Abstract
A method of treating domestic wastewater 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 domestic waste with ash will raise the pH of the wastewater, generally to above 10, killing bacteria contained in the wastewater.
Claims20
A method of treating domestic wastewater comprising directing the domestic wastewater into a domestic wastewater treatment system and treating at least a portion of the domestic wastewater by contacting the wastewater with ash, and wherein the ash removes pollutants from the domestic wastewater;
- and wherein directing the wastewater into a wastewater treatment system includes directing the domestic wastewater into a septic system and treating the wastewater in the septic system and thereafter directing the wastewater through a polishing unit including the ash and contacting the wastewater with the ash.
A method of treating domestic wastewater comprising directing domestic wastewater into a domestic wastewater treatment system and treating at least a portion of the domestic water by contacting the wastewater with ash, and wherein the ash removes pollutants from the wastewater;
- and wherein the method includes directing the domestic wastewater into a septic system and treating the wastewater in the septic system;
- and wherein the method includes placing the ash into a tank and directing the domestic wastewater into the tank and filtering the wastewater downwardly through the ash.
A method of treating domestic wastewater comprising:
- a. directing the wastewater into a septic tank;
- b. directing effluent from the septic tank to a tank having ash comprised of coal ash produced from a power plant boiler or coal burning furnace and ash produced from a tire derivative fuel or wood;
- and
- c. directing the wastewater through the coal ash and removing from the wastewater one or more contaminants selected form the group including phosphorus, nitrogen, BOD and COD.
A method of treating storm water runoff comprising:
- a. directing the storm water runoff into a sand cleaning device and cleaning sand from the storm water runoff;
- b. after removing the sand from the storm water runoff, directing the sand to a treatment chamber having an ash chamber separated from an outlet section by a vertical baffle spaced above a bottom of the treatment chamber;
- c. treating the storm water runoff in the ash chamber by directing the storm water runoff downwardly through coal ash disposed in the ash chamber;
- d. removing nitrogen, phosphorous, BOD and suspended solids from the storm water runoff by contacting the storm water runoff with the coal ash;
- e. after treating the storm water runoff with the coal ash, directing the storm water underneath the baffle and into the adjacent outlet section of the treatment chamber;
- and
- f. directing the treated storm water runoff out the outlet section of the treatment chamber.
