Ozone treatment removes filamentous sludge problem at activatedsludge processing plants

Ozone breaks up filaments and improves settling characteristics of sludge…

Filamentous sludge is a common problem at activatedsludge plants. Ozonation of the return sludge flow makes it possible to reduce filamentous bacteria levels in the sludge while significantly increasing sludge settling properties. This in turn improves the performance of activatedsludge processes.
When a bioreactor is connected to the sludge line, the removal of damaging filamentous bacteria results in higher quality sludge in the bioreactor, which leads to increased biogas production.

…without any negative effect on nitrification or biological phosphorus separation

In 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 biological phosphorus separation.
The Primozone SM900: a complete, containerized ozone system for treating filamentous sludge

The Primozone SM900 is a complete ozone system housed in a small, cargo container-style unitthat’s convenient and quick to install. It a perfect solution for treating filamentous sludge because it’s easy to place the SM900 close to the activatedsludge process.
