Pilot study at Oresundsverken, NSVA, WWTP

A pilot study at the Swedish WWTP Oresundsverket showed that at lines treated with ozone the Sludge Volume Index was reduced dramatically while the nitrification process was not affected.

Improved sludge - higher biogas production

When a bioreactor is connected to the sludge line the removal of the damaging filamentous bacteria means higher quality sludge in the bioreactor, which means higher biogas production.

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.

With the Primozone SM900 you have a complete and containerized ozone system for treating filamentous sludge

The Primozone SM900 is a complete ozone system housed in a small container. Convenient and with a short installation time. It is a perfect solution for treating filamentous sludge as it can easily be placed close to the activated sludge process.
