Key to Success
Speed of execution, quality and reliability of the proposed solution

1. Context of Installation

In 2022, the public body MM spa needs to improve the performance of the filtration section of the public sewage treatment plant in San Rocco (Monza province, Italy). It is decisive for the supplier to rely on an experienced supplier and quality made-in-Italy technology.

All this against a high volume of water flow: over 13,500 m³/h maximum flow rate, with an average flow rate of 7,500 m³/h and average peak flow rate of 10,500 m³/h. According to the studies conducted, the inlet water has an expected weighted average total suspended solids (SST) content of 10 mg/l and maximum SST of 35 mg/l.

2. Proposed solution

MITA Water Technologies offers the supply and installation of 12 free fiber cloth filters, model MSF 32/160 PPC HD: 32 filtering discs for 160 m2 total filtering surface area. These filters use gravity filtration technology: their configuration achieves high efficiency in the removal of suspended solids, ensuring an SST output of less than 5 mg/l. Due to their large filter surface area, the filters are also able to handle the required flow rate and maintain optimal performance even during peak loads.

Installation of the filters is followed directly at MITA Water Technologies, which also provides Brianza Acqueque with installation, transportation, installation assistance, start-up and testing services.

3. Results and key success factors

The proposed solution meets the customer’s needs in terms of improved performance, reliability and energy savings.

The key success factors: speed of project execution, confirmation of the quality of treated effluent, and reliability of the proposed solution.

Some MITA projects

Pile Cloth Filters for the Merone WWTP

The tertiary filtration of the Merone wastewater treatment plant bears the signature of MITA Water Technologies: six disc filters with fleece cloth were adopted for the final treatment of the water reaching the upper Lambro River. This is part of a larger project to rehabilitate the purification plant. The chosen solution is extremely flexible and also makes it easy to deal with sludge lifting phenomena, typically seasonal or resulting from periodic increases in effluent flow rates.
