Castiglione, Italy
By working in partnership with their water treatment supplier, the site have been able to reduce the cooling towers blowdown frequency through the use of different treatment chemicals. This will save 22,585 m3 of water per year.
Improvements were made to improve the efficiency of the onsite bio-treatment plant. The build-up of foam in the lagoons reduced the breakdown of CO2. A series of water jets were installed to spray over lagoon to reduce the foam. Initially fed with fresh well water the site were able instead to recover clean water flowing from the bio station itself and use it to feed the spray system. In total this will save 18,000 m3 of water per year.
