Carra Purifications

CARRA Depurazioni has been present on the national and international markets since the early 1970s, designing, building, and maintaining purification plants for domestic, industrial, rainwater, and primary wastewater.
In the field of municipal wastewater treatment (domestic wastewater), our experience ranges from the construction of small purification plants serving a single household to the construction of plants serving agglomerations with several thousand equivalent inhabitants (municipalities, hospitals, nursing homes, tourist hotels, campsites, shopping centers, etc.). The techniques used meet the designer’s needs and range from the most advanced (e.g., MBR) to those—equally advanced from a design perspective—that prioritize lower environmental impact and energy consumption (vertical flow constructed wetlands).
The industrial wastewater treatment systems we work with serve wineries, agri-food companies, milking parlors, ferrous metal collection centers, car washes, industrial dry cleaners, pharmaceutical companies, landfill leachate, digestate, and process water in general. We utilize biological, chemical-physical, MBR, filtration, reverse osmosis, and other treatment techniques.
Carra Depurazioni is also very active in the treatment of rainwater for paved surfaces, such as roads and highways, intermodal areas, and transit and parking areas. In this sector, we have been and continue to be a key partner in the construction of major road infrastructure projects, such as the expansion of the A1, A4, A7, and A14 motorways, the Pedemontana Lombarda and Veneta highways, the Palermo, Treviso, and Orio al Serio airports, as well as new integrated logistics and large-scale retail outlets, Terna stations, and more.
Our rainwater treatment systems are constructed with prefabricated vibrated reinforced concrete tanks, monolithic, parallelepiped, or cylindrical, with a potential internal volume of up to 62 cubic meters in a single unit. The tanks can be connected together to create storage basins with a total capacity of hundreds of cubic meters. Our products are certified by a third-party body.
In the primary water sector, our systems include filtration, ultrafiltration, and nanofiltration treatment, as well as resins and reverse osmosis. We specialize in potable water and PFAS abatement.
Each of our systems is designed to meet the client’s specific needs and is developed specifically for the specific characteristics of the wastewater to be treated, the installation site, and the project’s context. This allows us to best manage the entire life cycle of a project, from initial site inspections to delivery and system start-up.
