In 2023, MITA Water Technologies improved the wastewater treatment system i Trenitalia in Sassari. How? With a new simple and efficient lamella-pack oil separator, which replaced an outdated system.
In 2023, MITA Water Technologies collaborated with Trenitalia S.p.A., Italy’s leading passenger rail transport company, to improve the efficiency of civil wastewater treatment at the current maintenance plant in Sassari, Sardinia. This plant was equipped with an obsolete lamella-pack oil separator that was no longer adequate for current water management needs. The primary need was the removal of oils in the wastewater, with a maximum inlet concentration of 1 mg/l, to ensure compliance with current environmental regulations. The maximum flow rate of the pre-treatment plant: 30 m³/h.
MITA Water Technologies proposed the installation of a new lamella-pack oil separator (settler), model OM 85-2-110: a one-piece solution, with a projected surface area of 34 m², chosen for its reliability and ability to remove oils efficiently even under heavy use.
In addition to the supply of the oil remover, MITA offered a comprehensive service that included:
The implementation of the new system has enabled Trenitalia to optimize the wastewater pre-treatment process, significantly reducing maintenance costs and improving oil removal efficiency. The installed oil separator fully met the required technical requirements, keeping oil levels below the maximum threshold of 1 mg/l. In addition, MITA’s intervention made it possible to comply with local environmental regulations, ensuring continuous and reliable operation of the plant.
The critical success factor was the advantageous economic offer combined with the comprehensive services provided by MITA Water Technologies, which followed all phases of the project, from design to installation and commissioning, thus providing constant technical support.
