Riso Scotti with Veolia Water Technologies for wastewater treatment
The rice farm will reuse the biogas produced during the process, within an integrated production cycle
Veolia Water Technologies Italia has been awarded a contract with Riso Scotti for the design and construction of a new waste water treatment plant (Wwtp) for its Pavia plant. The rice farm will reuse the biogas produced during the treatment process as clean energy within an integrated and circular production cycle. With a treatment capacity of 900 m3 / day, the purpose of this project purchased in the "Industry 4.0 Compliance Plan", includes the patented technologies Veolia Biothane Uasb and AnoxKaldnes Mbbr for the anaerobic and aerobic treatment of waste water, which will allow to achieve a efficiency up to 90% in the elimination of organic matter. The treatment line is completed by an Idraflot dissolved air flotation system for the final filtration phase of the effluents and an increase in the removal of solids.
In line with Riso Scotti's environmental sustainability program, inspired by a circularity model, the biogas produced during the anaerobic phase will be valorised as energy to be reused as part of a perfectly integrated production cycle. This contract is the result of a thorough audit of the water cycle carried out at the plant, which ended with a pilot project that demonstrated the efficiency of the treatment line proposed by Veolia Water Technologies. In fact, the return on investment, which will allow the company to have its own Wwtp, is estimated at around 400,000 euros per year.
"Riso Scotti's story is a story of continuity linked to tradition and innovation", says the energy, safety & environment manager Lorenzo Cerri. "Ours is no longer a rice mill, but a real food industry, which uses natural resources and by-products of rice processing to produce those energy carriers, primarily steam, necessary for the processing of rice. The excellence of a company lies in the ability to innovate products but also to innovate processes, so that they are performing, efficient and less impactful". Olivier Jenoc, CEO of Veolia Water Technologies for Southern Europe and Germany, said: “We are very proud to have been able, in a short period of time, to put together a customized technology solution based on our standard products. This project perfectly exemplifies how Veolia can help companies achieve their production goals in a sustainable way”.
