The civil sewage treatment plant in San Martino di Castrozza, Trentino, has also been expanded with a pile cloth filtration section.
The resort of San Martino di Castrozza, in the province of Trento, is a well-known tourist destination. The resort’s civil sewage treatment plant serves a population of about 7,000, in addition to the seasonal tourist flow.
In 2012, the San Martino di Castrozza sewage treatment plant underwent tertiary finishing treatment upgrades.
MITA Water Technologies S.r.l. contributed to the implementation of this intervention by supplying three disc filters mod. MSF 8/40.
The tertiary finishing treatment, needed at the San Martino di Castrozza plant, was aimed at removing suspended solids that may leak from the secondary settling and those formed in the phosphorus post-precipitation section. Inlet total suspended solids values: less than 40 mg/l.
MITA Water Technologies proposed the installation of three disc filters mod. MSF 8/40. MITA’s free-fiber ply filters allow depth filtration in strong analogy with sand filters, for very high efficiency of suspended particle removal.
The total filtering surface area is 120 m2, allowing the expected value for the TSS parameter to be achieved.
The upgrading of tertiary finishing treatment at the San Martino di Castrozza plant achieved the following objectives.
A solution for high filtration yields and efficient handling and backwashing, with only two pumps for the whole system: the PPC and PPC VM disc filters are for concrete or metal tank, respectively. Versatility and little ancillary work required for operation.
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.
It is one of the largest tertiary filtration systems in Europe: the MITA supply for the vast Cuma water treatment plant near Naples, having a treatment capacity of 1,200,000 population equivalents. The goal of the project was to improve the plant's purification performance.
