The present invention provides a low energy alternative to conventional thermal/evaporation processes for “zero liquid discharge” treatment of strong saline brines. The products of the process include a salt-free liquid and solid salt. In particular, an antisolvent can be mixed with liquids containing high total dissolved solids. The mixture can be chilled, whereby solid salt is precipitated and separated from the mixture at near ambient temperature leaving a mixed liquor. The antisolvent can be selected from a class of organic compounds that form solutions with salt brines that exhibit a critical solution temperature lower than a critical solution temperature of the salt brines alone. The mixed liquor can be heated to a temperature above its lower critical solution temperature to produce an antisolvent liquid phase for recycle to the process. Finally, a reduced salinity aqueous phase can be polished by reverse osmosis or other conventional technology to produce clean water for discharge or beneficial use. 1.

The present invention is a wastewater treatment method using dried BOF slag and hydrogen peroxide, wherein hydrogen peroxide is oxidized to generate hydroxyl radicals that reacts with soluble metal contaminants in the sludge such that these contaminants can be adsorb on the catalyst particles and/or eliminated from the wastewater stream by separation techniques. The process can use catalytic oxidation for soluble metals removal. In addition, catalytic oxidation can produce a filtered water saturated with Oxygen and higher in pH resulting in enhanced precipitation of soluble metals when softening agents, such as Sodium Carbonate, are added in a subsequent processing step. Another embodiment of the present invention is a method using ferrous sulfate for removing soluble metals in wastewater, followed by Catalytic Oxidation to remove soluble Fe without addition of metal salts, and removing sulfates by adding Barium Carbonate. 1.

A fluid filter is placed in an auxiliary fluid reservoir located in or next to the main fluid reservoir. An ozone generator pumps a combination of ozone and air into the auxiliary reservoir. Fluid in the auxiliary reservoir passes through a filter and back into the main reservoir without the use of any fluid pump. More specifically, a vertical lift tube is placed beneath the auxiliary fluid reservoir so that the open top of the lift tube is within the auxiliary reservoir. Fluid from the main reservoir is fed to the bottom of the lift tube. Ozone and air from the ozone generator is also piped into the lift tube near its bottom. The fluid flows through the filter due to the effect of ozone and air bubbles released by a diffuser at the bottom of the lift tube. The diffuser releases thousands of tiny bubbles into the lift tube, which cause the fluid in the tube to rise and mix with fluid already in the auxiliary fluid reservoir. This rising fluid also causes fluid to flow through the filter. The ozone treated fluid output from the filter is piped back into the main fluid reservoir. 1. A method for ozone-aerating and filtering fluid in a main fluid reservoir , comprising:providing an auxiliary fluid reservoir positioned adjacent to and outside of the main fluid reservoir and coupled to the main fluid reservoir via two conduits, a first conduit for enabling ozone-aerated and filtered fluid in the auxiliary reservoir to flow into the main reservoir by gravity when the fluid level in the auxiliary fluid reservoir is higher than the fluid level in the main fluid reservoir, and a second fluid conduit for enabling fluid to flow from the main fluid reservoir to the auxiliary fluid reservoir;providing a lift tube extending below the auxiliary fluid reservoir, said lift tube having a lower end connected to the second fluid conduit and an upper end ...
