Composition, system and method for removal of detergents from aqueous solutions

A method of removing a detergent from an aqueous solution comprising said detergent, said method comprising the step of mixing the aqueous solution with:

• a. a salt;
• b. a water immiscible alcohol of Formula I
• R1—OH (Formula I)
• where R1 is an optionally substituted, linear, branched or cyclic C4-C12 alkyl;
• and
• c. a water immiscible halocarbon, wherein said halocarbon is miscible with said alcohol of Formula I,
• to form a two-phase mixture comprising an aqueous phase and a non-aqueous phase, wherein more than 99% wt/vol of the detergent is in the non-aqueous phase;
• and
• wherein the halocarbon is present at a concentration sufficient to increase the density of the non-aqueous phase to greater than the density of the aqueous phase, wherein the concentration of halocarbon in the alcohol is up to 80% (v/v),
• wherein the ratio of the total volume of the salt plus the alcohol plus the halocarbon to the volume of the aqueous solution comprising the detergent is from 1:9 to 2:1.
