K5 media is used to collect biofilm, reducing required footprint and allowing for future facility expansion without additional construction. **BIOMASS BIOFILM TECHNOLOGY** [**Cella™**](https://www.anoxkaldnes.com/en/discover-cella "AnoxKaldnes Cella Biofilm Technology") is at the forefront of biofilm technology, offering an innovative approach to wastewater treatment that's both efficient and sustainable. By integrating the strengths of Moving-Bed Biofilm Reactor (MBBR) technology with a new biofilm support material made of renewable biomass by-products, Cella represents a significant leap forward in ecological transformation. **DEAMMONIFICATION MBBR AND IFAS PROCESS** [**ANITA™ Mox**](/en/solutions/technologies/anita-mox "ANITA™ Mox") is a robust, single-stage nitrogen and ammonia removal process with low carbon footprint. This activated sludge process is based on the MBBR or IFAS platform utilizing K5 media to cultivate anammox enriched biomass for mainstream and sidestream deammonification applications. The ANITA™ Mox process is specially developed for treatment of streams highly loaded in ammonia, such as effluents from anaerobic treatment, drying condensates, centrates, industrial wastewaters, and landfill leachates. **Lagoon Treatment** [**LagoonGuard**™](https://www.veoliawatertech.com/en/solutions/technologies/anoxkaldnes-lagoonguard "AnoxKaldnes™ LagoonGuard™") has long been known for its consistent ammonia removal. Built upon the MBBR moving bed biofilm reactor platform, LagoonGuard provides robust nitrification in concert with the site’s existing lagoons. Now, LagoonGuard has just become simpler for small and medium-sized lagoon systems required to meet ammonia limits. **BIOLOGICALLY ACTIVE FILTER ( BAF ) TECHNOLOGIES** [**BIOSTYR®**](/en/solutions/technologies/biostyr "Biostyr™") is a biological aerated filter ( BAF ) that combines biological treatment and tertiary filtration into one compact biological filter system. BIOSTYR DUO adds a second media layer for increased carbon, solids and nitrogen loading capabilities. With over 160 installations throughout the world, BIOSTYR is proven to be an exceptional technology for BOD removal, nitrification, denitrification and solids removal, with improved energy efficiency and 20% of the footprint of conventional activated sludge technologies. **ACTIVATED SLUDGE TECHNOLOGIES** We offer a wide range of solutions for activated sludge treatment providing our clients guaranteed total process performance with a single point of responsibility. The core offerings in our Activated Sludge Systems are based on [**Phased Isolation Ditch**](/en/solutions/technologies/oxydation-ditch-technologies-double-ditch-triple-ditch "Oxydation Ditch Technologies Double Ditch / Triple Ditch ") technology, or Phased Isolation Technology. Phased Isolation Technology is a type of continuous flow activated sludge process, used in our [**Bio-Denitro Oxidation Ditch**](/en/solutions/technologies/biodenipho-biodenitro "Biodenipho™ / Biodenitro™") system, wherein one or more reactors alternate between oxic and anoxic phases. Alternating phases are controlled by a timed sequence or online nutrient monitoring. These systems offer very efficient enhanced nutrient removal without multiple reactor zones or MLSS recycle loops. **ONSITE BIOLOGICAL SOLUTIONS** Veolia is an expert and a leading producer of packaged biological treatment solutions, including [**Ecosim**](/en/ecosim-rotating-mbbr "Ecosim Rotating MBBR") rotating MBBR and [**Ecodisk**](/en/ecodisk "Ecodisk") (Filter, M & DL).. These compact biological wastewater treatment plants have been utilized worldwide for over 20 years; providing small and medium sized solutions that integrate easily into the existing landscape with minimal odor.
