The present invention relates to a novel biocide composition for use in gravity fed water purification devices and suitable for purifying water for drinking purposes and a process for preparing the novel biocide composition. The biocide tablet composition comprises one or more halogenated 5, 5-dialkylhydantoin compound; a chlorine biocide compound selected from trichloroisocyanuric acid (TCCA) or sodium dichloroisocyanurate (NaDCC) or mixtures thereof; 0.1-1.0% water soluble boron containing compound; wherein the ratio between the halogenated 5, 5-dialkylhydantoin compound and chlorine biocide compound is in the range 85:15 to 65:35 and the average particle size of the halogenated 5, 5-dialkylhydantoin compound and chlorine biocide compound is in the range 400 to1200 microns.
A biocide tablet composition comprising:
A biocide tablet composition as claimed in wherein the water soluble boron containing compound is boric acid.
A process of preparing a biocide tablet comprising
A process of preparing a biocide tablet as claimed in claim 9 wherein the temperature during the process is in the range from 15 to 30° C.
