Abstract: A method of waste water treatment including mixing waste material with a binder, pelletizing the mixture and kiln incineration of the pellets to ceramify same, with processing of flue gases. In an embodiment, the pH of the mixture is maintained alkaline. In an embodiment, the pelletized mixture is coated with ball clay to 10-20% by weight, and then with china clay, prior to firing. The high temperature flue gases and entrained heavy metal or dust exhausting the kiln are directed through a multistage scrubbing system. In an embodiment, volatiles are adsorbed prior to the gas passing through an alkali wet scrubber to remove chlorine compounds and heavy metals, and sulphur compounds. The sludge from the acid scrubber is neutralized and further treated to remove mercury.
