A personally portable water purification compound prepared in unit dosage form such as tablets, packages and the like and having titanium dioxide (TiO 2) in the form of fine particles, and adsorbed chlorine held at the surface of the titanium dioxide particles; and a titanium based coagulant; the compound bei ng prepared in a plurality of unit dose size packages, for personal use by individuals. Also disclosed is a method of preparing a personally portable water purification compound consisting of the steps of heating titanium dioxide particles up to a temperature between about 260-500.degree.C, passing a cold dry gaseous chlorine flow around the titanium dioxide particles; and cooling the titanium dioxide duri ng the treatment. Also disclosed is a method of purifying water containing contaminants and bacteria consisting of the steps of segregating a predetermined volume o f the water, introducing a first predetermined quantity of titanium dioxide particles activated with adsorbed chlorine, simultaneously introducing a second predetermined quantity of a titanium coagulant, agitating the water and releasing the chlorine from the titanium dioxide particles, the chlorine destroying th e bacteria, allowing the water to stand for a predetermined dwell time, during which the titanium dioxide without chlorine attracts contaminants, and after which the titanium coagulant forms flocs into masses heavier than water which masses settle out, leaving the water purified.
