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.

Multiple treatment reactions and benefits are obtained at ozonation, all at the same time. Ozone based advanced oxidation processes are important because of reactions with organic molecules that are not readily oxidized by ozone. One challenge beverage suppliers face is the need to deliver a product free of bacteria and with extended shelf life. Because of its powerful disinfectant properties, environmentally clean treatment process and its oxidative ability, ozone has become the technology of choice among water bottlers worldwide.
