WATER PURIFICATION COMPOSITION

摘要

The invention relates to a water purification composition. The invention particularly relates to a water purification composition that is especially useful for removal of trace quantities of harmful heavy-metal contaminants like Arsenic, in addition to removal of micro-organisms like viruses, bacteria and cysts to make the water suitable for human consumption. It is an object of the present invention to provide a coagulant composition for purification of water that provides for removal of at least 90% Arsenic, and 6-log bacteria, 4-log virus and 2-log cysts from contaminated water. The present inventors have found that an aqueous composition which includes Aluminium salt; Iron salt; Potassium permanganate, in define ratios meet the above objects.
