Centrale del latte di Brescia clears odor problems and upgrades CIP process with Mellifiq advanced treatment solutions
Centrale del Latte di Brescia is a dairy factory founded in 1931 in the town of Brescia, in the northern Italian region of Lombardy. It has been producing continuously during the past 90 years, even during the Second World War. Continuous improvement is one of the core values of the Centrale – it was the first dairy factory in Italy to incorporate UHT pasteurization into their production process.

As the factory was built not far from the current city center, it is surrounded by a relatively dense residential area. Dairy products may involve lactic fermentation among other processes that result in residues emitting odorous compounds. These residues are discharged in the factory’s process water and the odorous compounds enter the ventilation system, being subsequently released into the surrounding environment.
In this case, the odor problem resulted in both the neighbors and the municipality to file complaints against Centrale del Latte di Brescia.
The complaints have determined the company management to start looking for an efficient odor control solution. As a company with a vision for sustainability, they looked for a solution that can solve the odor problem and at the same time lower the environmental impact of the production.
Besides solving the environmental issue caused by odors, Centrale del Latte di Brescia decided to reduce the use of fresh water by treating and reusing it in their equipment clean-in-place (CIP) process.
Since the Centrale required a sustainable, effective and innovative solution, they chose Mellifiq for this project. In our turn, we delivered a system consisting of an Ozonetech RENA Pro B4 turn-key ozone system and two Nodora ADS A-series.
The system is connected to the factory’s ventilation system, where it treats the air in two stages, before releasing it into the environment. In the first step, ozone is injected into the ventilation duct, breaking down most of the odorous compounds. Afterwards, the remaining air passes through the Nodora adsorption modules, where remaining odorous compounds are adsorbed by the activated carbon.
The Italian dairy factory was also looking to improve their clean-in-place process. Ozone treatment can decontaminate wastewater from the dairy production to the point that it can be reused to clean the production equipment.
Hence, Centrale del Latte di Brescia has placed a second order from Mellifiq, for an Ozonetech RENA Vivo B4 ozone system, along with automation (Ph sensor, ORP sensor). Our solution is fully compatible with the EU initiative Industry 4.0, with its high level of automation and remote monitoring.
The odor control solution achieved 90% removal of odorous compounds in the preliminary evaluations after the installation, along with over 90% lower organic contamination levels and disinfection in the water reuse system.
