STATIC GRID

MEDIUM AND FINE SCREENING

La grigliatura delle acque reflue è uno dei trattamenti meccanici preliminari a cui vengono sottoposte le acque di scarico all’ingresso degli impianti di depurazione per rimuovere e ridurre i materiali sospesi e galleggianti.

In alcuni casi particolari, come per le acque di pioggia o lo scarico a mare, tali trattamenti non hanno carattere preliminare, ma possono costituire l’unico intervento prima della dispersione dei reflui nell’ambiente. La grigliatura è normalmente la prima di questi trattamenti, e ha come scopo principale la rimozione di corpi e oggetti grossolani.

In particolare, la grigliatura permette di evitare danneggiamenti alle sezioni di impianto successive, ad esempio le pompe utilizzate per sollevare e spostare il liquido, e ridurre l’accumulo di solidi nelle tubazioni.

Sewage to be treated is fed by a pump or by gravity inside the feeding tank of the machine and overfill in the top part of the filtering surface.
The special grids that form the filtering surface keep the solids with dimensions larger than the filtering spacing and let flow through the water that is collected and conveyed outside of machine by the discharge tube.
Due the gravity the solids slide on the filtering surface and reach the discharge chute where can be collected in suitable containers.
To treat particular kinds of sewage that use to obstruct the filtering surface is possible to have the machine provided of an optional device to clean the grids by pneumatic brushes.

The machine is composed of a bearing structure including feeding and collecting tank with flanged inlet and outlet attachments.
The filtering surface consists of a frame and special grids.
Filtering surface with adjustable inclination and with complete overturning for the cleaning operation of the machine.
Optional device for cleaning of the filtering surface. It is made by two brushes mounted on a guided frame moved by a pneumatic cylinder.
