Abstract
A composition for treating waste water comprising Natrolite [Na.sub.2 Al.sub.2 Si.sub.3 O.sub.10. 2H.sub.2 O] from 30 to 40 weight %, Montmorillonite from 20 to 30 weight %, Calcium hydroxide [Ca(OH).sub.2 ] from 20 to 30 weight %, Aluminum sulphate [Al.sub.2 (SO.sub.4).sub.3. 7H.sub.2 O] from 1.5 to 3.5 weight % and Magnesium oxide catalyst agent from 10 to 15 weight percent. The composition is effective in treating waste water containing various heavy metals, particularly, Cu, Ni, Zn, Fe, Pb, Cr.sup.6+ and cyanide and in deoderizing and decreasing chemical oxygen demand (COD).
