A method and composition for treating wastewater streams is provided. The composition includes a zirconium salt and preferably a zirconium carbonate. In addition to the zirconium salt; a ferrate, a reducing agent, a weighting agent and an anionic coagulating agent can also be employed. The method includes the steps of adjusting the pH of a wastewater stream to between about pH 6.5 and about pH 14, adding the composition, precipitating contaminants from the wastewater stream and separating a solution having a reduced contaminants content therefrom.
