Ecodisk™ Denit: what is it?

Ecodisk™ Denit

Ecodisk™ Denit is a wastewater treatment system developed by PMT and Veolia Water Technologies for the treatment of total nitrogen via denitrification. Specifically designed for the needs of TN regulations, Ecodisk™ Denit modules can be porposed in upstream and/or downstream of Ecodisk™ modules to reach a complete treatment of nitrogen from the influent wastewater.


Ecodisk™ Denit can also be fully integrated into a wastewater treatment system by a combination of pretreatment. A minimal screening is suggested to keep big particles. Pretreatment can always be enhanced like anoxic chamber or digester-settler structure.

Its working principle is quite simple but also efficient. In additon to Ecodisk™ system, the denitrification units are sealed and well isolated to create an anaerobic environment for the denitrifiers. Denitrification units are tested with pressure gauges in PMT workshop before the delivery and commissioning.
