Title (EN) CLARIFICATION TREATMENT APPARATUS AND METHOD FOR CLARIFICATION TREATMENT
(FR) SYSTEME DE CLARIFICATION ET PROCEDE CORRESPONDANT
Abstract:
(EN) A clarification treatment apparatus (10) comprising a first agitator (14) for mixing a material to be treated such as a sludge from a sewage treatment tank with coke and optionally an appropriate aid, a second agitator (18) for mixing the material to be treated with a flocculant, a dehydrator (24) and a dryer (26). Due to the agitation by the first agitator, pollutants in the material to be treated is efficiently adsorbed on the coke. The mixing of the material to be treated with a flocculant forms flocks, which are then efficiently dewatered by both pressurization and suction in the dehydrator. The resultant dewatered cake is charged to the dryer together with an oil and heated for drying, thereby producing a fuel having a high calory.
(FR) Ce système de clarification (10) est pourvu d'un premier agitateur (14) servant à mélanger les matières à traiter, notamment une bouillie issue d'une cuve de traitement d'eaux usées, à du coke et éventuellement à un produit d'addition, d'un second agitateur (18) servant à mélanger les matières à traiter à un agent floculant, d'un déshydrateur (24) et d'un sécheur (26). Du fait de l'agitation produite par le premier agitateur, les polluants présents dans les matières sont efficacement adsorbées sur le coke. Le fait de mélanger les matières à traiter à un agent floculant produit des flocons qui sont efficacement déshydratés tant par mise sous pression que par aspiration dans le déshydrateur. Le pain déshydraté résultant est transféré avec une huile dans le sécheur et chauffé aux fins du séchage, ce qui permet de produire un combustible à pouvoir calorique élevé.
