Ozone treatment removes filamentous sludge problem at activated–sludge processing plants
Ozone breaks up filaments and improves settling characteristics of sludge…
Filamentous sludge is a common problem at activated–sludge 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 activated–sludge 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 activated–sludge process.
Main benefits
Improves the activated sludge process
Increases throughput of your plant
Short installation time
Improved sludge – higher biogas production
The distinctive smell of hydrogen sulfide (H2S) was a nuisance to the neighborhood close to the Mestilla bio-disel plant. With the Primozone ozone odor control solution the odor was efficiently eliminated.
