Ecodisk™ Filter

EcodiskTM Filter : what is it?

Ecodisk™ Filter

Ecodisk™ Filter is a unique technology developed by Veolia Water Technologies, thanks to the strong alliance between two subsidiaries; Hydrotech and PMT. That technology formed by a drum filter which is directly on the Ecodisk™ shaft. Pointedly designed for the needs of agressive discharge standards, Ecodisk™ Filter porposes a really low energy comsumption compared to similar technologies in the wastewater treatment market.


Its working principle is quite simple but also efficient. In additon to Ecodisk™ system, the main shaft contains a drum filter which is implemented in a seperated compartement.
The biological sludge conducting through the system by gravity is collected on the inner surface of the drum filter where the separation realises. Treated water at the downstream is also used for auto-cleaning of the drum system.

Just like all the produts in the Ecodisk family, the Ecodisk™ Filter has been designed with simplicity of operation in mind. The drumfillter is backwashed without any need for an industrial or drinking water connection.

Ecodisk™ Filter can also be fully integrated into a wastewater treatment system with a combination of pretreatment. A minimal screening is suggested to keep big particles. Pretreatment can always be enhanced by adding an anoxic chamber or a septic tank.

In operation, the EcodiskTM Filter is silent and odorless. The backwashing of the drum filter pannels is done through nozzles at a pressure of 6 - 8 bars. The nozzles are fed by a backwash pump integrated at the outlet of the drum. The sludge is extracted by gravity (no pump).

The avantages of the technology are :

  • Competitive investment cost
  • Automous treatment approach
  • Constant treated water quality, reliable process
  • Energy efficiency with the rotation of the drum filter by the same motor as the biodiscs
