20. The method of claim 1, A method of water treatment comprising:
providing water comprising at least one contaminant;
adding a geopolymer filter media to the water;
agitating the water comprising at least one contaminant and the geopolymer filter media to form a homogeneous mixture;
adsorbing the at least one contaminant from the water onto the geopolymer filter media;
adding a cationic biopolymer to the homogeneous mixture of water and the filter media;
coagulating the geopolymer filter media and the at least one contaminant with the cationic biopolymer to form coagulated flocs; and
separating the water from the at least one contaminant and the geopolymer filter media by settling of the coagulated flocs;
wherein the geopolymer filter media comprises aragonite, bentonite, and zeolite in a ratio of one part aragonite, two parts bentonite, and one part zeolite.
