Ozone treatment removes problem with filamentous sludge at activated sludge process plants

Ozone breaks up filaments and improves settling characteristics of the sludge…

Filamentous sludge is a common problem at activated sludge plants. With ozonation of the return sludge flow it is possible to reduced the amount of filamentous bacteria in the sludge and significantly increased the settling properties of the sludge.This in turn means better performance of the activated sludge process
When a bioreactor is connected to the sludge line the removal of the damaging filamentous bacteria means higher quality sludge in the bioreactor, which leads to higher biogas production.

…without any negative effect on the nitrification or the biological phosphorus separation

In the treatment of filamentous sludge ozone breaks up the filaments and improves the settling characteristics of the sludge, without any negative effect on the important nitrification process or the biological phosphorus separation.
