Franchini S.p.A. Servizi Ecologici specialises in the treatment of civil and industrial wastewater treatment sludge.
Franchini S.p.A. deals with the dewatering of biological sludge, digested sludge, drinking water sludge, drilling sludge, sludge from washing inert materials and primary sludge. The proposed service consists in the dewatering of pumpable sludge produced by wastewater purification processes, carried out by means of mobile plants positioned directly at the customer's purification plant.
Franchini S.p.A.'s mobile plants are all of very recent construction, designed in-house and characterised by high technological content and high treatment potential.
The objective of sludge desanding is to effectively remove sand and inert solids, normally heavier than the organic components, present in sewage sludge and sludge deposited at the bottom of sewage plants.
Sludge screening consists of a coarse mechanical filtration operation, to 5 or 10 mm, with the aim of retaining non-settleable coarse solids (rags, plastic, etc.) and settleable coarse solids (gravel, etc.) present in sewage water and sludge. Franchini S.p.A. Servizi Ecologici is able to take care of this phase of primary importance in the ordinary and extraordinary maintenance of technical artefacts included in the wastewater purification cycle.
