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.

Water is one of the most important raw materials for industrial production. For this reason, processes are now used in water treatment that not only produce the required water quality, but also allow for recycling. The treated water can either be fed back into the process, or reused for other purposes. Water recycling plants lead to a significant reduction in operational costs for production.

Waste water in this sector has a high concentration of heavy metals, oils and products in decomposition. The oils and emulgents lead to foam production at the water treatment plants. The treatment of these oils is very important.
