1. Installation context
Icap-Sira is an Italian company specializing in the production and marketing of chemicals for the textile and nonwovens, coating and self-adhesive sectors. The company, founded in 1945, has its headquarters in the province of Milan and a production facility in Barberino di Mugello, in the province of Florence.
for this sector,The washing waters of pipes and transport vehicles, used for the production of these chemicals at the Barberino di Mugello site, are characterized by a high COD and surfactant content. For this reason, in 2018, Icap-Sira decided to renovate its treatment plant with The objective of ensuring a discharge to the sewage system that complies with the relevant Italian regulations.
The upstream supply chain of Icap-Sira’s wastewater treatment plant was already composed of a few processes: a storage tank for wash water, an initial chemical-physical treatment, and a sedimentation system to separate sludge flocs.
2. Proposed solution
MITA Water Technologies proposed the installation of two Biorulli®, one-piece series model M 240-50-1.
Biorulli® are a biological oxidation technology that is as simple as it is efficient. The bacterial flora that grows on the plastic discs,is alternately immersed in the slurry (where the microorganisms take up the orgnic substance needed for nourishment) and then brought into contact with the air where it becomes saturated with oxygen used to degrade the organic substance itself.
The two Biorulli® systems installed by MITA Water Technologies have an installed capacity of 1.50 kW each. The total active surface area of 3623 m2 for each bio-roller is achieved by installing a number of plastic discs.
3. The key to success
The installation of Biorulli® systems enabled Icap-Sira to achieve its goals. The key success factors of the intervention were as follows.
- Long successful partnership with the client: MITA Water Technologies supplied the first water treatment systems to the chemical company back in 2006.
- One-piece, compact equipment that is easy to install and maintain-all of which reduces plant operating costs.
- Low energy use solution: powering the system and operating it does not require high resource consumption.
