VERTICAL CYLINDRICAL REACTOR

SLUDGE TREATMENT

L’ultima fase funzionale di un trattamento di depurazione è il trattamento dei fanghi, il cui obiettivo è quello di migliorare la qualità del rifiuto finale in modo da smaltirlo correttamente o riutilizzarlo

Il fango di risulta di un impianto di depurazione, quando non è più riutilizzabile internamente, segue una serie di operazioni dette trattamento dei fanghi. In questa fase i fanghi che contengono quasi tutto il BOD residuo e che, a causa della presenza di rilevanti quantità di materiale batterico, sono altamente putrescibili, vengono stabilizzati in modo da renderli idonei al successivo essiccamento e smaltimento.

L’obiettivo finale del trattamento dei fanghi è quello di rendere migliori le caratteristiche del fango affinché possa essere correttamente smaltito come rifiuto oppure (solo se rispetta determinati requisiti) riutilizzato in agricoltura.

Vertical cylindrical reactor of series CV, is a unit necessary to mix polyelectrolyte with sludge, before sludge is loaded on the feeding hopper of belt press, or on dynamic thickner with rotating drum. Reactor is composed by a cylindrical tank, fitted with an electric mixer at low number of rotations, to achieve the best mixing and sludge flocculation.The long time of contact sludge-poly, due to the volume of the CV, before sludge is unloaded on belt press, ensures optimal efficiency of flocculant, reducing consumption of polymer and optimizing the efficiency of belt press, both in terms of flowrate and in terms of dryness in exit. Cylinder is equipped with two lower flanges, one for feeding of sludge and polyelectrolyte, the other (on the opposite side) for cleaning and maintenance. The discharge opening, which has rectangular shape, directly unloads material on belt press.

Bearing structure in cold bent plate, in hot galvanized steel, with bottom plate with holes, to permit fixing to floor by anchoring bolts. Are also included closing cover and support of gearmotor.
Gearmotor with variator of rotations and mixer, composed by shaft with electro-welded paddles, for mixing of sludge with poly.
Inner lateral blades to break flow.
Discharge opening with rectangular shape, equipped with drip flap, to avoid leakage of water.
Flanges for feeding and emptying made in hot galvanized steel.
