Acque Novara, a public utility in the Province of Verbano-Cusio-Ossola, needed to improve the performance of Gravellona Toce’s municipal water treatment system. MITA Water Technologies responded to the needs by supplying three free-fiber cloth filters, each with 12 discs and a filtering surface area of 60m². The made-in-Italy technology and speed of execution were successful.
Acque Novara, a public agency operator in the Province of Verbano-Cusio-Ossola (Italy), needed to replace the existing filters of the public sewage treatment plant in order to achieve better performance in treating municipal water in Gravellona Toce.
Acque Novara turned to MITA Water Technologies. MITA proposed the use of three pile (or “free-fiber”) cloth filters, model MSF 12/60 PEC, each equipped with 12 discs and a filtering surface area of 60m² per device. This advanced filtration technology was integrated into the downstream supply chain of the secondary sedimentation process. Some of the services provided to the partner, in addition to the supply of the machinery: on-site transportation, assembly assistance, machine start-up and testing.
The cloth filters supplied by MITA Water Technologies exceeded expectations. They successfully handled a maximum flow rate of 1,125 cu m/h and an average flow rate of 325 cu m/h, ensuring optimal operating efficiency. In addition, the concentration of total suspended solids (TSS) at the inlet, which was 35 mg/l, was reduced to only 10 mg/l at the outlet, significantly improving the quality of treated water.

With these free-fiber filtration systems, we get to serve medium to large sewage treatment plants with minimal floor space requirements. Not only that. In the PEC and PEC VM disc filters, backwashing with sequentially driven pumps provides the machine with operational continuity in water treatment, consequently avoiding the need to provide a back-up unit.
In this area, contractors and engineering firms contacted by municipalities face a number of challenges: knowledge of regulations, managing costs, and selecting cost-effective solutions. MITA Water Technologies can support them with its efficient and easy-to-manage solutions.
MITA Water Technologies has supplied Acquedotto Pugliese with 6 MSF 12/60 PEC pile cloth media filters for the Barletta sewage treatment plant. The filters, housed in concrete tanks, ensured a SST concentration of less than 10 mg/l. The solution met the customer's needs, supported by an expected power consumption of about 11 kWhour/d. MITA Water Technologies provided comprehensive support, ensuring the success of the project.
