Cella™ is a new biofilm technology for efficient and sustainable wastewater treatment.
Overview
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.

FAQ about Cella
What are the benefits of biological treatment?
Wastewater biological treatment offers various benefits, including the efficient elimination of contaminants that has a favorable impact on the environment. The financial impact of the process is also reduced, as biological treatment is cheaper than physical chemical treatments.
AnoxKaldnes' Cella™ technology utilizes nature's power to improve sustainable wastewater treatment at a low cost, with a high quality result, and with a minimal footprint.
How is the biofilm in CellaTM used for wastewater treatment?
Cella is a technology in which microorganisms grow on the external surface of a support material , resulting in the creation of a biofilm. These microorganisms thrive from removing contaminants from wastewater which they use as a food source. By removing these contaminants, microorganisms clean the wastewater to the required treatment parameters. Some of these organisms require very specific conditions which are ensured in a biofilm and the biofilm protects them from external inhibitory conditions.
In the biofilm, microorganisms can grow in layers or zones under different conditions depending on the biofilm thickness (aerobic, anoxic, anaerobic), which allows for an efficient all-in-one treatment of carbon, nitrogen and phosphorus.
Cella™ is a new biofilm technology for efficient and sustainable wastewater treatment.
How does biological phosphorus removal work?
Biological phosphorus removal takes place in the biofilm by promoting the growth of phosphorus-accumulating bacteria under anaerobic and aerobic conditions with the availability of easily degradable carbon.
In CellaTM, phosphorus accumulates inside the microorganisms in the biofilm, and due to natural biofilm sloughing, excess biomass containing phosphorus exits the process in the form of suspended solids. After downstream effluent suspended solids separation, the wastewater leaving the treatment process contains the desired low phosphorus levels.
Case Studies
The municipal wastewater treatment plant, Svinninge, located in Holbᴂk is an activated sludge plant mainly receiving wastewater from households and a few industries. Working beyond its permissible capacity, the client needed to increase the existing plant’s capacity to ensure effective treatment. In order to meet our client’s needs, Cella was chosen, this decision having been driven by the technology’s sustainability and small ecological footprint as well as the compactness and efficiency of its process.
