I dissabbiatori e i disoleatori trovano applicazione negli impianti di depurazione che trattano effluenti di reti miste.
La disoleatura 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.

La rimozione degli oli, grassi e schiume che si concentrano sulla superficie libera del refluo e la rimozione della sabbia sul fondo si rende necessaria per evitare i problemi all’interno dei successivi bacini di decantazione e di digestione.

Sand classifier is a machine used to separate, by settlement, sand from water. Mixture of sand and water enters into settling hopper. Here, by gravity, sand and other organic substances settles on bottom of machine. A screw removes and transport sand and organic substances settled, till the point of discharge.
Clarified water exits through a surface weir, which is inside settling hopper.

Bearing structure in cold bent-pressed plate in AISI 304.
Settling hopper is designed in way to avoid clogging of material inside. Hopper is equipped with deflector and weir for settled water.
Trough is made in AISI 304 stainless steel. Wear flat bars in AISI 304 are easily replaceable.
Transport screw is in carbon steel FE 510 with paint. It is made by flat bar of big thickness suitably shaped.
Worm screw gearmotor directly coupled to the screw.
