Sludge screening

Removal of bodies and gross objects from wastewater and sludge

Sludge screening consists of a coarse mechanical filtration operation, at 5 or 10 mm, with the aim of retaining non-sedimentable coarse solids (rags, plastic, etc.) and sedimentable coarse solids (gravel, etc.) present in sewage water and sludge.

Franchini Servizi Ecologici is able to handle this primarily important phase in the ordinary and extraordinary maintenance of the technical devices included in the purification cycle.

Sludge screening can be used and particularly recommended in the maintenance phases of the technical devices present in purification plants but also for classifying the sludge present in anaerobic digesters, tanks, and compartments purification.

This activity allows for the correct separation of the various phases directly on site, thus reducing waste disposal management costs.
