<p>The ash is stored on a platform and matured. A strong leachate produced by the ash is passed from sealed troughs to a retention container, where it is air-oxidized to reduce organic pollutants. The aerated leachate is then pumped to a treatment unit. The treated leachate is stored in a tank or an intermediate reservoir, before being fed with ash and an hydraulic binder to a mixing unit. The strong leachate is treated by single-stage reverse osmosis and/or evaporation and condensation in the treatment unit. Concentrate resulting from treatment of the leachate is discharged into a specialized supply system. Air oxidation of the leachate is carried out with aerators, preferably using a pump connected to at least one hydro-ejector. Treated leachate from the intermediate reservoir is sprayed onto the ash stored on the platform by spray guns. An Independent claim is given for an assembly that utilizes the treated leachate.</p> |
