Upgrading of the Bergamo purification plant - Lot 1

Uniacque S.p.A. of Bergamo

Coarse and fine screening, mechanical primary sedimentation, optimisation of the denitrification section

Purpose of the project

The intervention concerns the realisation of Lot I of the upgrading works of the Bergamo purification plant, divided, for financial coverage reasons, into several functional lots. The purpose of Lot I is to allow the pre-treatment of the maximum rainfall flow rate, equal to about 7,000 m3/h and the second stage treatments for a flow rate of 3,000 m3/h. Subsequent functional lots will involve the further adaptation of the second stage treatments and the sludge line.

Project Plus

Coarse and fine screening installation without modification of the hydraulic system profile.
Introduction of primary mechanical sedimentation to reduce the organic load entering the biological compartment and recover organic matter to be sent to anaerobic digestion.
Optimisation of the pre-denitrification section to reduce the concentration of the nitrate parameter at the discharge, with alleviation of the existing post-denitrification phase.
