Abstract
A method of treating wastewater, and more particularly stormwater runoff or domestic waste, wherein the wastewater is directed through a high carbon ash particulate. Contaminants such as phosphorus, nitrogen, BOD and COD can be removed. In addition, treatment of the stormwater runoff or domestic waste with ash will raise the pH of the wastewater, generally to above 10, killing bacteria contained in the wastewater.
