Sewage treatment plant – Augusta

The plant is part of the Industrial Development Area of Siracusa-Augusta and, therefore,

easily reached via the road network of the I.D.A., well connected to the highway Catania-
Gela.

The platform is designed to treat organic, urban or agribusiness liquid waste and
industrial liquid waste (mostly from the poles of Eastern Sicily), such as leachate,
galvanic and photographic water, etc.
The plant architecture provides the ability to treat wastewater of a different kind on
separate lines: the first, indeed will be dedicated to the treatment of sewage with a
high organic load (such as waste of the food industry and the spoils of septic tanks) ,
for which there are provided a screening and initial grit removal and a second process

line, which will be dedicated to industrial wastewater, for which there is provided a pre-
treatment of chemical-physical type.

After the pre-treatment steps, both sewage lines are equalized and subjected to
membrane biological remediation (MBR) with subsequent denitrification; traditional
sedimentation is replaced with a reverse osmosis (R.O.) treatment with final
evaporation-crystallization. The sludge line, finally, consists of a dehydration-type
centrifuge for both chemical and biological sludge, after stabilization with a dosage of
polyelectrolytes to improve the power of dehydration.
All plant sections are equipped with air intake systems in order to limit the emissions
of VOCs in the atmosphere, the air drawn in is treated through the passage within a
biomass filter biofilter, sized for a flow of about 3.000 Nm³/h.
