Seawater is a storehouse of chemicals and contains more than 73 elements in dissolved state. Coastal locations have abundant seawater whereas landlocked areas do not have seawater.  Yet seawater may be required in the latter areas too for diverse purposes.  Since transporting seawater is a costly and difficult proposition, many efforts have been made to constitute compositions, which mimic seawater.  However, these are not exact replica of seawater and in that sense; they are non-standard compositions, which vary from formulation to formulation.  The only thing that appears to be common to all is their prohibitive cost, which further limits the scope of such seawater applications in locations not blessed with a coastline. 

Similarly, fresh water is what we drink and use for agriculture.  In many instances, the water is severely deficient in nutritious minerals, particularly the water obtained from desalination plants.  Indeed, it is unfortunate that the desalination process not only drives out sodium chloride but also essential minerals and in cases such as reverse osmosis based desalination, these are preferentially driven out making a bad situation worse.  Although the problem can be mitigated through re-mineralization, many plants do not practice re-mineralisation due to the additional cost involved, particularly the high cost of the nutrient salts.

The process involves the fractionation of seawater into three fractions which can thereafter be suitably combined to reconstitute seawater in its pristine form for its various applications such as growth of marine microbes, flora and fauna in a marine environment, especially where such environments have to be created in locations far removed from the sea and/or where there is a requirement to modify the composition of seawater to better its performance.  The fractions can also be blended appropriately to exclude the major constituent, namely sodium chloride, and thereby be useful for mineralization/re-mineralization of waters which are deficient in mineral nutrients such as calcium, magnesium, potassium, sulphate and bicarbonate including rain water and desalinated waters obtained through thermal/RO desalination. The invention can be practiced most cost-effectively in solar salt works operated on sea brine. 

This is an eco-friendly process.
