ABSTRACT:
A composition, in unit dosage form, for the batchwise purification for drinking purposes of a relatively small predetermined volume of contaminated water includes: (a) an organo-chlorine compound serving as a disinfectant-sanitizing agent; (b) a solid inorganic metal salt having a trivalent cation serving as a coagulant-precipitate agent; (c) a solid alkali which is highly soluble in water and highly effervescent in the presence of an acid serving as a dispersion-buffer agent; (d) a solid anionic polymeric hydrophilic primary colloid flocculant; (e) a solid cationic, polymeric hydrophilic secondary colloid flocculant; (f) long fiber cellulose serving as an agglomeration matrix and pre-filter for absorbing flocs and trapping visible debris and cysts; and (g) a bulk ion exchange absorbent. A water purification kit and method employing the composition are also disclosed.
