ABSTRACT:
Treatment plant for treating a fluid formed by waters and sludges and comprising a decanting system; a first centrifuging system for separating, on the one hand, the spent waters and, on the other hand, the sludges formed by organic compounds containing or not heavy metals and the sludges formed by higher-density mineral compounds; an irradiation device for irradiating, by means of an accelerated electron beam for example, the sludges formed by organic compounds and especially those containing heavy metals so as to convert them into mineral compounds which are less toxic and have a high density; a second centrifuging system for subsequently separating and eliminating these mineral compounds.
