Enhancement of the water treatment plant and related collectors and distribution conduits in Priolo (Italy)

The project includes the development of waste water collectors, upgrading and enhancement of the existing treatment plant and the distribution conduits of treated waste water for industrial use. The following works were carried out:

• renovation of 3 lines out of 4 of the existing refining section (tertiary treatment) with focus on the flocculation and lamellar clarification steps for a total potential capacity of 1,200m3h-1;
• the new accumulation (500m) and release (1,200m3h-1) tank for clarified waters;
• the new desalination section on 4 lines, each of 300m3h-1 capacity, based on the following steps: multilayer filtration (sand and anthracite) under pressure with in-line flocculation, dosing of bactericidal solution, cartridge microfiltration, dosing of anti-precipitant solution, two-stage osmosis process, accumulation, pH adjustment and release of desalted water, concentrated accumulation and release.
