Polcevera Valley Wastewater Treatment Plant in Genoa (Italy)

Construction:

• Technology and design: Italimpianti (now Fisia Italimpianti), with proprietary expertise.
• Construction and plant integration: local civil and industrial infrastructure

Production capacity:

• Flow rate: 1,300 m³/hour.
• Production of purified water for industrial use.

Technology used – Pure oxygen biological treatment:
The treatment cycle involves a biological process using activated sludge with pure oxygen, completed by tertiary treatment of the purified water through sand filtration and chlorination. This produces water of a quality reusable for industrial purposes, reducing waste and increasing overall efficiency.

Sludge treatment:
The resulting sludge is thickened, dewatered using centrifuges, and then dried, ready for disposal.

Technological advantages:
The pure oxygen system allows for significant space and energy savings compared to traditional air processes and guarantees higher overall purification efficiency, anticipating the sustainability and water reuse requirements that are now benchmarks.
The Val Polcevera plant represents a pioneering example of integrating advanced biological treatment and water reuse, paving the way for more efficient and sustainable industrial solutions nationwide.
