A method for complex procesing of sea-water comprises the successive steps of mechanical filtration, calcium separation on modified zeolite, magnesium separation on weak-acid cation exchanger and processing of the resulting softened sea-water, regeneration of the modified zeolite and regeneration of the weak-acid cation exchanger. During the step of processing of the softened sea-water, its desalination it carried out so as to produce fresh water and simulatneously produce secondary brine having a concentration of salts at least as high as 100 g/l whereby the modified zeolite is regenerated. A plant for implemention of the method of complex processing of sea-water comprises a filter, two sorption columns for calcium separation connected in parallel with each other, a sorption unit for magnesium separation, a softened sea-water processing unit and a mixed concentrate processing unit.
