Disk Filter
Mecana Disk Filter
The Mecana Disk Filter (MSF) was developed for high hydraulic capacity. Mecana's outstanding operational experience in a wide range of municipal and industrial applications is a unique selling point.
The MSF consists of six segments per disk (5 m² filter surface per disk), which are mounted onto the central tube. According to the application, the distance between the disks is either 180, 240 or 300 mm. Every two/three disks have their own independent cleaning system, consisting of pivoting suction beams with (profiled) suction lip and a filter cleaning pump. The filter cleaning can also be performed with one central pump and one valve per cleaning system. However, filter systems with one filter cleaning pump per two/three filter disks offer advantages in terms of operational reliability.
How Disk Filter works
The Mecana Disk Filter is mounted in a filter tank equipped with an inlet and outlet weir for hydraulic decoupling as well as an emergency overflow and level measurement. The water flows through the fully submerged filter structure from the outside to the inside passing the pile layer and retaining the solids. Filtrate flows over the rising chamber and through the outlet weir. The outlet weir defines the zero-water level, which serves as a reference for system control. The filter media is cleaned by rotating the disc without interrupting the filtration process. Within one cleaning cycle, the entire filter surface is cleaned. In automatic mode, cleaning is either level-controlled or time-controlled. Within one cleaning cycle, the entire filter surface is cleaned. Suspended solids are intermittently removed from the bottom of the filter.

Mecana Aqua MegaDisk®
Mecana Aqua MegaDisk is the big brother of the MSF and offers the same advantages but extends the exceptional performance by increasing the disk diameter. The MegaDisk consists of eight interchangeable segments per disk (10 m² filter surface per disk), which are mounted on the central tube. The distance between the disks is 230 mm. Filter cleaning is performed using a central pump and a valve for each cleaning system.
Key Information
- 8 segments per disk (10 m²/disk)
- Up to 24 disks per filter
- Lightweight segments, removable without crane
- Easy replacement of the filter media (filter cloth)
- Disk diameter: 2,900 mm
- Distance between the disks: 230 mm
- Hydraulic capacity per unit up to over 3,800 m³/h
- MegaDisk available in different steel qualities (1.4301, 1.4404, Duplex or Super Duplex)
- Installation in concrete or steel tanks
- Low-maintenance and powerful peripherals
- MegaDisk with dry-mounted pump
- Modular system ideal for every customer requirement
