PRINCIPLE

This rotating sieve separates continuously solid particles in suspension in a fluid. The suspension 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 placed inside the drum.

DESIGN FEATURES

The filtering drum is made of stainless steel triangular section wires: this wire allows the obtaining of a very favorable hydrodynamic flow coefficient, from the exterior towards the interior. It facilitates the cleaning of the grid from the inside towards the outside.

Rolling up is carried out by a 0,25 to 10 mms spacing out between wires, depending on the fineness of the required filtration.

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 moto-reductor with a speed of rotation adapted to the diameter of the drum. A moto-variator is available as an optional extra.

Dimensions of the sieve - diameter, length, standard or short height - as the positions and the dimensions of the input/outputs, can be adapted to your needs.

The flanges of the drum are largely openwork in order to facilitate a direct access inside the drum.

The jets of the spray bar are in polypropylene plastic to suppress any risk of galvanic corrosion.

APPLICATIONS

 SERTAM rotating sieves have a universal application, either in sewage treatment, or in process, for all the urban purification stations and industries (canning facilities - slaughterhouses - cheese dairies – wine industry - chemistry - pharmacy - etc).

Examples

- Filtering of used water before rejection to the sewer or before additional treatment

- Cleaning of vegetables and fruits - Sifting of oil - Recovery of cellulose fibres - etc.

ADVANTAGE

·        Simple and robust system functioning without monitoring

·        In the case of application in process, possibility of having several interchangeable sieves with different slots

·         In the case of treatment of wastewater, reduction of the suspended matter and biochemical and chemical oxygen demand (BOD and COD), allows a rapid pay back by the savings made on the pollution fees

To usefully supplement SERTAM rotating sieve, SERINOL also offers:

- Its waste compactor machine SERCOMP

- Its oil skimmer DAR or its flotation unit FLOT T
