A method of treatment of wastewater or water where the wastewater/water to be treated is first mixed with wood ash at a ration of 0.278 kg of ash per m<3> of wastewater/water. The resulting wood ash leachate is first allowed to settle to remove larger debris before it is subjected to electro-coagulation to remove color. The detention time of leachate during electro-coagulation is kept at a maximum of one minute to ensure minimal power consumption. Further to this, the ratio of electrode surface area to volume of water is kept close to 0.0645 m<2>/m<3>. |
