DRAFTING OF TECHNICAL VARIANT EXPERTISE FOR THE ADJUSTMENT OF THE PURIFICATION PLANT IN MONTECCHIO

BRIEF DESCRIPTION OF THE INTERVENTION:

The variant appraisal involved the expansion of the purification plant located in loc. Montecchio, so as to serve a future population of 30,000 AE unlike the 10,000 previously treated.

The priority was to create a complete wastewater treatment chain, which was then discharged onto the surface water body.

The appraisal involved the lifting and initial treatment sections, a new configuration of the biological tanks, designed with alternating cycle technology, so as to avoid hydraulic short circuits, as well as the creation of new disinfection compartments with consequent review of the entire piping.

Furthermore, the layout has been enriched with a new mechanical pre-thickening section on the sludge line.

Finally, the booties treatment section was completely revised with the implementation of a sub-vertical grid.
