Patent ID: 8523487

Claim:
A method for disposal of a desalination concentrated brine waste product comprising: at a desalination plant, desalinating saline water from a saline water body using a desalination process selected from the group consisting of distillation desalination and reverse osmosis to form fresh water and a desalination concentrated brine waste product, receiving at a pump station present on a surface of an earth body, a quantity of said desalination concentrated brine waste product from said desalination plant; receiving at said pump station a quantity of carbon dioxide waste product from a carbon dioxide source; injecting from said pump station a quantity of said desalination concentrated brine waste product and a quantity of carbon dioxide waste product through an earthbody surface layer having a depth of at least several hundred feet; an intermediate layer comprising rock formations, said intermediate layer being beneath and in contiguous contact with said earthbody surface layer, and penetrating for a depth of several thousand feet into said earthbody; an impermeable layer formed of impervious rock materials, said impermeable layer providing an impermeable barrier to up-flow of liquid materials and gaseous materials and being beneath and in contiguous contact with said intermediate layer, and penetrating for a depth of several thousand feet into said earthbody, and ultimately into a porous rock formation, said porous rock formation being beneath and in contiguous contact with said impermeable layer including an aquifer being operatively connected to said pump station, wherein separate quantities of said desalination concentrated brine waste product and said carbon dioxide waste product are successively injected to prevent intermixing of said desalination concentrated brine waste product and said carbon dioxide waste product until reaching said porous rock formation including said aquifer, wherein when reaching said porous rock formation including said aquifer, said desalination concentrated brine waste product and said carbon dioxide waste product being mixed to form a mixture having a greater density than a saline material that provides said aquifer, wherein said mixture of said brine waste product and said carbon dioxide waste product sinks to a bottom of said aquifer.
