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.

The automatic station for preparation in continuous of solution of polyelectrolyte, is a machine to use in the processes of mechanical dehydration of the sludges obtained from dewatering machines.
Product in powder, before being used for flocculation of sludge to treat, must be diluted in water in such a way to obtain the title of dehydration desired and must be subjected to a process of maturation enough long (min 30/40 minutes).
Polyelectrolyte in powder is loaded inside a hopper equipped with dosing screw, which transports the product to hydrate through a heated piping, permitting it to fall on the device for water diffusion.
The hydrated product is diluted in the first sector by the first mixer then, by the siphon system, it enters into the second sector. In this sector, which is equipped with mixer at low rotations, there is maturation of solution. Through the second siphon, solution goes into the third sector, where there are an additional maturation and also stocking of product ready to be pumped in the line. In the third sector, when required, can be installed both a third mixer and the pump to extract the poly ready.
By level feelers, system of preparation is automatic. Feelers start and stop preparation, when station is completely full in the three sectors. Adjustments of preparation are realized partly distributing flow of dilution water and/or basing capacity of dosing screw, acting on motovariator.

Structure is completely made in bended pressed plate in AISI 304 with edges bended inside, to stiff the structure itself. Partition baffles in bended and stiffened plate, which act as siphon of passage for the solution. Bottom in plate totally welded to plating, with feet of support to floor, which act also as stiffening of the lower part. Superior structure is realized with plates bended and stiffened, used as supports for gearmotors of mixers and for structure of the dosing unit. Are included screwed covers as protection of the dangerous parts.
Doser made in plate in AISI 304 with dosing screw, bridge breaker, bolted closing cover.
