Compact waste water treatment Cella™

biologicalactivated sludge

Turning wastewater treatment into a renewable resource supply and creating value through responsible and sustainable solutions is now possible. Cella™ is a biofilm technology utilizing the power of nature to provide flexible, compact and robust wastewater treatment while minimizing the use of fossil resources and maximizing energy efficiency and recovery without compromising treatment performance. Cella is a new biofilm technology developed with a strong emphasis on sustainability, reuse and ensuring clean water for future generations. Designed to maximize energy efficiency and recovery in the form of biogas from excess biomass, Cella promotes a positive energy balance in treatment plants. Furthermore, this technology facilitates the integration of biological phosphorus removal into the treatment process, reducing reliance on chemicals for phosphate precipitation. How does Cella™ work? Cella features the Moving Bed Biofilm Reactor (MBBR) technology while incorporating additional benefits, including a new biobased support material for biofilm growth, no limitation in biofilm surface with high treatment rates, and an all-in-one solution for the treatment of carbon, nitrogen and phosphorus. The exposed surface facilitates efficient mass transfer into and out of the biofilm, resulting in a highly effective process that can handle high loading rates within a small footprint. Cella combines the flexibility of the activated sludge process with the compactness and stability of biofilm processes – in one and the same tank.
