摘要： The present invention provides a composition in dry form, preferably in the form of a tablet, containing a combination of ingredients which upon addition to contaminated water effectively removes turbidity, metal and organic contaminants in the water and thereby makes the water safer for drinking. The composition is particularly useful for personal use so that safe drinking water can be obtained by the simple addition of the composition to the water to remove the turbidity and contaminating materials contained therein. Preferably the composition contains bentonite clay, attapulgite clay, polymeric coagulant and/or flocculent, biocide, zeolite and activated charcoal. The invention also provides a method for treating water with the composition as well as a method for making the composition.
