence, nonetheless, pressure containment vessels must be treated with respect - even a Waterlog.....
Because a Waterlog is towed some 10M (30 feet) behind the boat, the high pressure energy never comes near the vessel or crew.
A Waterlog watermaker is built in solid stainless steel, including the pressure casing. Completely self contained, this watermaker pumps pure water aboard.
