rotary sieve with external supply - SERTAM
PRINCIPLEThe SERTAM rotating sieve separates continuously solid particles in suspension in a fluid. The flow is distributed on a filtering drum; the particles larger than the openings are retained then scraped away and recovered.
A continuous cleaning is ensured by the filtered water, which crosses the drum from the interior towards the exterior.
A more thorough intermittent cleaning is carried out by a spray bar, supplied by the tap water system, with flat jet nozzles installed inside the drum.
The filtering drum is made of stainless steel triangular section wires (Johnson's mesh): this wire allows a very favourable hydrodynamic flow coefficient, from the exterior towards the interior. It facilitates the cleaning of the grid from the inside towards the outside.
Openings available are 0.25 to 2.5 mm.
The scraper is made out of a brass blade, fixed on a stainless steel articulated chute which position in relation to the drum, is manually adjusted.
The drive is ensured by a geared motor with a rotation speed adapted to the diameter of the drum. A variable speed motor is available as an optional extra.
APPLICATIONS & BENEFITSSERTAM rotary sieves have so many applications either in sewage treatment, process, in urban or industrial treatment plants (food industry- slaughterhouses - cheese dairies – wine industry - etc).
Its design is simple and rugged, operating without permanent monitoring and requires low maintenance.
