Abstract
A sea water harvesting process includes the steps of collecting sea water, filtering the sea water, passing the filtered sea water through a high-pressure reverse osmosis membrane to separate the sea water into de-salinated water and concentrated sea water, delivering the concentrated sea water to an evaporator, heating the concentrated sea water in the evaporator under vacuum to produce calcium sulphate, sea salt and a super-concentrated sea water. Downstream of the evaporator the super-concentrated sea water is heated to produce a concentrated mineral liquor containing sea minerals in a concentration of about 42%.
