If you desire to purify seawater, use a water maker as pre-filter to the Aquablu purifier.
A way saline water is desalinized is by the "reverse osmosis" procedure. In most simplistic terms, water, containing dissolved salt molecules, is forced through a semipermeable membrane (essentially a filter), in which the larger salt molecules do not get through the membrane holes but the smaller water molecules do.
Our technology is an upgraded version of Reverse Osmosis - namely Supreme Osmosis. Currently, Aquablu is able to treat brackish water up to a level of 1200 ppm. So, this does not include direct seawater purification. If you desire to purify seawater, use a water maker as a pre-filter to our system.
